I am trying to use a qcow image with libvirt where the backing 'file' is a
qemu-nbd server. Unfortunately virDomainDiskDefForeachPath() assumes that
backingStore is always a real file so something like 'nbd:0:3333' is rejected
because a file with that name cannot be accessed. Note that I am not worried
about directly using nbd images. That would require a new disk type with XML
markup, etc. I only want it to be permitted as a backingStore
The following patch implements danpb's suggestion:
> I think I'm inclined to push the logic for skipping NBD one stage higher.
> I'd rather expect virStorageFileGetMetadata() to return all backing
> stores, even if not files. The virDomainDiskDefForeachPath() method
> should definitely ignore non-file backing stores though.
>
> So what I'm thinking is to extend the virStorageFileMetadata struct and
> just add a 'bool isFile' field to it. Default this field to true, unless
> you see the prefix of nbd: in which case set it to false. The
> virDomainDiskDefForeachPath() method can then skip over any backing
> store with isFile == false

xencapstest calls xenHypervisorMakeCapabilitiesInternal with conn == NULL
which calls xenDaemonNodeGetTopology with conn == NULL when a recent
enough Xen was detected (sys_interface_version >= SYS_IFACE_MIN_VERS_NUMA).
But xenDaemonNodeGetTopology insists in having conn != NULL and fails,
because it expects to be able to talk to an actual xend.
We cannot do that in a 'make check' test. Therefore, only call the xend
subdriver function when conn isn't NULL.

Using automated replacement with sed and editing I have now replaced all
occurrences of close() with VIR_(FORCE_)CLOSE() except for one, of
course. Some replacements were straight forward, others I needed to pay
attention. I hope I payed attention in all the right places... Please
have a look. This should have at least solved one more double-close
error.
This extends the SPICE XML to allow channel security options
<graphics type='spice' port='-1' tlsPort='-1' autoport='yes'>
<channel name='main' mode='secure'/>
<channel name='record' mode='insecure'/>
</graphics>
Any non-specified channel uses the default, which allows both
secure & insecure usage
* src/conf/domain_conf.c, src/conf/domain_conf.h,
src/libvirt_private.syms: Add XML syntax for specifying per
channel security options for spice.
* src/qemu/qemu_conf.c: Configure channel security with spice
QEMU crashes & burns if you try multiple Cirrus video cards, but
QXL copes fine. Adapt QEMU config code to allow multiple QXL

* src/qemu/qemu_conf.c: Support multiple QXL video cards
This extends the XML syntax for <graphics> to allow a password
expiry time to be set
eg
<graphics type='vnc' port='5900' autoport='yes' keymap='en-us' passwd='12345' passwdValidTo='2010-04-09T15:51:00'/>
The timestamp is in UTC.
* src/conf/domain_conf.h: Pull passwd out into separate struct
virDomainGraphicsAuthDef to allow sharing between VNC & SPICE
* src/conf/domain_conf.c: Add parsing/formatting of new passwdValidTo
argument
* src/opennebula/one_conf.c, src/qemu/qemu_conf.c, src/qemu/qemu_driver.c,
src/xen/xend_internal.c, src/xen/xm_internal.c: Update for changed
struct containing VNC password
In common with VNC, the QEMU driver configuration file is used
specify the host level TLS certificate location and a default
password / listen address
* src/qemu/qemu.conf: Add spice_listen, spice_tls,
spice_tls_x509_cert_dir & spice_password config params

tests/qemuxml2argvtest.c: Expand test case to cover driver
level configuration
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.
* src/qemu_conf.c, src/qemu_conf.h: Add SPICE flag. Check for
-spice availability. Format -spice arg for command line
* qemuhelptest.c: Add SPICE flag
* qemuxml2argvdata/qemuxml2argv-graphics-spice.args: Add <graphics>
for spice
* qemuxml2argvdata/qemuxml2argv-graphics-spice.xml: Add -spice arg
* qemuxml2argvtest.c: Add SPICE flag
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
for 2nd, 3rd, etc PCI devices for QXL
* src/qemu/qemu_conf.h: Flag for QXL support

case for generating spice args with RHEL6 kvm
This adds an element
<graphics type='spice' port='5903' tlsPort='5904' autoport='yes' listen='127.0.0.1'/>
This is the bare minimum that should be exposed in the guest
config for SPICE. Other parameters are better handled as per
host level configuration tunables

enumerations
There is no point in trying to fill params beyond the first error,
because when lxcDomainGetMemoryParameters returns -1 then the caller
cannot detect which values in params are valid.
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
Move existing routines about virSysinfoDef to an util module,
add a new entry point virSysinfoRead() to read the host values
with dmidecode
* src/conf/domain_conf.c src/conf/domain_conf.h src/util/sysinfo.c
src/util/sysinfo.h: move to a new module, add virSysinfoRead()
* src/Makefile.am: handle the new module build
* src/libvirt_private.syms: new internal symbols
* include/libvirt/virterror.h src/util/virterror.c: defined a new
error code for that module
* po/POTFILES.in: add new file for translations
the element has a mode attribute allowing only 3 values:
- emulate: use the smbios emulation from the hypervisor
- host: try to use the smbios values from the node
- sysinfo: grab the values from the <sysinfo> fields
* docs/schemas/domain.rng: extend the schemas
* src/conf/domain_conf.h: add the flag to the domain config
* src/conf/domain_conf.h: parse and serialize the smbios if present
* src/conf/domain_conf.h: defines a new internal type added to the
domain structure
* src/conf/domain_conf.c: parsing and serialization of that new type
During a shutdown/restart cycle libvirtd forgot the macvtap device name that it had created on behalf of a VM so that a stale macvtap device remained on the host when the VM terminated. Libvirtd has to actively tear down a macvtap device and it uses its name for identifying which device to tear down.
The solution is to not blank out the <target dev='...'/> completely, but only blank it out on VMs that are not active. So, if a VM is active, the device name makes it into the XML and is also being parsed. If a VM is not active, the device name is discarded.
virPipeReadUntilEOF is used to read the stdout of exec'ed
and this could fail to capture the full output and read only
1024 bytes.
The problem is that this is based on a poll loop, and in the
loop we read at most 1024 bytes per file descriptor, but we also
note in the loop if poll indicates that the process won't output
more than that on that fd by setting finished[i] = 1.
The simplest way is that if we read a full buffer make sure
finished[i] is still 0 because we will need another pass in the
loop.
The remoteIO() method has wierd calling conventions, where
it is passed a pre-allocated 'struct remote_call *' but
then free()s it itself, instead of letting the caller free().
This fixes those weird semantics
* src/remote/remote_driver.c: Sanitize semantics of remoteIO
method wrt to memory release
A couple of places in the text monitor were overwriting the
'ret' variable with a >= 0 value before success was actually
determined. So later error paths would not correctly return
the -1 value. The drive_add code was not checking for errors
like missing command
* src/qemu/qemu_monitor_text.c: Misc error handling fixes
NFS in root squash mode may prevent opening disk images to
determine backing store. Ignore errors in this scenario.
* src/security/security_selinux.c: Ignore open failures on disk

NFS does not support file labelling, so ignore this error
for stdin_path when on NFS.
* src/security/security_selinux.c: Ignore failures on labelling
stdin_path on NFS
* src/util/storage_file.c, src/util/storage_file.h: Refine
virStorageFileIsSharedFS() to allow it to check for a
specific FS type.
Commit 06f81c63eb attempted to make
QEMU driver ignore the failure to relabel 'stdin_path' if it was
on NFS. The actual result was that it ignores *all* failures to
label any aspect of the VM, unless stdin_path is non-NULL and
is not on NFS.
* src/qemu/qemu_driver.c: Treat all relabel failures as terminal
* src/xen/xend_internal.c (xenDaemonFormatSxpr): Hoist verify
outside of function to avoid a -Wnested-externs warning.

Add dump_image_format[] to qemu.conf and support compressed dump
at virsh dump. coredump compression is important for saving disk space
in an environment where multiple guests run.
In general, "disk space for dump" is specially allocated and will be
a dead space in the system. It's used only at emergency. So, it's better
to have both of save_image_format and dump_image_format. "save" is done
in scheduled manner with enough calculated disk space for it.
This code reuses some of save_image_format[] and supports the same format.
Changelog:
- modified libvirtd_qemu.aug
- modified test_libvirtd_qemu.aug
- fixed error handling of qemudSaveCompressionTypeFromString()
When we mount any cgroup without "-o devices", we will fail to start vms:
error: Failed to start domain vm1
error: Unable to deny all devices for vm1: No such file or directory
When we mount any cgroup without "-o cpu", we will fail to get schedinfo:
Scheduler : posix
error: unable to get cpu shares tunable: No such file or directory
We should only use the cgroup controllers which are mounted on host.
So I add virCgroupMounted() for qemuCgroupControllerActive()

https://bugzilla.redhat.com/show_bug.cgi?id=638285 - when migrating
a guest, it was very easy to provoke a race where an application
could query block information on a VM that had just been migrated
away. Any time qemu code obtains a job lock, it must also check
that the VM was not taken down in the time where it was waiting
for the lock.
* src/qemu/qemu_driver.c (qemudDomainSetMemory)

During virtual network startup, the iptables rule that allows tftp
traffic is only added if network->def->tftproot is non-empty, but when
the virtual network is destroyed, we had been unconditionally trying
to delete the rule. This was harmless, except that it created a bogus
error message.
This patch conditionalizes the delete command in the same manner that
the insert command is already conditionalized.
Commit 9bd3cce0d2 added virFork and
virDriverLoadModule to libvirt_private.syms, but virFork didn't have

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.
Older dash mistakenly truncates regular files when using <> redirection;
this kills our use of double dd to reduce storage overhead when
saving qemu images. But qemu insists on running a command through
/bin/sh, so we work around it by having qemu run $sh -c 'real command'
when we have a replacement $sh in mind.

When failing to start a virtual network, we have to cleanup,
tearing down any iptables rules. If the iptables rules were

network, don't squash the original error in cleanup
The network address was being set to 192.168.122.0 instead
of 192.168.122.0/24. Fix this by removing the unneccessary
'network' field from virNetworkDef and just pass the
network address and netmask into the iptables APIs directly.
* src/conf/network_conf.h, src/conf/network_conf.c: Remove
the 'network' field from virNEtworkDef.
* src/network/bridge_driver.c: Update for iptables API changes
* src/util/iptables.c, src/util/iptables.h: Require the

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.
The boot server IP address is optional, so it needs to be
checked before attempting to parse it.
* src/conf/network_conf.c: Don't parse NULL ip address for

Instead of storing the IP address string in virNetwork related
structs, store the parsed virSocketAddr. This will make it
easier to add IPv6 support in the future, by letting driver
code directly check what address family is present
* src/conf/network_conf.c, src/conf/network_conf.h,
src/network/bridge_driver.c: Convert to use virSocketAddr
in virNetwork, instead of char *.
* src/util/bridge.c, src/util/bridge.h,

* src/util/network.h: Add macros to determine if an address
is set, and what address family is set.
It is useful to know where the client is connecting from,
so include the socket address in probe data.

* src/util/network.h: Add sockaddr_un to virSocketAddr union
The inet_pton and inet_ntop functions are obsolete, replaced
by getaddrinfo+getnameinfo with the AI_NUMERICHOST flag set.
These can be accessed via the virSocket APIs.
The bridge.c code had methods for fetching the IP address of
a bridge which used inet_ntop. Aside from the use of inet_ntop
these methods are broken, because a NIC can have multiple
addresses and this only returns one address. Since the methods
are never used, just remove them.
* src/conf/network_conf.c, src/nwfilter/nwfilter_learnipaddr.c:
Replace inet_pton and inet_ntop with virSocket APIs
* src/util/bridge.c, src/util/bridge.h: Remove unused methods
which called inet_ntop.
The addrToString functionality is now available via the
virSocketFormatAddrFull method.
* daemon/remote.c, src/remote/remote_driver.c: Remove

The virSocketParse method was not doing any error reporting
which meant the true cause of the problem was lost. Remove

* src/util/network.c: Add error reporting to virSocketParse
* src/conf/domain_conf.c, src/conf/network_conf.c,
src/network/bridge_driver.c: Remove error reporting in
callers of virSocketParse
The getnameinfo() function is more flexible than inet_ntop()
avoiding the need to if/else the code based on socket family.
Also make it support UNIX socket addrs and allow inclusion
of a port (service) address. Finally do proper error reporting
via normal APIs.

src/qemu/qemu_conf.c: Fix error handling with virSocketFormat
* src/util/network.c: Rewrite virSocketFormat to use getnameinfo
and cope with UNIX socket addrs.
The nwIPAddress was simply a wrapper about virSocketAddr.
Just use the latter directly, removing all the extra field
de-references from code & helper APIs for parsing/formatting.
Also remove all the redundant casts from strong types to
void * and then immediately back to strong types.
* src/conf/nwfilter_conf.h: Remove nwIPAddress
* src/conf/nwfilter_conf.c, src/nwfilter/nwfilter_ebiptables_driver.c:
Update to use virSocketAddr and remove void * casts.
There was a typo in the IPv6 path of virSocketCheckNetmask which
caused it to never execute.
* src/util/network.c: s/AF_INET/AF_INET6/ in virSocketCheckNetmask
The virSocketParseAddr function was accepting any AF_* constant
and using that to set the ai_flags field in struct addrinfo.
This is invalid, since address families must go in the ai_family
field of the struct.
* src/util/network.c: Fix handling of address family
* src/conf/network_conf.c, src/network/bridge_driver.c: Pass
AF_UNSPEC instead of relying on it being 0.
Some operations on socket addresses need to know the length of
the sockaddr struct for the particular address family. This
info was being discarded when passing around virSocketAddr
instances. Turn it from a union into a struct containing
union+socklen_t fields, so length is always kept around.
* src/util/network.h: Add socklen_t field to virSocketAddr
* src/util/network.c, src/network/bridge_driver.c,
src/conf/domain_conf.c: Update to take account of new
struct definition.
If getnameinfo() with NI_NUMERICHOST set fails, there are no
grounds to expect inet_ntop to succeed, since these calls
are functionally equivalent. Remove useless inet_ntop code
in the getnameinfo() error path.
* daemon/remote.c, src/remote/remote_driver.c: Remove
calls to inet_ntop
* src/libvirt_private.syms: Sort by header name, then within
header, and drop duplicate virNetworkDefParseNode,
virFileLinkPointsTo and virXPathBoolean.
The QEMU 0.13 release is finally out and from testing in RHEL-6
we know that its JSON and netdev features are now good enough
for us to use by default.
* src/qemu/qemu_conf.c: Enable JSON + netdev for QEMU >= 0.13
There is no point in trying to fill params beyond the first error,
because when qemuDomainGetMemoryParameters returns -1 then the caller
cannot detect which values in params are valid.
This sets the process name to the same value as the Windows title,
but since the name is limited to 16 chars only this is kept as a
configuration option and turned off by default
* src/qemu/qemu.conf src/qemu/qemu_conf.[ch]: hceck for support in the
QEmu help output, add the option in qemu conf file and augment
qemudBuildCommandLine to add it if switched on
* src/qemu/libvirtd_qemu.aug src/qemu/test_libvirtd_qemu.aug: augment
the augeas lenses accordingly
* tests/qemuhelptest.c: cope with the extra flag being detected now
The libvirt_util.la library was mistakenly linked into libvirtd
directly. Since libvirt_util.la is already linked to libvirt.so,
this resulted in libvirtd getting two copies of the code and
more critically 2 copies of static global variables.
Testing in turn exposed a issue with loadable modules. The
gnulib replacement functions are not exported to loadable
modules. Rather than trying to figure out the name sof all
gnulib functions & export them, just linkage all loadable
modules against libgnu.la statically.
* daemon/Makefile.am: Remove linkage of libvirt_util.la
and libvirt_driver.la
* src/Makefile.am: Link driver modules against libgnu.la
* src/libvirt.c: Don't try to load modules which were
compiled out
* src/libvirt_private.syms: Export all other internal
symbols that are required by drivers
A more natural auditing point would perhaps be
SELinuxSetSecurityProcessLabel, but this happens in the child after root
permissions are dropped, so the kernel would refuse the audit record.
Most operations are audited at the libvirtd level; auditing in
src/libvirt.c would result in two audit entries per operation (one in
the client, one in libvirtd).
The only exception is a domain stopping of its own will (e.g. because
the user clicks on "shutdown" inside the interface). There can often be
no client connected at the time the domain stops, so libvirtd does not
have any virConnectPtr object on which to attach an event watch. This
patch therefore adds auditing directly inside the qemu driver (other
drivers are not supported).
Integrate with libaudit.so for auditing of important operations.
libvirtd gains a couple of config entries for auditing. By
default it will enable auditing, if its enabled on the host.
It can be configured to force exit if auditing is disabled
on the host. It will can also send audit messages via libvirt
internal logging API
Places requiring audit reporting can use the VIR_AUDIT
macro to report data. This is a no-op unless auditing is
enabled
* autobuild.sh, mingw32-libvirt.spec.in: Disable audit
on mingw
* configure.ac: Add check for libaudit

Note - this wrapping is completely mechanical; the old API will
function identically, since the new API validates that the exact
same flags are provided by the old API. On a per-driver basis,
it may make sense to have the old API pass a different set of flags,
but that should be done in the per-driver patch that implements
the full range of flag support in the new API.
