Commit fba6bc4 introduced the non-migratable invtsc feature, breaking save/migration with host-model and host-passthrough. On hosts with this feature present it was automatically included in the CPU definition, regardless of QEMU support. Commit de0aeaf stopped including it by default for host-model, but failed to fix host-passthrough. This commit ignores checking of CPU features with host-passthrough, since we don't pass them to QEMU (only -cpu host is passed), allowing domains using host-passthrough that were saved with the broken version of libvirtd to be restored. https://bugzilla.redhat.com/show_bug.cgi?id=1147584
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
