When starting a domain on a host which lacks a vmx-* CPU feature which is expected to be enabled by the CPU model specified in the domain XML, libvirt properly marks such feature as disabled in the active domain XML. But migrating the domain to a similar host which lacks the same vmx-* feature will fail with libvirt reporting the feature as missing. This is because of a bug in the hack ensuring backward compatibility libvirt running on the destination thinks the missing feature is expected to be enabled. https://issues.redhat.com/browse/RHEL-40899 Fixes: v10.1.0-85-g5fbfa5ab8a Signed-off-by: Jiri Denemark <jdenemar@xxxxxxxxxx> --- src/cpu/cpu_x86.c | 44 +++++++++++++++++++++++++++----------------- 1 file changed, 27 insertions(+), 17 deletions(-)
