Similar to what was done for the channel socket in the previous commit.

Rather than depend on the RPM to put it in place, since this doesn't
cover the qemu:///session case. Currently auto allocated socket path is
completely busted with qemu:///session

https://bugzilla.redhat.com/show_bug.cgi?id=1105274

And because we chown the directory at driver startup now, this also fixes
autosocket startup failures when using user/group=root

Not sure if this is required, but it makes things consistent with the
rest of the directories.

Rather than duplicate libDir for each new path

- Make sure aarch64 host-passthrough works correctly
- Make sure libvirt doesn't choke on cpu model=host, which is what
  virt-install/virt-manager were incorrectly specifying up until recently.

virDomainGetJobStats is able to report statistics of a completed
migration, however to get usable downtime and total time statistics both
hosts have to keep synchronized time. To provide at least some
estimation of the times even when NTP daemons are not running on both
hosts we can just ignore the time needed to transfer a migration cookie
to the destination host. The result will be also inaccurate but a bit
more predictable. The total/down time will just be at least what we
report.

ListFindByID() still requires to step through items in the hash table
(in the worst case scenario through all of them), lock each one and
compare whether we've found what we're looking for. This is suboptimal
as locking a domain object means we need to wait for the current API
running over the object to finish.

Unfortunately, we can't drop the function completely because we have
this public API virDomainLookupByID which we can't drop.

This hash table will contain the same data as already existing one.
The only difference is that while the first table uses domain uuid as
key, the new table uses domain name. This will allow much faster (and
lockless) lookups by domain name.

For some devices, the $PCIDIR/vendor and $PCIDIR/device need to be
read. Iterate over them to get them as well in the the generated
apparmor profile.

Use the custom emulator pin setting with the highest priority same as
with vcpupin.

If this enviroment variable is set, the virTestCompareToFile helper
will overwrite the file content we are comparing against, if the
file doesn't exist or it doesn't match the expected input.

This is useful when adding new test cases, or making changes that
generate a lot of output churn.

Replaces a common pattern used in many test files

Commit 2a530a3e is not portable to mingw, which intentionally

The PortNumber data type is declared to derive from 'short'.
Unfortunately this is an signed type, so validates the range
[-32,768, 32,767] which excludes valid port numbers between
32767 and 65535.

We can't use 'unsignedShort', since we need -1 to be a valid
port number too.

This change is to use 'int' and set an explicit max boundary
instead of relying on the data types' built-in max.

One of the existing tests is changed to use a high port number
to validate the schema.

Commit 835cf84b dropped expectedVirtTypes argument for
virDomainDefParse*() functions, however bhyve tests still try to pass
that to virDomainDefParseFile(), therefore build fails.

Fix build by fixing virDomainDefParseFile() usage.

Fedora doesn't ship OVMF/AAVMF builds in its repos due to licensing
issues, so the recommended way to consume these bits is via Gerd's
nightly repo: https://www.kraxel.org/repos

Let's teach fedora builds about the loader/nvram pairs these packages
installed, so users don't need to edit qemu.conf to get virt-manager
UEFI support.

Some hypervisors like Xen do not have PIDs associated with domains.
Relax the requirement for PID != 0 in the locking code so it can
be used by hypervisors that do not represent domains as a process

When running on FreeBSD, there's a bug in virCommandProcessIO
polling that is triggered by the commandtest.

A test that triggers EPIPE in commandtest (named "test20") hungs
forever on FreeBSD.

Apparently, this happens because FreeBSD sets POLLHUP flag on revents
when stdin in closed. And as the current implementation only checks for
POLLOUT and POLLERR, it ends up looping forever inside
virCommandProcessIO and not trying to do one more write() that would
trigger EPIPE.

To fix that check for the POLLHUP flag along with POLLOUT and POLLERR.

When a user would specify a backing chain index that is above the start
point libvirt would report a rather unhelpful error:

invalid argument: could not find backing store 1 in chain for 'sub/link2'

This patch adds an explicit check that the index is below start point in
the backing store and reports the following error if not:

invalid argument: requested backing store index 1 is above 'sub/../qcow2' in chain for 'sub/link2'
