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@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com> |

Libvirt API for virtualization
Libvirt provides a portable, long term stable C API for managing the virtualization technologies provided by many operating systems. It includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER Hypervisor.
For some of these hypervisors, it provides a stateful management daemon which runs on the virtualization host allowing access to the API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other languages including Python, Perl, PHP, Go, Java, OCaml, as well as mappings into object systems such as GObject, CIM and SNMP.
