Now that we choose the GIC version based on hardware features when
no <gic/> element has been provided, we need a way to fake the GIC
capabilities of the host.

Update the qemuxml2argv and qemuxml2xml tests to allow this.

For use in the test suite.

When the <gic/> element in not present in the domain XML, use the
domain capabilities to figure out what GIC version is usable and
choose that one automatically.

This allows guests to be created on hardware that only supports
GIC v3 without having to update virt-manager and similar tools.

Keep using the default GIC version if the <gic/> element has been
added to the domain XML but no version has been specified, as not
to break existing guests.

This utility function extracts some of the logic from
virQEMUCapsFillDomainFeatureGICCaps() so that it can be used
in a different context.

The INPLACE variants of the VIR_APPEND macros cannot fail and they are
inherently quiet.

It was just a useless wrapper around VIR_APPEND_ELEMENT*.

According to current xl.cfg docs and xl codes, it uses type=vif
instead of type=netfront.

Currently after domxml-to-native, libvirt xml model=netfront will be
converted to xl type=netfront. This has no problem before, xen codes
for a long time just check type=ioemu, if not, set type to _VIF.

Since libxl uses parse_nic_config to avoid duplicate codes, it
compares 'type=vif' and 'type=ioemu' for valid parameters, others
are considered as invalid, thus we have problem with type=netfront
in xl config file.
 #xl create sles12gm-hvm.orig
 Parsing config from sles12gm-hvm.orig
 Invalid parameter `type'.

Correct the conversion in libvirt, so that it matchs libxl codes
and also xl.cfg.

Trivially return 1, since bhyve is considered a local connection that
should not be vulnerable to eavesdropping.

Being a local connection, bhyve does not support encryption. Therefore
trivially return 0.

It was only needed for rpm versions that are much older than our
minimally supported distro

This reverts commit 071fe092.
It was committed by a mistake and correct patch was committed
earlier as baad90fb.

If we exceed the timeout waiting for the tray status to change,
we don't report an error. Fix it

This is just a trivial cosmetic change, throughout all the APIs the argument
is called conn as from 'connection', having 'dmn' at just this single place
might look odd, so better change it now when the interface is still explicitly
disabled and we still have the ability to alter the signatures and public
names before officially enabling it.

SDK handles empty cdroms all right. We just need to
pass "" instead of NULL (not setting is good too).

However we can get problems here. Disk detaching treats source
as ids. Fortunately disk detaching is not supported for cdroms
yet and for hard disks we can not get empty source - this is prohibitited
by xml parsing code.

Current version of the function does not check format of cdroms at all.
At the same time prlsdkGetDiskInfo give hints that cdroms always
have format VIR_STORAGE_FILE_RAW. So fix vzCheckUnsupportedDisks.

About structure of checks. As we don't have means to store format
in SDK we always have only one format in every situation. So instead
of setting boolean let's get allowed format instead and finally compare
it to the requested. This structure of checks seems stable to me
because we have only one format in every situation.

VIR_STORAGE_FILE_AUTO can not be set from xml description.
At the same time we don't set disks format to this value
as for example qemu does. Thus this we can never get this
value in format.

We support omitting listen attribute of graphics element so we should
also support omitting address attribute of listen element.  This patch
also updates libvirt to always add a listen element into domain XML
except for VNC graphics if socket attribute is specified.

Move the compatibility code out of virDomainGraphicsListensParseXML()
into virDomainGraphicsListenDefParseXML().  This also fixes a small
inconsistency between the code and error message itself.

Before this patch we would search first listen element that is
type='address' to validate listen and address attributes. After this
patch we always take the first listen element regardless of the type.

This shouldn't break anything since all drivers supports only one
listen.

Commit 82ba4110 made possible to use direct mapped iSCSI
volumes in qemu as disk sources but didn't remove the define time check.

Rework the check by simplifying the condition and allow any volumes to
be used with disk type='lun'.

The only QEMU versions that don't have such capability are <0.11,
which we no longer support anyway

The only QEMU versions that don't have such capability are <0.12,

Additionally, this solves the issue of some QEMU binaries being

Commit id 'f9edcfa4' added cookie manipulation for libxl; however, some
cookie crumb cleanup was missed. Found by Coverity.

In libxlDomainMigrationBegin, the cookie is allocated and baked; however,
the mig ingredients weren't cleaned up.

In libxlDomainMigrationPrepare, when the 'mig' cookie is added to the
args, set the 'mig = NULL'; otherwise, other failure paths between when
the code ate the cookie data and when it was added to args would fail
to clean up the crumbs.

Recent adjustments to the code produced a litany of coverity false
positives, but only because the "standard" procedure of setting a
variable to NULL after it was assigned to something else and keeping
the *Free/*FREE call in the cleanup path wasn't kept. So this patch
makes those adjustments (assign variable to NULL and remove the if
'ret < 0' condition to clean it up).

bhyve connections are local, and a "connection will be classed as alive
if it is [...] local".

-name guest= is the explicit parameter for passing a VM name. Using
it is required to allow a VM with an '=' in the name

https://bugzilla.redhat.com/show_bug.cgi?id=1276485

After this, a default virt-manager VM will startup with a comma
in the VM name:

https://bugzilla.redhat.com/show_bug.cgi?id=639926

This path can be dependent on the VM libdir, which contains its name

Need to convert the local function to virBuffer usage, so we
can use qemuBufferEscapeComma

This isn't sufficient on its own, since the VM name is used for things
like monitor paths, which we don't escape yet

Centralize the magic invocation for escaping commas on the qemu
command line, and document it a bit

QEMU_CAPS_DEVICE is always set nowadays, so drop code that depends
on not-DEVICE
