* svirt: fix MCS label generation (CVE-2021-3631)
A flaw in the way MCS labels were generated could result in a VM's
resource not being fully protected from access by another VM were
it to be compromised. https://gitlab.com/libvirt/libvirt/-/issues/153
* Removed features
* xen: Remove support for Xen < 4.9
In accordance with our platform support policy, the oldest supported Xen
version is now bumped from 4.6 to 4.9.
* docs: Document disk serial truncation status quo
Disk ``<serial>`` is being truncated by QEMU before passed to the guest.
Since it's impossible to fix it without running into further regressions
the documentation was improved to document the intricacies.
* Bug fixes
* qemu: Fixed validation of disk ``iothread`` configuration
The validation of ``iothread`` config was previously moved to a place where
it caused bogus errors when address wasn't allocated when hotplugging a
disk. The check is now removed as it wasn't actually necessary at all.
