Commit 1268820a removed obsolete index() function and replaced it by
strchr.  Few versions of gcc has a bug and reports a warning about
strchr:

constant will always evaluate as true [-Wlogical-op]

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.

Every domain that grabs a domain object to work over should

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
avoids declaring the obsolete index().  See also:

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'

Resolves: https://bugzilla.redhat.com/show_bug.cgi?id=1177062

Some storage protocols allow to have the @path field in struct
virStorageSource set to NULL. Add NULLSTR() wrappers to handle this
possibility until I finish the storage source error formatter.

virCommandNewArgList can use virCommandNewVAList.

The hostdev check can error out right away.

Build fails on non-Linux systems with this error:

  CC       util/libvirt_util_la-virnetdev.lo
util/virnetdev.c:364:1: error: unused function 'virNetDevReplaceMacAddress' [-Werror,-Wunused-function]

util/virnetdev.c:406:1: error: unused function 'virNetDevRestoreMacAddress' [-Werror,-Wunused-function]
virNetDevRestoreMacAddress(const char *linkdev,
^
2 errors generated.

The virNetDev{Restore,Replace}MacAddress() functions are only used
by VF-related routines that are available on Linux only. So move these
functions under the same #ifdef.

Because packets going through the egress from a bridge (where our
bandwidth limiting takes place) have no information about which
interface they came from, the QoS rules that we create instead
use the source MAC address of the packets to make their decisions
about which QDisc the packet should be in.

One flaw in this is that when a guest changed the MAC address it
used, packets from the guest would no longer be put into the
correct QDisc, but would instead be put in an "unprivileged"
class, resulting in the bandwidth "floor" (minimum guaranteed)
being no longer honored.

Now that libvirt has infrastructure to capture and respond to
RX_FILTER_CHANGE events from qemu (sent whenever a guest
interface modifies its MAC address, among other things), we can
notice when a guest MAC address changes, and update the QoS rules
accordingly, so that bandwidth floor is honored even after a
guest MAC address change.

In one of my previous patches (b68a56bc) I made class_id to
format more frequently. Well, now it's formatting way too
frequent - even for regular active XML. Users don't need to see
it, so lets format it only for the status XML where it's really

qemuDomainSetMemoryFlags() would allow to set the initial memory greater
than the <maxMemory> field. While the configuration would not work as
memory hotplug requires NUMA to be enabled and the
qemuDomainSetMemoryFlags() API does not work on NUMA guests this just
fixes a corner case.

The fix is still worth though as it allows to induce an invalid
configuration and make the VM vanish on libvirt restart.

Additionally this tweaks error message to be more accurate.
