Comment 1 Artyom 2014-12-28 11:28:28 UTC 
This patch http://gerrit.ovirt.org/#/c/35782/ broke one of automation tests
Also it's not good idea to cancel cpu pinning validation, because now if you enter incorrect pinning information and run vm, vm will failed and you will receive libvirt error in vdsm log, that not desire behavior at all.
Comment 2 Michal Skrivanek 2015-01-06 14:43:11 UTC 
simple fix is MODIFIED in 3.5.z (ovirt-3.5 branch)
Comment 9 Scott Herold 2015-01-19 15:36:51 UTC 
Due to the fundamental differences in the various architectures, we need to error on allowing an admin to use a good configuration.  For this purpose, I am favoring passing through invalid configurations to libvirt vs. blocking potentially good configurations from running at all.
