[PATCH 00/22] qemu: Fix migration from libvirt older than 9.10.0 when vmx is enabled
This series fixes a migration regression introduced in 9.10.0 release
which added support for a bunch of vmx-* CPU features. Domains with vmx
feature enabled started by libvirt 9.9.0 or older cannot be migrated to
current releases 9.10.0 and newer.
After this series migration works again with libvirt 9.9.0 and older in
both directions. Migration from the affected releases to the fixed
version works as well, but the other direction remains broken unless the
fix is backported.
See patches 1/22 and 4/22 for more details about the issue and the fix.
