Since now we have fixed domain UUID for test driver, defining
a domain with different name but same UUID doesn't work any
more. This patch delete the UUID from the dumped XML so that
it could be generated.
A "ide-drive" device can be either a hard disk or a CD-ROM,
if there is ",media=cdrom" specified for the backend, it's
a CD-ROM, otherwise it's a hard disk.
Upstream qemu splitted "ide-drive" into "ide-hd" and "ide-cd"
since commit 1f56e32, and ",media=cdrom" is not required for
ide-cd anymore. "ide-drive" is still supported for backwards
compatibility, but no doubt we should go foward.
A "scsi-disk" device can be either a hard disk or a CD-ROM,
if there is ",media=cdrom" specified for the backend, it's
a CD-ROM, otherwise it's a hard disk.
But upstream qemu splitted "scsi-disk" into "scsi-hd" and
"scsi-cd" since commit b443ae, and ",media=cdrom" is not
required for scsi-cd anymore. "scsi-disk" is still supported
for backwards compatibility, but no doubt we should go
foward.

When building on Fedora 17 (which uses gcc 4.7.0) with -O0 in CFLAGS,
three of the tests failed to compile.
cputest.c and qemuxml2argvtest.c had non-static structs defined
inside the macro that was being repeatedly invoked. Due to some so-far
unidentified change in gcc, the stack space used by variables defined
inside { } is not recovered/re-used when the block ends, so all these
structs have become additive (this is the same problem worked around
in commit cf57d345b). Fortunately, these two files could be fixed with
a single line addition of "static" to the struct definition in the
macro.
virnettlscontexttest.c was a bit different, though. The problem structs
in the do/while loop of macros had non-constant initializers, so it
took a bit more work and piecemeal initialization instead of member
initialization to get things to be happy.
In an ideal world, none of these changes should be necessary, but not
knowing how long it will be until the gcc regressions are fixed, and
since the code is just as correct after this patch as before, it makes
sense to fix libvirt's build for -O0 while also reporting the gcc
problem.
This bug resolves https://bugzilla.redhat.com/show_bug.cgi?id=810100
rpm builds for i686 were failing with a segfault in
networkxml2argvtest. Running under valgrind showed that a region of
memory was being referenced after it had been freed (as the result of
realloc - see the valgrind report in the BZ).
The problem (in replaceTokens() - added in commit 22ec60, meaning this
bug was in 0.9.10 and 0.9.11) was that the pointers token_start and
token_end were being computed based on the value of *buf, then *buf
was being realloc'ed (potentially moving it), then token_start and
token_end were used without recomputing them to account for movement
of *buf.
The solution is to change the code so that token_start and token_end
are offsets into *buf rather than pointers. This way there is only a
single pointer to the buffer, and nothing needs readjusting after a
realloc. (You may note that some uses of token_start/token_end didn't
need to be changed to add in "*buf +" - that's because there ended up
being a +*buf and -*buf which canceled each other out).
DV gets the credit for finding this bug and pointing out the valgrind
report.
Some of the test suites use fprintf with format specifiers
that are not supported on Win32 and are not fixed by gnulib.

XenD-3.1 introduced managed domains. HV-domains have rtc_timeoffset
(hgd24f37b31030 from 2007-04-03), which tracks the offset between the
hypervisors clock and the domains RTC, and is persisted by XenD.
In combination with localtime=1 this had a bug until XenD-3.4
(hg5d701be7c37b from 2009-04-01) (I'm not 100% sure how that bug
manifests, but at least for me in TZ=Europe/Berlin I see the previous
offset relative to utc being applied to localtime again, which manifests
in an extra hour being added)
XenD implements the following variants for clock/@offset:
- PV domains don't have a RTC → 'localtime' | 'utc'
- <3.1: no managed domains → 'localtime' | 'utc'
- ≥3.1: the offset is tracked for HV → 'variable'
due to the localtime=1 bug → 'localtime' | 'utc'
- ≥3.4: the offset is tracked for HV → 'variable'
Current libvirtd still thinks XenD only implements <clock offset='utc'/>
and <clock offset='localtime'/>, which is wrong, since the semantic of
'utc' and 'localtime' specifies, that the offset will be reset on
domain-restart, while with 'variable' the offset is kept. (keeping the
offset over "virsh edit" is important, since otherwise the clock might
jump, which confuses certain guest OSs)
xendConfigVersion was last incremented to 4 by the xen-folks for
xen-3.1.0. I know of no way to reliably detect the version of XenD
(user space tools), which may be different from the version of the
hypervisor (kernel) version! Because of this only the change from
'utc'/'localtime' to 'variable' in XenD-3.1 is handled, not the buggy
behaviour of XenD-3.1 until XenD-3.4.
For backward compatibility with previous versions of libvirt Xen-HV
still accepts 'utc' and 'localtime', but they are returned as 'variable'
on the next read-back from Xend to libvirt, since this is what XenD
implements: The RTC is NOT reset back to the specified time on next
restart, but the previous offset is kept.
This behaviour can be turned off by adding the additional attribute
adjustment='reset', in which case libvirt will report an error instead
of doing the conversion. The attribute can also be used as a shortcut to
offset='variable' with basis='...'.
With these changes, it is also necessary to adjust the xen tests:
"localtime = 0" is always inserted, because otherwise on updates the
value is not changed within XenD.
adjustment='reset' is inserted for all cases, since they're all <
XEND_CONFIG_VERSION_3_1_0, only 3.1 introduced persistent
rtc_timeoffset.
Some statements change their order because code was moved around.

Since Xen 3.1 the clock=variable semantic is supported. In addition to
qemu/kvm Xen also knows about a variant where the offset is relative to
'localtime' instead of 'utc'.
Extends the libvirt structure with a flag 'basis' to specify, if the
offset is relative to 'localtime' or 'utc'.
Extends the libvirt structure with a flag 'reset' to force the reset
behaviour of 'localtime' and 'utc'; this is needed for backward
compatibility with previous versions of libvirt, since they report
incorrect XML.

numad is an user-level daemon that monitors NUMA topology and
processes resource consumption to facilitate good NUMA resource
alignment of applications/virtual machines to improve performance
and minimize cost of remote memory latencies. It provides a
pre-placement advisory interface, so significant processes can
be pre-bound to nodes with sufficient available resources.
More details: http://fedoraproject.org/wiki/Features/numad
"numad -w ncpus:memory_amount" is the advisory interface numad
provides currently.
This patch add the support by introducing a new XML attribute
for <vcpu>. e.g.
<vcpu placement="auto">4</vcpu>
<vcpu placement="static" cpuset="1-10^6">4</vcpu>
The returned advisory nodeset from numad will be printed
in domain's dumped XML. e.g.
<vcpu placement="auto" cpuset="1-10^6">4</vcpu>
If placement is "auto", the number of vcpus and the current
memory amount specified in domain XML will be used for numad
command line (numad uses MB for memory amount):
numad -w $num_of_vcpus:$current_memory_amount / 1024
The advisory nodeset returned from numad will be used to set
domain process CPU affinity then. (e.g. qemuProcessInitCpuAffinity).
If the user specifies both CPU affinity policy (e.g.
(<vcpu cpuset="1-10,^7,^8">4</vcpu>) and placement == "auto"
the specified CPU affinity will be overridden.
Only QEMU/KVM drivers support it now.
See docs update in patch for more details.
If there is a disk file with a comma in the name, QEmu expects a double
comma instead of a single one (e.g., the file "virtual,disk.img" needs
to be specified as "virtual,,disk.img" in QEmu's command line). This
patch fixes libvirt to work with that feature. Fix RHBZ #801036.

We found few more AMD-specific features in cpu64-rhel* models that
made it impossible to start qemu guest on Intel host (with this
setting) even though qemu itself starts correctly with them.
This impacts one test, thus the fix in tests/cputestdata/.
One of the recent commits introduced support for
spice agent-mouse. However, test for this feature
require some tweaking: pass QEMU_CAPS_CHARDEV_SPICEVMC |
QEMU_CAPS_NODEFCONFIG and add "-vga cirrus".
If user hasn't supplied any tlsPort we default to setting it

line we test it against -1 which is obviously wrong.
In the past, we have created some virsh options with less-than-stellar
names. For back-compat reasons, those names must continue to parse,
but we don't want to document them in help output. This introduces
a new option type, an alias, which points to a canonical option name
later in the option list.

The test domain allows <memory>0</memory>, but the RNG was stating
that memory had to be at least 4096000 bytes. Hypervisors should

Disk manufacturers are fond of quoting sizes in powers of 10,
rather than powers of 2 (after all, 2.1 GB sounds larger than
2.0 GiB, even though the exact opposite is true). So, we might
as well follow coreutils' lead in supporting three types of
suffix: single letter ${u} (which we already had) and ${u}iB
for the power of 2, and ${u}B for power of 10.
Additionally, it is impossible to create a file with more than
2**63 bytes, since off_t is signed (if you have enough storage
to even create one 8EiB file, I'm jealous). This now reports
failure up front rather than down the road when the kernel
finally refuses an impossible size.

Make it obvious to 'dumpxml' readers what unit we are using,
since our default of KiB for memory (1024) differs from qemu's

$ find tests/*data tests/*out -name '*.xml' | \
xargs sed -i 's/<\(capacity\|allocation\|available\)>/<\1 unit='"'bytes'>/"
followed by a few fixes for the stragglers.
Note that with this patch, the RNG for <memory> still forbids
validation of anything except unit='KiB', since the code silently
ignores the attribute; a later patch will expand <memory> to allow
scaled input in the code and update the RNG to match.

This patch makes sure that each network device ("interface") of
type='hostdev' appears on both the hostdevs list and the nets list of
the virDomainDef, and it modifies the qemu driver startup code so that
these devices will be presented to qemu on the commandline as hostdevs
rather than as network devices.
It does not add support for hotplug of these type of devices, or code
to honor the <mac address> or <virtualport> given in the config (both
of those will be done in separate patches).
Once each device is placed on both lists, much of what this patch does
is modify places in the code that traverse all the device lists so
that these hybrid devices are only acted on once - either along with
the other hostdevs, or along with the other network interfaces. (In
many cases, only one of the lists is traversed / a specific operation
is performed on only one type of device. In those instances, the code
can remain unchanged.)
There is one special case - when building the commandline, interfaces
are allowed to proceed all the way through
networkAllocateActualDevice() before deciding to skip the rest of
netdev-specific processing - this is so that (once we have support for
networks with pools of hostdev devices) we can get the actual device
allocated, then rely on the loop processing all hostdevs to generate
the correct commandline.
(NB: <interface type='hostdev'> is only supported for PCI network
devices that are SR-IOV Virtual Functions (VF). Standard PCI[e] and
USB devices, and even the Physical Functions (PF) of SR-IOV devices
can only be assigned to a guest using the more basic <hostdev> device
entry. This limitation is mostly due to the fact that non-SR-IOV
ethernet devices tend to lose mac address configuration whenever the
card is reset, which happens when a card is assigned to a guest;
SR-IOV VFs fortunately don't suffer the same problem.)
This is the new interface type that sets up an SR-IOV PCI network
device to be assigned to the guest with PCI passthrough after
initializing some network device-specific things from the config
(e.g. MAC address, virtualport profile parameters). Here is an example
of the syntax:
<interface type='hostdev' managed='yes'>
<source>
<address type='pci' domain='0' bus='0' slot='4' function='3'/>
</source>
<mac address='00:11:22:33:44:55'/>
<address type='pci' domain='0' bus='0' slot='7' function='0'/>
</interface>
This would assign the PCI card from bus 0 slot 4 function 3 on the
host, to bus 0 slot 7 function 0 on the guest, but would first set the
MAC address of the card to 00:11:22:33:44:55.
NB: The parser and formatter don't care if the PCI card being
specified is a standard single function network adapter, or a virtual
function (VF) of an SR-IOV capable network adapter, but the upcoming
code that implements the back end of this config will work *only* with
SR-IOV VFs. This is because modifying the mac address of a standard
network adapter prior to assigning it to a guest is pointless - part
of the device reset that occurs during that process will reset the MAC
address to the value programmed into the card's firmware.
Although it's not supported by any of libvirt's hypervisor drivers,
usb network hostdevs are also supported in the parser and formatter
for completeness and consistency. <source> syntax is identical to that
for plain <hostdev> devices, except that the <address> element should
have "type='usb'" added if bus/device are specified:
<interface type='hostdev'>
<source>
<address type='usb' bus='0' device='4'/>
</source>
<mac address='00:11:22:33:44:55'/>
</interface>
If the vendor/product form of usb specification is used, type='usb'
is implied:
<interface type='hostdev'>
<source>
<vendor id='0x0012'/>
<product id='0x24dd'/>
</source>
<mac address='00:11:22:33:44:55'/>
</interface>
Again, the upcoming patch to fill in the backend of this functionality
will log an error and fail with "Unsupported Config" if you actually
try to assign a USB network adapter to a guest using <interface
type='hostdev'> - just use a standard <hostdev> entry in that case
(and also for single-port PCI adapters).
No thanks to 64-bit windows, with 64-bit pid_t, we have to avoid
constructs like 'int pid'. Our API in libvirt-qemu cannot be
changed without breaking ABI; but then again, libvirt-qemu can
only be used on systems that support UNIX sockets, which rules
out Windows (even if qemu could be compiled there) - so for all
points on the call chain that interact with this API decision,
we require a different variable name to make it clear that we
audited the use for safety.
Adding a syntax-check rule only solves half the battle; anywhere
that uses printf on a pid_t still needs to be converted, but that

For any disk controller model which is not "lsilogic", the command
line will be like:
-drive file=/dev/sda,if=none,id=drive-scsi0-0-3-0,format=raw \
-device scsi-disk,bus=scsi0.0,channel=0,scsi-id=3,lun=0,i\
drive=drive-scsi0-0-3-0,id=scsi0-0-3-0
The relationship between the libvirt address attrs and the qdev
properties are (controller model is not "lsilogic"; strings
inside <> represent libvirt adress attrs):
bus=scsi<controller>.0
channel=<bus>
scsi-id=<target>
lun=<unit>
* src/qemu/qemu_command.h: (New param "virDomainDefPtr def"
for function qemuBuildDriveDevStr; new param "virDomainDefPtr
vmdef" for function qemuAssignDeviceDiskAlias. Both for
virDomainDiskFindControllerModel's use).
* src/qemu/qemu_command.c:
- New param "virDomainDefPtr def" for qemuAssignDeviceDiskAliasCustom.
For virDomainDiskFindControllerModel's use, if the disk bus is "scsi"
and the controller model is not "lsilogic", "target" is one part of
the alias name.
- According change on qemuAssignDeviceDiskAlias and qemuBuildDriveDevStr
* src/qemu/qemu_hotplug.c:
- Changes to be consistent with declarations of qemuAssignDeviceDiskAlias
qemuBuildDriveDevStr, and qemuBuildControllerDevStr.
* tests/qemuxml2argvdata/qemuxml2argv-pseries-vio-user-assigned.args,
tests/qemuxml2argvdata/qemuxml2argv-pseries-vio.args: Update the
generated command line.
* src/conf/domain_conf.h: Add new member "target" to struct
_virDomainDeviceDriveAddress.
* src/conf/domain_conf.c: Parse and format "target"
* Lots of tests (.xml) in tests/domainsnapshotxml2xmlout,
tests/qemuxml2argvdata, tests/qemuxml2xmloutdata, and
tests/vmx2xmldata/ are modified for newly introduced
attribute "target" for address of "drive" type.
