On LXC domain startup we have already called virDomainObjSetDefTransient
to fill vm->newDef.
There is no need to call virDomainLiveConfigHelperMethod which has the
ability to fill newDef if it's NULL.
A few functions using virDomainLiveConfigHelperMethod use the generic
name 'vmdef' to point to the persistent definition.
Use persistentDef and/or persistentDefCopy to make its purpose obvious.
Use udevHasDeviceProperty instead of udevGetStringProperty.
We do not need to copy the string since we do not need it.
Also add braces around the if body, since the change made
syntax check complain.
Two out of three callers free it right after converting it to a number.
Also change the comment at the beginning of the function, because
the comment inside the function told me to.
The wrapper adds an error message or a debug log.
Since we already log the properties we get from udev as strings,
there is no much use for the debug logs.
Open code the error message and delete the function.
Most of the code paths had to reset it to -1 and returning 0 was
only possible if we made it to the end of the function.
Initialize it to -1 and only set it to 0 if we reach the end, as we do
in most of libvirt code.
Remove the live attribute and mark the definition as transient
whether the domain is runing or not.
There were only two callers left calling with live=false:
* testDomainStartState, where the domain already is active
because we assigned vm->def->id just a few lines above the call
* virDomainObjGetPersistentDef, which now only calls
virDomainObjSetDefTransient for an active domain
Calling virDomainObjSetDefTransient with live=false is a no-op
on an inactive domain.
Only call it on an active domain, since this is the only place using
the live bool.
Commit 45ec297d from November 2010:
Make state driver device hotplug/update actually transient
added virDomainObjSetDefTransient calls to the domain startup
function in several drivers.
In November 2011, commit 8866eed:
Set aliases for LXC/UML console devices
added a call earlier in the startup function, without removing the
existing ones.
Also, in the UML driver it seems the function never did anything
useful - vm->def->id is set asynchronnously in umlNotifyEvent.
At the time of calling virDomainObjSetDefTransient with live=false,
vm->def->id was likely still -1, making the call a no-op.

Commit 5e54361c added virStoragePoolObjClearVols before refreshPool
to prevent duplicate volume entries.
However it is not needed here because we're not refreshing the pool yet,
just checking for the existence of the refresh callback.
The actual refresh is done via virStorageVolFDStreamCloseCb
in virStorageVolPoolRefreshThread, which already calls
virStoragePoolObjClearVols.
This test requests a read-only virtual FAT drive on the IDE bus.
Read-only IDE drives are unsupported, but libvirt only displays
the error if it has the QEMU_CAPS_DRIVE_READONLY capability.
Read-write FAT drives are also unsupported.
For some disk types (SD), we want to emit the syntax
we used for disks before -device was available even
if QEMU supports -device.
Use the qemuDiskBusNeedsDeviceArg helper to figure out
whether to use the old or new syntax.
QEMU needs access to the /dev/dri/render* device for
virgl to work.
Allow access to all /dev/dri/* devices for domains with
<video>
<model type='virtio' heads='1' primary='yes'>
<acceleration accel3d='yes'/>
</model>
</video>

Move filling out the default video (v)ram to DeviceDefPostParse.
This means it can be removed from virDomainVideoDefParseXML
and qemuParseCommandLine. Also, we no longer need to special case
VIR_DOMAIN_VIRT_XEN, since the per-driver callback gets called
before the generic one.
Commit 6879be48 moved adding of an implicit video device after XML
parsing. As a result, libxlDomainDeviceDefPostParse() is no longer
called to set the default vram when adding an implicit device.
Commit 6879be48 assumes virDomainVideoDefaultRAM() will set the
default vram, but it returns 0 if the domain virtType is
VIR_DOMAIN_VIRT_XEN. Attempting to start an HVM domain with vram=0
results in
error: unsupported configuration: videoram must be at least 4MB for CIRRUS
The default vram setting for Xen HVM domains depends on the device
model used (qemu-xen vs qemu-traditional), hence setting the
default is deferred to libxlDomainDeviceDefPostParse().
Call the device post-parse callback even for implicit video,
to fill out the default vram even for VIR_DOMAIN_VIRT_XEN.

In qemuDomainDefAddDefaultDevices we check for a non-NULL
def->os.machine for x86 archs, but not the others.
Moreover, the only caller - qemuDomainDefPostParse
already checks for it and even then it can happen only
if /etc/libvirt contains an XML without a machine type.
We do not need to propagate the exact return values
and the only possible ones are 0 and -1 anyway.
Remove the temporary variable and use the usual pattern:
if (f() < 0)
return -1;
In qemuHotplugCreateObjects, the ret variable was filled by
the value returned by qemuTestCapsCacheInsert.
If any of the functions after this assignment failed, we would still
return success.
Also adjust testCompareXMLToArgvHelper, where this change is just
cosmetic, because the value was overwritten right away.
The address assigning code might add new pci bridges.
We need them to have an alias when building the command line.
In real word usage, this is not a problem because all the code
paths already call qemuDomainAssignAddresses. However moving
this call lets us remove one extra call from qemuxml2argvtest.
It is only used for failed address allocation
Since we already have FLAG_EXPECT_FAILURE, use that instead.
Also unify the output to print the whole log buffer instead
of just the last error message.
After removing qemuBuildCommandLineCallbacks, testutilsqemu.h does not
need to include qemu_command.h.
Include just qemu_conf.h here and qemu_domain_address.h in files that
need it.
Essentially revert commit 3a6204c which added these to allow the test
suite to pass without depending on the host system state.
Since commit 4b527c1 we already mock virSCSIDeviceGetSgName, so these
callbacks are useless.
