There are two ways to request memory preallocation on cmd line:
-mem-prealloc and .prealloc attribute for a memory-backend-file.
However, as it turns out it's not safe to use both at the same
time. If -mem-prealloc is used then qemu will fully allocate the
memory (this is done by actually touching every page that has
been allocated). Then, if .prealloc=yes is specified,
mbind(flags = MPOL_MF_STRICT | MPOL_MF_MOVE) is called which:
a) has to (possibly) move the memory to a different NUMA node,
b) can have no effect when hugepages are in play (thus ignoring user
request to place memory on desired NUMA nodes).
Prefer -mem-prealloc as it is more backward compatible
compared to switching to "-numa node,memdev= + -object
memory-backend-file".

So far we have two arguments that we are passing to
qemuBuildMemoryBackendProps() and that are taken from domain
private data: @qemuCaps and @autoNodeset. In the next commit I
will use one more item from there. Therefore, instead of having
it as yet another argument to the function, pass pointer to the
private data object.
There is one change in qemuDomainAttachMemory() where previously
@autoNodeset was NULL but now is priv->autoNodeset (which may be
set). This is safe to do as @autoNodeset is advisory only.

Add a check during virDomainDefCompatibleDevice whether the
domain supports cold/hotplug of a memory module even though
this duplicates the qemuDomainDefValidateMemoryHotplug check.
Without this check, the cold/hot plug would fail on the

for max_memory > 0 would allow the subsequent hotplug check
to fail, but would cause coldplug to fail with the somewhat

The QEMU validation code for graphics has been in place for a while, but
because it is only executed from virDomainDeviceInfoIterateInternal, it
was never run, since the iterator expects the device to have boot info
which graphics don't have. The unfortunate side effect of this whole mess
was that a few capabilities were missing from the test suite (as commit
d8266ebe1 demonstrated with graphics-spice-invalid-egl-headless test),
which in turn meant that a few graphics tests which expected a failure
happily accepted any failure the test runtime returned which made them
succeed. The impact of this was that we then allowed to start a domain
with multiple OpenGL-enabled graphics devices.
This patch enables iteration over graphics devices. Unsurprisingly,
a few tests started to fail as a result, so fix those too.

Validation of domain devices is accomplished via a generic device
iterator which takes a callback, iterates over all kinds of supported
device types and invokes the callback on every single device. However,
there might be cases when we need to alter the behaviour of the

this patch introduces iterator flags.

This commit fixes a bug when you have multiple network settings defined.
Basically, if you set an IPv6 or IPv4 gateway, it carries on next
network settings. It is happening because the data is not being
initialized when a new network type is defined. So, the old data still
persists into the pointer. Another way to initialized the data was
introduced using memset() to avoid missing attributes from the struct.

If domain is killed with `xl destroy`, libvirt will not notice it and
still report the domain as running. Also trying to destroy the domain
through libvirt will fail. The only way to recover from such a situation
is to restart libvirt daemon. The problem is that even though libxl
report LIBXL_EVENT_TYPE_DOMAIN_DEATH, libvirt ignore it as all the
domain cleanup is done in a function actually destroying the domain. If
destroy is done outside of libvirt, there is no place where it would be
handled.
Fix this by doing domain cleanup in LIBXL_EVENT_TYPE_DOMAIN_DEATH too.
To avoid doing it twice, add a ignoreDeathEvent flag
libxlDomainObjPrivate, set when the domain death is triggered by libvirt
itself.

Commit 017dfa27d changed a few switch statements in the LXC code to

statement in virLXCControllerGetNICIndexes() to return an error status
for unsupported interface types, but it erroneously put type='direct'
on the list of unsupported types.
type='direct' (implemented with a macvlan interface) is supported on
LXC, but it's interface shouldn't be placed on the list of interfaces
given to CreateMachineWithNetwork() because the interface is put
inside the container, while CreateMachineWithNetwork() only wants to
know about the parent veths of veth pairs (the parent veth remains on

virLXCControllerGetNICIndexes() was deciding whether or not to add the
ifindex for an interface's ifname to the list of ifindexes sent to
CreateMachineWithNetwork based on the interface type stored in the
config. This would be incorrect in the case of <interface
type='network'> where the network was giving out macvlan interfaces
tied to a physical device (i.e. when the actual interface type was
"direct").
Instead of checking the setting of "net->type", we should be checking
the setting of virDomainNetGetActualType(net).
I don't think this caused any actual misbehavior, it was just
technically wrong.
