[libvirt] [PATCH 0/5] Fix migration from older libvirt with hugepages

Since libvirt is able to use memory-backend-{ram,file}, we were using it unconditionally, then we realized it might break migration from older libvirt, so we fixed the memory-backend-ram, but forgot about memory-backend-file. This series fixes the file backend as well and uses the memory-backend-file only when it is needed. Fortunately, there is no verison of libvirt that would know about such configuration and, at the same time, not use these new objects, so there is no old libvirt from which the migration would be broken from (due to this particular reason).
