We should be raising an error if accel3d is present for any
non-virtio video as well, incase someone tries it for say 'qxl'

  One can not issue monitor commands manually during async calls thru
designated API while this could be useful for testing/debugging purposes.
qemuDomainQemuMonitorCommand uses job of type QEMU_JOB_MODIFY and any async
call disable parallel execution of this type of job. The only state that is
changed is taint variable. AFAIU the only place we can mess is resetting
taint flag in qemuProcessStop routine under some async job. But this can not
happen thanx to both virDomainObjIsActive check in qemuDomainQemuMonitorCommand
and resetting active status in qemuProcessStop before taint flag.

  Change job type to QEMU_JOB_QUERY and thus make the API call available for
most of async jobs.

This way :make syntax-check in ViM will point you at the offending line.

Invoke the script only once instead of once for every file.

Guest agent interaction is considered privileged.

Also remove the duplicate build-aux entry from .gitignore.

Pass 'true' if we are not dealing with a migration.

The test has too many USB devices.

This code was attempting to handle some implicit <console> XML
formatting for manually assembled DomainDef, since previously the
console<->serial compat copying was only done at XML parse time.

Nowadays it's done via virDomainDefPostParse ->
virDomainDefAddConsoleCompat, which all manual DomainDef builders
already call, so we can drop this workaround.

When domXML contains only <console type='pty'> and no corresponding
<serial>, the console is "stolen" [1] and used as the first <serial>
device. When this "stolen" console is accessed from the libxl driver
(in libxlConsoleCallback and libxlDomainOpenConsole), check if the
targetType is VIR_DOMAIN_CHR_CONSOLE_TARGET_TYPE_SERIAL, and use the
"stolen" device in def->serials[0] instead. Prior to this change,
creating a domain with input XML containing only a <console> device
and subsequently attempting to access its console with
'virsh console' would fail

error: internal error: character device <null> is not using a PTY

[1] See comments associated with virDomainDefAddConsoleCompat() in
    $LIBVIRT-SRC/src/conf/domain_conf.c:

We are done if the string ends and move to another nesting
level if we find a dot.

Make rewriting it easier.

We support up to four levels of nested USB devices in the guest.

Add a test for a domain using all four and a negative test for a domain
using five.

Allow modification of specific vCPU states via the guest agent.

Allow gathering available vcpu ids, their state and offlinability via
the qemu guest agent. The maximum id was chosen arbitrarily and ought
to be enough for everybody.

Documentation for the "guest-set-vcpus" command describes a proper
algorithm how to set vcpus. This patch makes the following changes:

- state of cpus that has not changed is not updated
- if the command was partially successful the command is re-tried with
  the rest of the arguments to get a proper error message
- code is more robust against malicious guest agent
- fix testsuite to the new semantics

Add a straightforward implementation for using the new APIs.

To allow finer-grained control of vcpu state using guest agent this API
can be used to individually set the state of the vCPU.

This will allow to better control NUMA enabled guests and/or test
various vCPU configurations.

Add a rather universal API implemented via typed params that will allow
to query the guest agent for the state and possibly other aspects of
guest vcpus.

Since it's rather tedious to write the dispatchers for functions that
return an array of typed parameters (which are rather common) let's add
some rpcgen code to generate them.

Make them work again...  The xml2xml had been working, but the xml2argv
