In that case, I'd guess that Gleb just forgot to call virDomainSetMemoryStatsPeriod, perhaps? I've just performed the same test with CentOS 7 at the host and CentOS 7 at the guest. Everything works.
# virsh dommemstat vm1 actual 1048576 swap_in 0 swap_out 0 major_fault 751 minor_fault 3958627 unused 375900 available 1017988 rss 978248 I don't know the reason it doesn't work with ELRepo 3.10.45 kernel but I'd really like to. According to https://bugzilla.redhat.com/show_bug.cgi?id=601690 memoryStats should work at host's side starting from 2.6.32-52.el6 so I suppose the problem is the guest kernel. Do you think this could be caused by an old version of virtio_balloon driver?
