The qemuMonitorTestNew() function returns with the monitor object
locked, and expects it to still be locked when qemuMonitorTestFree
is called. The qemuhotplug test, however, explicitly unlocks the
monitor, but then forgets to lock it again. As a result the
qemuMonitorTestFree function is unlocking a mutex it doesn't own.
This bug has existed forever, but since we use normal POSIX mutexes
and don't check the return value of pthread_mutex_lock/unlock we
didn't see the error. It was harmless until the switch to the per
monitor event loop which requires the thread synchronization to
work reliably, whereupon it started crashing.

According to the linked BZ, machined expects either valid
hostname or valid FQDN (see systemd commit
v239-3092-gd65652f1f2). While in case of multiple dots, a
trailing one doesn't violate FQDN, it does violate the rule in
case of something simple, like "domain.". But it's safe to remove
it in both cases.

there was not better solution I guess.
In case we have the events the sync function is different. It allows us

But we need to do it only once. Until we get timeout on issued command

When we're using the GLib event loop though there are
things going on that we don't know about, such as use of
eventfd() file descriptors. This will break the assumptions
in the test suite, causing non-deterministic failures.
This change switches the event loop thread to run fully

The event test directly calls the internal poll event impl
APIs. It does not rely on any specific details of the poll
impl, so it is better to use the public APIs.

Use some of the existing bitmap data to add tests for
qemuBlockBitmapsHandleBlockcopy.
As the output depends on the ordering in the hash table we must also
install the "virdeterministichash" mock preload library.

Add a case where a bitmap spanning multiple images is missing one of the
intermediate components.

Add a validator which checks that a bitmap spanning multiple backing
chain members doesn't look broken. The current rules are that no
intermediate birmaps are missing (unfortunately it's hard to know
whether the topmost or bottommost bitmap is missing) and none of the
components is inconsistent.
We can obviously improve it over time.
The validator is also tested against the existing bitmap data we have
for the backup merging test as well as some of the existing broken
bitmap synthetic test cases.

Add a variable which will store the contents of the 'flags' variable as
passed in by the individual block jobs. Since the flags may influence
behaviour of the jobs it's important to preserve them to the
finalization steps.

Allow qemu access to modify backing files in case when we want to delete
a checkpoint.
This patch adds tracking of which images need to be relabelled when
calculating the transaction, the code to relabel them and rollback.
To verify that stuff works we also output the list of images to relabel
into the test case output files in qemublocktest.

Allow deleting of checkpoints when snapshots were created along. The
code tracks and modifies the checkpoint list so that backups can still
be taken with such a backing chain. This unfortunately requires to
rename few bitmaps (by copying and deleting them) in some cases.

Add a faked qemu output which would simulate scenario where libvirt
would take a snapshot and checkpoint simultaneously. This is visible in
libvirt-2-format node where bitmap 'c' appears, but bitmap 'b' which is
active in the previous layer is not present.
