needs to also support a Unix socket, for retrieving the backup from
the same host. Support this by plumbing virStorageNetHostDef through
the monitor calls, since that is a nice reusable struct that can track
both TCP and Unix sockets.
Update qemumonitorjsontest to verify both forms of the QMP command.

Ever since the feature was introduced with commit 0f8e7ae33a,
it has contained a logic error in that it attempted to use a NUMA
node map where a CPU map was expected.
Because of that, guests using <numatune> might fail to start:
# virsh start guest
error: Failed to start domain guest
error: cannot set CPU affinity on process 40055: Invalid argument
This was particularly easy to trigger on POWER 8 machines, where
secondary threads always show up as offline in the host: having
<numatune>
<memory mode='strict' placement='static' nodeset='1'/>
</numatune>
in the guest configuration, for example, would result in libvirt
trying to set the process affinity so that it would prefer
running on CPU 1, but since that's a secondary thread and thus
shows up as offline, the operation would fail, and so would
starting the guest.
Use the newly introduced virNumaNodesetToCPUset() to convert the
NUMA node map to a CPU map, which in the example above would be
48,56,64,72,80,88 - a valid input for virProcessSetAffinity().

When migrating a domain with invtsc CPU feature enabled, the TSC
frequency of the destination host must match the frequency used when the
domain was started on the source host or the destination host has to
support TSC scaling.
If the frequencies do not match and the destination host does not
support TSC scaling, QEMU will fail to set the right TSC frequency when
starting vCPUs on the destination and thus migration will fail. However,
this is quite late since both host might have spent significant time
transferring memory and perhaps even storage data.
By adding the check to libvirt we can let migration fail before any data
starts to be sent over. If for some reason libvirt is unable to detect
the host's TSC frequency or scaling support, we'll just let QEMU try and
the migration will either succeed or fail later.
Luckily, we mandate TSC frequency to be explicitly set in the domain XML
to even allow migration of domains with invtsc. We can just check
whether the requested frequency is compatible with the current host
before starting QEMU.

An active domain stores both current and new definitions. The current

(vm->newDef) stores the config XML. In an inactive domain, only the
config XML is persistent, and it's saved in vm->def.
The revert operation uses the virDomainObjAssignDef() to set the

inactive XML after a blockjob as the variable which was determining
whether to do so is cleared right before. Thus even if we correctly
modify the inactive state it will be rolled back when libvirtd is

When a vhost scsi device is hotplugged virt-aa-helper is called to

For example the config:
<hostdev mode='subsystem' type='scsi_host' managed='no'>
<source protocol='vhost' wwpn='naa.50014059de6fba4f'/>
</hostdev>
Will call it to add:
/sys/kernel/config/target/vhost//naa.50014059de6fba4f
But in general /sys paths are filtered in virt-aa-helper.c:valid_path
To allow the path used for vhost-scsi we need to add it to the list of

Qemu dropped cpu features for osxsave and ospke [1][2].
The reason for the instant removal is that those features were never
configurable as discussed in [3].
Fortunately the use cases adding those flags in the past are rare, but
they exist. One that I identified are e.g. older virt-install when used
with --cpu=host-model and there always could be the case of a user
adding it to the guest xml.
This triggers an issue like:
qemu-system-x86_64: can't apply global Broadwell-noTSX-x86_64-
cpu.osxsave=on: Property '.osxsave' not found
Ensure that this does no more break spawning newer qemu versions by

This function gets snapshot XML (provided by used) as an
argument. It parses it into a local variable @def and then sets
some more members (e.g. it creates a copy of live domain XML).
Then it proceeds to checking if snapshot XML is valid (e.g. it
contains as many disks as currently in the domain). If this fails
then the control jumps to endjob label and subsequently return
from the function. This is where AUTOFREE function for @def is
ran. Well, because the code says to run plain VIR_FREE() we leak
some memory because @def is actually an object and therefore
it should have been declared as AUTOUNREF.

Since it does not matter where we add the entry and it's usually more

If the current QEMU guest can't wake up from suspend properly,
and we are able to determine that, avoid suspending the guest
at all. To be able to determine this support, QEMU needs to
implement the 'query-current-machine' QMP call. This is reflected
by the QEMU_CAPS_QUERY_CURRENT_MACHINE cap.
If the cap is enabled, a new function qemuDomainProbeQMPCurrentMachine
is called. This is wrapper for qemuMonitorGetCurrentMachineInfo,
where the 'wakeup-suspend-support' flag is retrieved from
'query-current-machine'. If wakeupSuspendSupport is true,
proceed with the regular flow of qemuDomainPMSuspendForDuration.
The absence of QEMU_CAPS_QUERY_CURRENT_MACHINE indicates that
we're dealing with a QEMU version older than 4.0 (which implements
the required QMP API). In this case, proceed as usual with the
suspend logic of qemuDomainPMSuspendForDuration, since we can't
assume whether the guest has support or not.

DMA zone available on the NUMA node. Well, while the work around
might stopped libvirt tickling the KVM bug it also caused a bug
on libvirt side: if there is not enough memory on configured NUMA
node(s) then any attempt to start a domain must fail. Because of
the way we play with guest memory domains can start just happily.
The solution is to move the child we've just forked into emulator
cgroup, set up cpuset.mems and exec() qemu only after that.
This basically reverts 7e72ac7878 which was a workaround
for kernel bug. This bug was apparently fixed because I've tested
this successfully with recent kernel.

This reverts commit f1d6585300.
Turns out, this caused a regression. There is this (perhaps less
known) semantic of virDomainAttachDevice() where if the device
the API is trying to attach is a CDROM/floppy that is already in
the domain the attach request is handled as 'change the media in
the drive'.
We have a better fix anyways.

Ports allocated on virtual networks with type=nat|route|open all get
given an actual type of 'network'.
Only ports in networks with type=bridge use an actual type of 'bridge'.
This distinction makes little sense since the virtualization drivers
will treat both actual types in exactly the same way, as they're all
just bridge devices a VM needs to be connected to.
This doesn't affect user visible XML since the "actual" device XML
is internal only, but we need code to convert the data upgrades.

Move the non-deterministic code that sets snapshot properties
independently of what the incoming XML described to instead live in a
default post-parse function common to virDomainMoment (as checkpoints
will also reuse it in later patches). This patch is just code motion,
with no difference to any callers; but the next patch will further
refactor things to allow for a per-driver override, used by the
testsuite to perform deterministic post-parse actions for better
coverage of parser/formatter code.
Note that the post-parse code is intentionally not run during a
snapshot redefine, since that code path already requires a valid
snapshot name and creation time from the XML.

None of the existing drivers actually use the 0-valued 'nostate'
snapshot state; rather, it was a fluke of implementation. In fact,
some drivers, like qemu, actively reject 'nostate' as invalid during a
snapshot redefine. Normally, a driver computes the state post-parse
from the current domain, and thus virDomainSnapshotGetXMLDesc() will
never expose the state. However, since the testsuite lacks any
associated domain to copy state from, and lacks post-parse processing
that normal drivers have, the testsuite output had several spots with
the state, coupled with a regex filter to ignore the oddity.
It is better to follow the lead of other XML defaults, by not
outputting anything during format if post-parse defaults have not been
applied, and rejecting the default value during parsing. The testsuite
needs a bit of an update, by adding another flag for when to simulate
a post-parse action of setting a snapshot state, but none of the
drivers are impacted other than rejecting XML that was previously
already suspicious in nature.
Similarly, don't expose creation time 0 (for now, only possible if a
user redefined a snapshot to claim creation at the Epoch, but also
happens once setting the creation time is deferred to a post-parse
handler).
This is also a step towards cleaning up snapshot_conf.c to separate
its existing post-parse work (namely, setting the creationTime and
default snapshot name) from the pure parsing work, so that we can get
rid of the testsuite hack of regex filtering of the XML and instead
have more accurate testing of our parser/formatter code.

The exception is the port allocate API which does some validation even

however, since the network driver may not even be installed. IOW virt

The network driver used to reload the firewall rules whenever a dbus
NameOwnerChanged message for org.fedoraproject.FirewallD1 was
received. Presumably at some point in the past this was successful at
reloading our rules after a firewalld restart. Recently though I
noticed that once firewalld was restarted, libvirt's logs would get this
message:
The name org.fedoraproject.FirewallD1 was not provided by any .service files
After this point, no networks could be started until libvirtd itself
was restarted.
The problem is that the NameOwnerChanged message is sent twice during
a firewalld restart - once when the old firewalld is stopped, and
again when the new firewalld is started. If we try to reload at the
point the old firewalld is stopped, none of the firewalld dbus calls
will succeed.
The solution is to check the new_owner field of the message - we
should reload our firewall rules only if new_owner is non-empty (it is
set to "" when firewalld is stopped, and some sort of epoch number
when it is again started).
