754a7f6c94 conf: Fix type of @present in _virDomainTimerDef struct
In the _virDomainTimerDef structure we have @present member which
is like virTristateBool, except it's an integer and has values
shifted by one. This is harder to read. Retype the member to
virTristateBool which we are familiar with.

8af76c3764 virDomainChrSourceDefCopy: Copy more struct members
The aim of virDomainChrSourceDefCopy() is to make a deep copy of
given virDomainChrSourceDef. However, some types were not copied
at all (VIR_DOMAIN_CHR_TYPE_SPICEVMC and
VIR_DOMAIN_CHR_TYPE_SPICEPORT) and some members weren't copied
either (@logfile, @logappend).

After this, there are still some members that are not copied
(seclabels and private data), but the sole caller
qemuProcessFindCharDevicePTYsMonitor() doesn't seem to care.
Therefore, just document this behavior so that future user is
aware.

3de95c3d51 virDomainInputDefParseXML: Move validation into validator
There is some code that validates whether parsed @bus <input/>
makes sense (e.g. some hypervisors have their own type of bus).
But this code should not live in the parser, but validator
rather. That way, we can also validate that the value we compute
(if user didn't provide any) is valid.

ddb2384f0c qemuDomainSetupDisk: Initialize 'targetPaths'
Compiler isn't able to see that 'virDevMapperGetTargets' in cases e.g.
when the devmapper isn't available may not initialize the value in the
pointer passed as the second argument.

The usage 'qemuDomainSetupDisk' lead to an accidental infinite loop as
previous calls apparently doctored the stack to a point where
'g_slist_concat' would end up in an infinite loop trying to find the end
of the list.

31e937fb3b libxl: Add lock process indicator to saved VM state
Commit fa58f571ee added a lock processes indicator to the
libxlDomainObjPrivate struct to note that a lock process was
successfully started for the VM. However, the commit neglected to
add the indicator to the VM's saved state file. As a result, the
indicator is lost on libvirtd restart, along with the knowledge of
whether a lock process was started for the VM.

This change adds support for the indicator in the domainObjPrivate
data parse and format callbacks, ensuring its value survives libvirtd
restarts.

2e2c9797c5 esx: Do not return root objects in a lookup
The lookups in esx_vi work a bit differently that we are used to.  The filters
(travelsalSpec and selectSet) choose how to look up the objects, but given a
root object the lookup lists all the objects of a requested type inside it as
well as the root object itself.  We then go through the results and find the one
which has the same name as was requested.  However in a case with nested folders
of a same name this could break when the first returned object in the list is
the parent folder as we'd select it only based on the name.  To avoid this also
add a check that the candidate we are trying to pick is not exactly the same
object (reference) as the root object.

Turns out, the commit did more harm than good. It changed

qemuDomainGetInfo() previously did not returned an error it does
now. While the calls to virProcessGetStatInfo() is guarded with
virDomainObjIsActive() it doesn't necessarily mean that QEMU's
PID is still alive. QEMU might be gone but we just haven't

 error: Failed to connect socket to '/var/run/libvirt/virtqemud-sock': Connection refused

 # virsh -c 'qemu:///system?socket=/var/run/libvirt/libvirt-sock' list
  Id   Name   State
 --------------------

Fix this by instructing systemd to delete the socket file when
deactivating the unit file for the socket.

1652babf15 qemuValidateDomainDeviceDefVideo: Reject non-default video head count for devices not supporting it
Only QXL and virtio-vga actually propagate the 'heads' attribute as
'max_outputs' to the commandline of qemu. Reject the setting when
non-default value is used for any other video type.

37c0a25ca0 qemuValidateDomainDeviceDefVideo: Refactor condition checking for qxl and virtio-vga
Subsequent patch will use the same condition so move the primary device
check into a nested condition.

4c308ea42e qemuBuildDeviceVideoCmd: Simplify formatting of 'max_outputs' property
Since there's no capability to check now, we can simply move the
formatting of 'max_outputs' earlier.

49a85978b7 qemu: capabilities: Retire QEMU_CAPS_QXL_MAX_OUTPUTS and QEMU_CAPS_VIRTIO_GPU_MAX_OUTPUTS
Both are supported by qemu-2.11 and later, so we don't have to check for
them explicitly.

Note that QXL is supported only on x86_64, thus on other arches only the
capability for 'virtio-gpu' is removed.

d35ddc6243 qemuBuildDeviceVideoCmd: Always assume support for 'max_outputs' property
Both the QXL video device and 'virtio' video device support
'max_outputs' in all qemu versions libvirt supports. This means we no
longer have to check the QEMU_CAPS_QXL_MAX_OUTPUTS and
QEMU_CAPS_VIRTIO_GPU_MAX_OUTPUTS capabilities.

6622e3cc33 virDomainDeviceInfoParseXML: Reject '0' value for ACPI index
Value of '0' is treated equivalently to when it's not provided by the
user. Reject an explicit '0' provided by the user as it would get
ignored.

In this rare case we can make the XML parser more strict, as libvirt
would never format the '<acpi/>' element if the index is '0' thus there
are no libvirt-generated XMLs we'd not load back, as of such this is
identical to rejecting it in the validation phase.
