This supports the -spice argument posted for review against
the latest upstream QEMU/KVM. This supports the bare minimum
config with port, TLS port & listen address. The x509 bits are
added in a later patch.

This supports the '-vga qxl' parameter in upstream QEMU/KVM
which has SPICE support added. This isn't particularly useful
until you get the next patch for -spice support. Also note that
while the libvirt XML supports multiple video devices, this
patch only supports a single one. A later patch can add support

The patch is based on the possiblity in the QEmu command line to
add -smbios options allowing to override the default values picked
by QEmu. We need to detect this first from QEmu help output.
If the domain is defined with smbios to be inherited from host
then we pass the values coming from the Host own SMBIOS, but
if the domain is defined with smbios to come from sysinfo, we
use the ones coming from the domain definition.
* src/qemu/qemu_conf.h: add the QEMUD_CMD_FLAG_SMBIOS_TYPE enum
value
* src/qemu/qemu_conf.c: scan the help output for the smbios support,
and if available add support based on the domain definitions,
and host data
* tests/qemuhelptest.c: add the new enum in the outputs
libvirtd.conf uses "libvirt" as the value of "unix_sock_group",
however, group "libvirt" may not exist on the system, in this case
the case will always fail.
As a solution, replace "libvirt" with "$USER" in "tmp.conf".
When using 0-prefixed numbers, QEmu will interpret them as octal numbers
(as C convention says); this means that if you attach a device that has
addr > 10 (decimal) you're going to attach a different device.
So far, readonly=on option is used when qemu supports -device. However,
there are qemu versions which support readonly option with -drive
although they don't have support for -device.
Add a test suite for check parsing, formatting, range calculation
and netmask checking APIs in virSocketAddr.
* tests/sockettest.c, tests/Makefile.am: Add new test case

* tests/qemuhelptest.c: cope with the extra flag being detected now
The statstest is xen specific. Instead of filling the code with
a huge number of #ifdef WITH_XEN, just make its entire compilation
conditional in the Makefile.am. Also ensure it links to the Xen

This enables support for nested SVM using the regular CPU
model/features block. If the CPU model or features include
'svm', then the '-enable-nesting' flag will be added to the
QEMU command line. Latest out of tree patches for nested
'vmx', no longer require the '-enable-nesting' flag. They
instead just look at the cpu features. Several of the models
already include svm support, but QEMU was just masking out
the svm bit silently. So this will enable SVM on such
models

Adds a new specific test
This patch adds a test case for testing the XML parser's and instantiator's

capabilities. Both test cases will be used in TCK again.
Since version 4.1 ESX(i) can expose virtual serial devices over TCP.
Add support in the VMX handling code for this, add test cases to cover
it and add links to some documentation.
ESX supports two additional protocols: TELNETS and TLS. Add them to
the list of serial-over-TCP protocols.
Description: Implement AppArmorSetSecurityHostdevLabel() and
AppArmorRestoreSecurityHostdevLabel() for hostdev and pcidev attach.
virt-aa-helper also has to be adjusted because *FileIterate() is used for pci
and usb devices and the corresponding XML for hot attached hostdev and pcidev
is not in the XML passed to virt-aa-helper. The new '-F filename' option is
added to append a rule to the profile as opposed to the existing '-f
filename', which rewrites the libvirt-<uuid>.files file anew. This new '-F'
option will append a rule to an existing libvirt-<uuid>.files if it exists,
otherwise it acts the same as '-f'.
load_profile() and reload_profile() have been adjusted to add an 'append'
argument, which when true will use '-F' instead of '-f' when executing
virt-aa-helper.
All existing calls to load_profile() and reload_profile() have been adjusted
to use the old behavior (ie append==false) except AppArmorSetSavedStateLabel()
where it made sense to use the new behavior.
This patch also adds tests for '-F'.

It's not a real failure (which is why the test was completing
successfully), so much as an intentional warning to the user that use
of the qemu namespace has the potential for undefined effects that
leaked through the default logging behavior. After this patch series,
all tests can access any logged data, and this particular test can
explicitly check for the presence or absence of the warning, such that

Reported by Mitchell Hashimoto.
The current code will go into an infinite loop if the printf generated
string is >= 1000, AND exactly 1 character smaller than the amount of free
space in the buffer. When this happens, we are dropped into the loop body,
but nothing will actually change, because count == (buf->size - buf->use - 1),
and virBufferGrow returns unchanged if count < (buf->size - buf->use)
Fix this by removing the '- 1' bit from 'size'. The *nprintf functions handle
the NULL byte for us anyways, so we shouldn't need to manually accommodate
for it.
Here's a bug where we are actually hitting this issue:
https://bugzilla.redhat.com/show_bug.cgi?id=602772

make sure we report buffer error if snprintf fails
v3: Add tests/virbuftest which reproduces the infinite loop before this

Instead of splitting the path part of a datastore path into
directory and file name, keep this in one piece. An example:
"[datastore] directory/file"
was split into this before:
datastoreName = "datastore"
directoryName = "directory"
fileName = "file"
Now it's split into this:
datastoreName = "datastore"
directoryName = "directory"
directoryAndFileName = "directory/file"
This simplifies code using esxUtil_ParseDatastorePath, because
directoryAndFileName is used more often than fileName. Also the
old approach expected the datastore path to reference an actual
file, but this isn't always correct, especially when listing
volumes. In that case esxUtil_ParseDatastorePath is used to parse
a path that references a directory. This fails for a vpx://
connection because the vCenter returns directory paths with a
trailing '/'. The new approach is robust against this and the
actual decision if the datastore path should reference a file or
a directory is up to the caller of esxUtil_ParseDatastorePath.
Update the tests accordingly.
RHEL-5 Xen doesn't support the old style vnc configuration. In sexpr, we
can't really check it with rhel5-api turned on. However, for XM
configuration files it's sufficient to use cfg version 1 instead of 2.
The most common cause of errors with rhel5-api turn on was missing
"(type ioemu)" in sexpr or its equivalent in XM configuration file. This
happens because the presence of that part in sexpr (or cfg) depends on
xen version the host is running. Let's avoid it by explicitly specifying
interface model which ensures "type ioemu" will always be emitted.
This patch adds
<model type='e1000'/>
withing the interface element in all affected xml files. And
(model 'e1000')
to all corresponding sexpr files with similar fix to cfg files. Such
configuration works regardless on Xen version.
I wrote a patch to add support for listing the Vendor and Model of a
storage pool in the storage pool XML. This would allow vendor
extensions of specific devices. The patch includes a test for the new
attributes as well.

floppy0.present defaults to true. Therefore, it needs to be
explicitly set to false when the XML config doesn't specify the
corresponding floppy device.
Also update tests accordingly.
Introduce esxVMX_Context containing functions pointers to
glue both parts together in a generic way.
Move the ESX specific part to esx_driver.c.
This is a step towards making the VMX code reusable in a
potential VMware Workstation and VMware Player driver.
According to <xen-3.4.3/tools/python/xen/xm/create.py:158>
gopts.var('bootargs', val='NAME',
fn=set_value, default=None,
use="Arguments to pass to boot loader")
the "bootloader_args" parameter needs to be translated into "bootargs"
when using "virsh domxml-to-native xen-xm".
The reverse direction (domxml-from-native) is already okay.
This patch fixes domxml-to-native and adds two test files to catch this
problem.

All <console> devices now export a <target> type attribute. QEMU defaults

Add a new element to the <os> block:
<bootmenu enable="yes|no"/>
Which maps to -boot,menu=on|off on the QEMU command line.
I decided to use an explicit 'enable' attribute rather than just make the
bootmenu element boolean. This allows us to treat lack of a bootmenu element
as 'use hypervisor default'.
Commit 68719c4bdd added the disk format
probing option. This makes virt-aa-helper-test fail because the domain
config didn't specifiy the disk format and it didn't pass '-p 1' to
virt-aa-helper to allow disk format probing.
Specify the disk format in the domain config. Pass the '-p 1' option
to virt-aa-helper for the test case with two disks. This way this test
also covers this new option.
Thanks to DV for knocking together the Relax-NG changes

To try and ensure that people upgrading from old QEMU get guests
with the same PCI device ordering, change the way we assign addrs
to match QEMU's default order. This should make Windows less
annoyed.
* src/qemu/qemu_conf.c: Follow QEMU's default PCI ordering
logic when assigning addresses
* tests/*.args: Update for changed PCI addresses
To allow compatibility with older QEMU PCI device slot assignment
it is necessary to explicitly track the balloon device in the
XML. This introduces a new device
<memballoon model='virtio|xen'/>
It can also have a PCI address, auto-assigned if necessary.
The memballoon will be automatically added to all Xen and QEMU
guests by default.
* docs/schemas/domain.rng: Add <memballoon> element
* src/conf/domain_conf.c, src/conf/domain_conf.h: parsing
and formatting for memballoon device. Always add a memory
balloon device to Xen/QEMU if none exists in XML
* src/libvirt_private.syms: Export memballoon model APIs
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Honour the
PCI device address in memory balloon device
* tests/*: Update to test new functionality
Disk format probing is now disabled by default. A new config
option in /etc/qemu/qemu.conf will re-enable it for existing
deployments where this causes trouble
By specifying <vendor> element in CPU requirements a guest can be
restricted to run only on CPUs by a given vendor. Host CPU vendor is
also specified in capabilities XML.
The vendor is checked when migrating a guest but it's not forced, i.e.,
guests configured without <vendor> element can be freely migrated.
The previous change which split -nodefconfig probing off
from -device broke the test case because it missed adding
the QEMUD_CMD_FLAG_NODEFCONFIG to the test
* src/util/bridge.c: Set QEMUD_CMD_FLAG_NODEFCONFIG for all
configs with QEMUD_CMD_FLAG_DEVICE set
Also don't abuse the disk driver name to specify the SCSI controller
model anymore:
<driver name='buslogic'/>
Use the newly added model attribute of the controller element for this:
<controller type='scsi' index='0' model='buslogic'/>
The disk driver name approach is deprecated now, but still works for
backward compatibility reasons.
Update the documentation and tests accordingly.
Fix usage of the words controller and id in the VMX handling code. Use
controller, bus and unit properly.
We already use the '-nodefaults' command line arg with QEMU to stop
it adding any default devices to guests. Unfortunately, QEMU will
load global config files from /etc/qemu that may also add default
devices. These aren't blocked by '-nodefaults', so we need to also
add the '-nodefconfig' arg to prevent that.
Unfortunately these global config files are also used to define
custom CPU models. So in blocking global hardware device addition
we also block definitions of new CPU models. Libvirt doesn't know
about these custom CPU models though, so it would never make use
of them anyway. Thus blocking them via -nodefconfig isn't a show
stopping problem. We would need to expand libvirt's own CPU model
XML database to support these instead.
* src/qemu/qemu_conf.c: Add '-nodefconfig' if available
* tests/qemuxml2argvdata/: Add '-nodefconfig' to all data files which
have '-nodefaults' present
This patch adds an optional XML attribute to a nwfilter rule to give the user control over whether the rule is supposed to be using the iptables state match or not. A rule may now look like shown in the XML below with the statematch attribute either having value '0' or 'false' (case-insensitive).

Red Hat BZ for this:
https://bugzilla.redhat.com/show_bug.cgi?id=603696
The virtio serial changes broke the test suite because they forgot
to add the new address attribute to the domain XML schema. The
xml2xml test also broke because the XML no longer roundtrips. This
is due to testing of auto-addition of <controller> elements. Split
that test case off into a separate XML file to avoid breakage
* docs/schemas/domain.rng: Allow port number for virtio serial addresses
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Revert to
a simple config to avoid breaking xml2xml test
* tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.xml,
tests/qemuxml2argvdata/qemuxml2argv-channel-virtio-auto.args: Add
complex test case for auto-controller addition for xml2argv test
* tests/qemuxml2argvtest.c: Add channel-virtio-auto test
The domain parsing code would auto-add a virtio serial controller
if it saw any virtio serial channel defined. Unfortunately it
always added a controller with index=0, even if the channel address
specified an index != 0. It only added one controller, even if
multiple controllers were referenced by channels. Finally, it let
the ports+vectors parameters initialize to zero instead of -1, which
prevented the controllers accepting any ports.
* src/conf/domain_conf.c: Initialize ports+vectors when adding
virtio serial controllers. Add all neccessary virtio serial
controllers, instead of hardcoding controller 0
* qemuxml2argvdata/qemuxml2argv-channel-virtio.args,
qemuxml2argvdata/qemuxml2argv-channel-virtio.xml: Expand to
test controller auto-add behaviour
To ensure that the device addressing scheme is stable across
hotplug/unplug, all virtio serial channels needs to have an
associated port number in their address. This is then specified
to QEMU using the nr=NNN parameter
* src/conf/domain_conf.c, src/conf/domain_conf.h: Parsing
for port number in vioserial address types.
* src/qemu/qemu_conf.c: Set 'nr=NNN' parameter with virtio
serial port number

'listen' isn't a valid qemu-dm option, as reported a long time ago here:

This patch parses the following two XML descriptions, one for
802.1Qbg and one for 802.1Qbh, and stores the data internally.
The actual triggering of the switch setup protocol has not been
implemented here but the relevant code to do that should go into
the functions associatePortProfileId() and disassociatePortProfileId().
<interface type='direct'>
<source dev='eth0.100' mode='vepa'/>
<model type='virtio'/>
<virtualport type='802.1Qbg'>
<parameters managerid='12' typeid='0x123456' typeidversion='1'

I'd suggest to use this patch as a base for triggering the setup
protocol with the 802.1Qb{g|h} switch.

- Addressing Daniel Berrange's comments:
- removing macvtap.h's dependency on domain_conf.h by
moving the virVirtualPortProfileDef structure into macvtap.h
and not passing virtDomainNetDefPtr to any functions in
macvtap.c
- Addressed most of Chris Wright's comments:
- indicating error in case virtualport XML node cannot be parsed
properly
- parsing hex and decimal numbers using virStrToLong_ui() with
parameter '0' for base
- tgifname (target interface name) variable wasn't necessary
to pass to openMacvtapTap function anymore
- assigning the virtual port data structure to the virDomainNetDef
only if it was previously parsed
- make sure that the error code returned by openMacvtapTap() is a negative n
in case the associatePortProfileId() function failed.
- renaming vsi in the XML to virtualport
- replace all occurrences of vsi in the source as well
- removing mode and MAC address parameters from the functions that
will communicate with the hareware diretctly or indirectly
- moving the associate and disassociate functions to the end of the
file for subsequent patches to easier make them generally available
for export
- passing the macvtap interface name rather than the link device since
this otherwise gives funny side effects when using netlink messages
where IFLA_IFNAME and IFLA_ADDRESS are specified and the link dev
all of a sudden gets the MAC address of the macvtap interface.
- Removing rc = -1 error indications in the case of 802.1Qbg|h setup in case
we wanted to use hook scripts for the setup and so the setup doesn't fail
here.
- if instance ID UUID is not supplied it will automatically be generated
- adapted schema to make instance ID UUID optional
- added test case
- parser and XML generator have been separated into their own
functions so they can be re-used elsewhere (passthrough case
for example)
- Adapted XML parser and generator support the above shown type
(802.1Qbg, 802.1Qbh).
- Adapted schema to above XML
- Adapted test XML to above XML
- Passing through the VM's UUID which seems to be necessary for
802.1Qbh -- sorry no host UUID
- adding virtual function ID to association function, in case it's
necessary to use (for SR-IOV)
Spurious / in a pool target path makes life difficult for apps using the
GetVolByPath, and doing other path based comparisons with pools. This
has caused a few issues for virt-manager users:
https://bugzilla.redhat.com/show_bug.cgi?id=494005https://bugzilla.redhat.com/show_bug.cgi?id=593565
Add a new util API which removes spurious /, virFileSanitizePath. Sanitize
target paths when parsing pool XML, and for paths passed to GetVolByPath.
v2: Leading // must be preserved, properly sanitize path=/, sanitize
away /./ -> /
v3: Properly handle starting ./ and ending /.
v4: Drop all '.' handling, just sanitize / for now.
Allow for a host UUID in the capabilities XML. Local drivers
will initialize this from the SMBIOS data. If a sanity check
shows SMBIOS uuid is invalid, allow an override from the
libvirtd.conf configuration file
* daemon/libvirtd.c, daemon/libvirtd.conf: Support a host_uuid
configuration option
* docs/schemas/capability.rng: Add optional host uuid field
* src/conf/capabilities.c, src/conf/capabilities.h: Include
host UUID in XML
* src/libvirt_private.syms: Export new uuid.h functions
* src/lxc/lxc_conf.c, src/qemu/qemu_driver.c,
src/uml/uml_conf.c: Set host UUID in capabilities
* src/util/uuid.c, src/util/uuid.h: Support for host UUIDs
* src/node_device/node_device_udev.c: Use the host UUID functions
* tests/confdata/libvirtd.conf, tests/confdata/libvirtd.out: Add
new host_uuid config option to test
* tests/nodeinfotest.c (linuxTestCompareFiles): Don't use
nodeinfo->member uninitialized. linuxNodeInfoCPUPopulate requires
that some of its nodeinfo members (including threads) be initialized
upon input. The nodeinfotest.c program lacked the initialization,
while the only other use (nodeGetInfo) did perform it.
It's not trivial to move the initialization into the function,
since nodeGetInfo sets at least one member after clearing the
buffer but before calling linuxNodeInfoCPUPopulate.
(gdb) p/x QEMUD_CMD_FLAG_VNET_HOST
$7 = 0xffffffff80000000
Oops - that meant we were incorrectly setting QEMU_CMD_FLAG_RTC_TD_HACK
for qemu-kvm-0.12.3 (and probably botching a few other settings as well).
Fixes Red Hat BZ#592070
* src/qemu/qemu_conf.h (QEMUD_CMD_FLAG_VNET_HOST): Avoid sign
extension.
* tests/qemuhelpdata/qemu-kvm-0.12.3: New file.
* tests/qemuhelptest.c (mymain): Add another case.
The max path length for unix sockets is pretty small (108, see man 7 unix).
If 'make check' is run from a directory that exceeds this, one of the tests
will fail, and in such a way that requires manually editting the test to
determine why.
There are certainly other ways to handle this, but I've chosen just to skip
the offending test if we will exceed the length limitation.
v2: Drop bashism, use test infrastructure to warn and skip
* tests/virsh-schedinfo: This test sets PATH internally, just in
case you're running it manually. Normally, the PATH setting from
tests/Makefile.am's TESTS_ENVIRONMENT is sufficient. Prepend the
correct directory, and take advantage of the PATH setting in one
more case.
For example, virsh -c test:///default schedinfo 1 --set P=k would
mistakenly exit successfully, giving no indication that it had failed
to set the scheduling parameter "P".
* tools/virsh.c (cmdSchedinfo): Diagnose an invalid --set j=k option,
rather than silently ignoring it.
* tests/virsh-schedinfo: New test for the above.
* tests/Makefile.am (test_scripts): Add it.

This patch adds support for the RARP protocol. This may be needed due to
qemu sending out a RARP packet (at least that's what it seems to want to
do even though the protocol id is wrong) when migration finishes and
we'd need a rule to let the packets pass.
Unfortunately my installation of ebtables does not understand -p RARP
and also seems to otherwise depend on strings in /etc/ethertype
translated to protocol identifiers. Therefore I need to pass -p 0x8035
for RARP. To generally get rid of the dependency of that file I switch
all so far supported protocols to use their protocol identifier in the
-p parameter rather than the string.
I am also extending the schema and added a test case.
changes from v1 to v2:
- added test case into patch
* virStorageEncryptionFormat is called from both
virDomainDiskDefFormat and virStorageVolTargetDefFormat. The proper
indentation in the generated XML depends on the caller. My earlier
patch to fix the incorrect indentation for the domain XML broke the
indentation for the storage XML. This patch adopts Laine's
suggestion of requring the caller of virStorageEncryptionFormat to
provide an unsigned int with the number of spaces the output should
be indented. The patch modifies both callers to provide the
additional argument.
* Add a regression test for the domain XML
* src/conf/domain_conf.c src/conf/storage_conf.c
src/conf/storage_encryption_conf.c src/conf/storage_encryption_conf.h:
change the indentation code
* tests/qemuxml2xmltest.c
tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.args
tests/qemuxml2argvdata/qemuxml2argv-encrypted-disk.xml: add a regression test
With this patch I want to enable hex number inputs in the filter XML. A
number that was entered as hex is also printed as hex unless a string
representing the meaning can be found.
I am also extending the schema and adding a test case. A problem with
the DSCP value is fixed on the way as well.
Changes from V1 to V2:
- using asHex boolean in all printf type of functions to select the
output format in hex or decimal format
The nodeinfotest was reliant on the host NUMA topology, but all
the test data files assumed 1 single NUMA node. This test thus
failed on any NUMA machine with > 1 node
* tests/nodeinfotest.c: Hardcode 1 single numa node
Fix invalid code generating in esx_vi_generator.py regarding deep copy
types that contain enum properties.
Add strptime and timegm to bootstrap.conf. Both are used to convert a
xsd:dateTime to calendar time.
Add a testcase of the xsd:dateTime conversion.
Extend tests to cover all SCSI controller types and document the
new type.
The lsisas1068 SCSI controller type was added in ESX 4.0. The VMX
parser reports an error when this controller type is present. This
makes virsh dumpxml fail for every domain that uses this controller
type.
This patch fixes this and adds lsisas1068 to the list of accepted
SCSI controller types.

This patch implements support for learning a VM's IP address. It uses
the pcap library to listen on the VM's backend network interface (tap)
or the physical ethernet device (macvtap) and tries to capture packets
with source or destination MAC address of the VM and learn from DHCP
Offers, ARP traffic, or first-sent IPv4 packet what the IP address of
the VM's interface is. This then allows to instantiate the network
traffic filtering rules without the user having to provide the IP
parameter somewhere in the filter description or in the interface
description as a parameter. This only supports to detect the parameter
IP, which is for the assumed single IPv4 address of a VM. There is not
support for interfaces that may have multiple IP addresses (IP
aliasing) or IPv6 that may then require more than one valid IP address
to be detected. A VM can have multiple independent interfaces that each
uses a different IP address and in that case it will be attempted to
detect each one of the address independently.
So, when for example an interface description in the domain XML has
looked like this up to now:
<interface type='bridge'>
<source bridge='mybridge'/>
<model type='virtio'/>
<filterref filter='clean-traffic'>
<parameter name='IP' value='10.2.3.4'/>
</filterref>
</interface>
you may omit the IP parameter:
<interface type='bridge'>
<source bridge='mybridge'/>
<model type='virtio'/>
<filterref filter='clean-traffic'/>
</interface>
Internally I am walking the 'tree' of a VM's referenced network filters
and determine with the given variables which variables are missing. Now,
the above IP parameter may be missing and this causes a libvirt-internal
thread to be started that uses the pcap library's API to listen to the
backend interface (in case of macvtap to the physical interface) in an
attempt to determine the missing IP parameter. If the backend interface
disappears the thread terminates assuming the VM was brought down. In
case of a macvtap device a timeout is being used to wait for packets
from the given VM (filtering by VM's interface MAC address). If the VM's
macvtap device disappeared the thread also terminates. In all other
cases it tries to determine the IP address of the VM and will then apply
the rules late on the given interface, which would have happened
immediately if the IP parameter had been explicitly given. In case an
error happens while the firewall rules are applied, the VM's backend
interface is 'down'ed preventing it to communicate. Reasons for failure
for applying the network firewall rules may that an ebtables/iptables
command failes or OOM errors. Essentially the same failure reasons may
occur as when the firewall rules are applied immediately on VM start,
except that due to the late application of the filtering rules the VM
now is already running and cannot be hindered anymore from starting.
Bringing down the whole VM would probably be considered too drastic.
While a VM's IP address is attempted to be determined only limited
updates to network filters are allowed. In particular it is prevented
that filters are modified in such a way that they would introduce new
variables.
A caveat: The algorithm does not know which one is the appropriate IP
address of a VM. If the VM spoofs an IP address in its first ARP traffic
or IPv4 packets its filtering rules will be instantiated for this IP
address, thus 'locking' it to the found IP address. So, it's still
'safer' to explicitly provide the IP address of a VM's interface in the
filter description if it is known beforehand.

This patch adds a relaxng nwfilter schema along with a test that
verifies all the test output XML against the schema. The input XMLs
contain a lot of intentional out-of-range values that make them fail the
schema verification, so I am not verifying against those.
A lot of syntax check rules have to be rewritten, but the
result is easier to maintain. I tested each syntax rule
by intentionally introducing a temporary violation of the rule.
Additionally, some false positives for unmarked_diagnostics
crept in, and an improved copyright_format test caught some bugs.
* .gnulib: Update to latest.
* cfg.mk (sc_prohibit_test_minus_ao): Delete, it was moved into
gnulib's maint.mk.

features indicated by each flag.
* tests/qemuhelptest.c: add appropriate flags into the masks for each test
* Fixes per feedback from Dan and Daniel
* Added test datafiles

The keys of entries in a VMX file are case insensitive. Both scsi0:1.fileName
and scsi0:1.filename are valid. Therefore, make the conf parser compare names
case insensitive in VMX mode to accept every capitalization variation.
Also add test cases for this.
* tests/test-lib.sh: "echo -n" is not portable. Use printf instead.
Remove unnecessary uses of "eval-in-subshell" (subshell is sufficient).
Remove uses of tests' -a operator; it is not portable.
Instead, use "test cond && test cond2".
* tests/schematestutils.sh: Replace use of test's -a.
This change only affects the output of tests that have an exact
multiple of 40 test cases. For example the domainschematest currently:
TEST: domainschematest
........................................ 40
........................................ 80
........................................ 120
........................................ 160
........................................ 200 OK
PASS: domainschematest
It outputs additional 40 spaces on the last line.
The domainschematest output is fixed by the change in test-lib.sh. The
change in testutils.c fixes this for tests written in C. Currently no
C test has an exact multiple of 40 test cases, but I checked it and
the same problem exists there.
This patch stops that in both cases.
* src/qemu/qemu_conf.c: add the ",readonly=on" for read-only disks
and also parse it back in qemuParseCommandLineDisk()

tests/qemuxml2argvdata/qemuxml2argv-disk-drive-readonly-disk.xml:
add a specific regression test
The current code for "nodeinfo" is pretty naive
about socket and thread information. To determine the
sockets, it just takes the number of cpus and divides
by the number of cores. For the thread count, it always
sets it to 1. With more recent Intel machines, however,
hyperthreading is again an option, meaning that these
heuristics no longer work and give bogus numbers. This
patch goes through /sys to get the additional
information so we properly report it.
Note that I had to edit the tests not to report on
socket and thread counts, since these are determined
dynamically now.
v2: As pointed out by Eric Blake, gnulib provides
count-one-bits (which is LGPLv2+). Use it instead
of a hand-coded popcnt.

Allow an arbitrary timezone with QEMU by setting the $TZ environment
variable when launching QEMU
* src/qemu/qemu_conf.c: Set TZ environment variable if a timezone
is requested
* tests/qemuxml2argvtest.c: Add test case for timezones
* tests/qemuxml2argvdata/qemuxml2argv-clock-france.xml,
tests/qemuxml2argvdata/qemuxml2argv-clock-france.args: Data

This allows QEMU guests to be started with an arbitrary clock
offset
The test case can't actually be enabled, since QEMU argv expects
an absolute timestring, and this will obviously change every
time the test runs :-( Hopefully QEMU will allow a relative
time offset in the future.
* src/qemu/qemu_conf.c, src/qemu/qemu_conf.h: Use the -rtc arg
if available to support variable clock offset mode
* tests/qemuhelptest.c: Add QEMUD_CMD_FLAG_RTC for qemu 0.12.1
* qemuxml2argvdata/qemuxml2argv-clock-variable.args,
qemuxml2argvdata/qemuxml2argv-clock-variable.xml,
qemuxml2argvtest.c: Test case, except we can't actually enable
it yet.
The daemon-conf test would fail on my system if there was a system libvirtd
running. In the course of troubleshooting that problem, I discovered that the
daemon-conf script would always fail if run by itself because it found the line:
\# that each "PARAMETER = VALUE" line in this file have the parameter
which it mistook for a line containing a parameter. I have changed the test to
avoid mistaking a line containing \"PARAMETER = VALUE\" for a parameter line.
The corrupted config tests turned out to be failing because the test daemon was
discovering the pid file from the running daemon and exiting before it processed
the test config file. Specifying the pid file for the corrupt config tests in
the same way as for the valid config test solved that problem.

Add support for virtio-serial by defining a new 'virtio' channel target type
and a virtio-serial controller. Allows the following to be specified in a
domain:
<controller type='virtio-serial' index='0' ports='16' vectors='4'/>
<channel type='pty'>
<target type='virtio' name='org.linux-kvm.port.0'/>
<address type='virtio-serial' controller='0' bus='0'/>

The virConnectPtr is no longer required for error reporting since
that is recorded in a thread local. Remove use of virConnectPtr
from all APIs in interface_conf.{h,c} and update all callers to
match
