this bug status was moved to MODIFIED before engine vt5 was built,
hence moving to on_qa, if this was mistake and the fix isn't in,
please contact rhev-integ
Comment 3 Artyom 2014-10-07 11:23:27 UTC 
Verified on vt5, I see that patch just prevent to create or update vm in preferred mode in vmNumaNodes != 1 and if it not pinned, I really don't understand why I can't use this mode for more that 1 node. But it's problems of libvirtd, so I verify bug.
Comment 4 Artyom 2014-10-07 12:23:40 UTC 
Was success to change vm mode to preferred with next scenario:
1) Specify vm host to start to host with numa support and deny migration("Do not allow migration"), change NumaNodeCount to 1 and mode to preferred and also pin this VNUMA to PNUMA, click ok.
2) Edit this vm and just change "Start running on:" to "Any Host in Cluster", click ok.

Now you have vm without NUMA pinning in preferred mode.
Comment 5 Artyom 2014-10-07 13:24:38 UTC 
Also when vm with preferred mode, engine success to run vm(if no VNUMA appear, engine also not run vm with tune mode). So I will open another bug that I success to change mode to prefer.
