Commit 88957116c9d3cb4705380c3702c9d4315fb500bb switched to use
memory-backend-* for regular VM memory as well. That change indirectly
started using 'host-nodes' for system memory which results in QEMU
calling mbind() to bind the system memory to specific NUMA node if the
VM XML contains the configuration similar to this:
...
<numatune>
<memory mode='strict' nodeset='0'/>
</numatune>
...
Once the VM was started with that configuration it was no longer
possible to change the memory NUMA nodeset.

Extend the TPM backend XML with a node 'active_pcr_banks' that allows a

choices for PCR banks are sha1, sha256, sha384 and sha512. When the XML
node is provided, the set of active PCR banks is 'enforced' by running
swtpm_setup before every start of the VM. The activation requires that
swtpm_setup v0.7 or later is installed and may not have any effect
otherwise.

It may happen that qemuProcessStop() is called from "qemu-event"
thread. But this thread doesn't have any virIdentity set
(virIdentity being thread local) and therefore it may be unable
to open connection to secondary drivers. It is unable to do so
in split daemon scenario, because in there opening a connection
is coupled with copying current thread identity onto the
connection. Code-wise, virIdentityGetCurrent() returns NULL which
in turn makes virGetConnectGeneric() fail. This problem does not
occur in monolithic daemon scenario, because no identity copying
is done there.
Long story short, inability to open secondary driver connection
can lead to unwanted results. Therefore, do what
qemuProcessReconnectHelper() does - set the new thread identity
to be the one of the caller.

due to QEMU developers discovering a flaw with the design of the QEMU
commandline switch used to implement the libvirt switch that will
likely result in a new and different method of selecting hotplug
modes. Because the libvirt switch has not been in any official
releases of libvirt, we are still able to remove it completely, rather
than deprecating it.
