A few commits ago, in aeecbc87b7, I've implemented command line
generation for ACPI HMAT. For this, we need to know if at least
one guest NUMA node has vCPUs. This is tracked in
@masterInitiator variable, which is initialized to -1, then we
iterate through guest NUMA nodes and break the loop if we find a
node with a vCPU. After the loop, if masterInitiator is still
negative then no NUMA node has a vCPU and we error out. But this
exact check was missing comparison for negativeness.

To cite ACPI specification:
Heterogeneous Memory Attribute Table describes the memory
attributes, such as memory side cache attributes and bandwidth
and latency details, related to the System Physical Address
(SPA) Memory Ranges. The software is expected to use this
information as hint for optimization.
According to our upstream discussion [1] this is exposed under

QEMU allows creating NUMA nodes that have memory only.
These are somehow important for HMAT.
With check done in qemuValidateDomainDef() for QEMU 2.7 or newer
(checked via QEMU_CAPS_NUMA), we can be sure that the vCPUs are
fully assigned to NUMA nodes in domain XML.

Commit 82576d8f35 used a string "on" to enable the 'pmem' property.
This is okay for the command line visitor, but the property is declared
as boolean in qemu and thus it will not work when using QMP.
Modify the type to boolean. This changes the command line, but
fortunately the command line visitor in qemu parses both 'yes' and 'on'
as true for the property.

Firstly, SEV is present only on AMD, so we can safely assume x86.
Secondly, the problem with looking up capabilities in the cache by arch
is that it's using virHashSearch with a callback to find the right
capabilities and get the binary name from it as well, but since the
cache is empty, it will return NULL and we won't get the corresponding
binary name out of the lookup either. Then, during the cache validation
we try to create a new cache entry for the emulator, but since we don't
have the binary name, nothing gets created.
Therefore, virQEMUCapsCacheLookupDefault is used to fix this issue,
because it doesn't rely on the capabilities cache to construct the
emulator binary name.

The semantics of the backup operation don't strictly require that all
disks being backed up are part of the same incremental part (when a disk
was checkpointed/backed up separately or in a different VM), or even
they may not have a previous checkpoint at all (e.g. when the disk
was freshly hotplugged to the vm).
In such cases we can still create a common checkpoint for all of them
and backup differences according to configuration.
This patch adds a per-disk configuration of the checkpoint to do the
incremental backup from via the 'incremental' attribute and allows
perform full backups via the 'backupmode' attribute.
Note that no changes to the qemu driver are necessary to take advantage
of this as we already obey the per-disk 'incremental' field.
