needs one more fix - http://gerrit.ovirt.org/#/c/31439/
Comment 6 meital avital 2014-08-28 03:00:25 EDT
Verified - av11

Note: regarding step 3 - the calculation of 'Total Virtual CPUs' should be sockets*cores <= 160 (not including threads).

Roy Golan - if you have any comment or more steps that you want us to verify please specify.
Comment 7 Roy Golan 2014-08-31 02:31:03 EDT
can you just specify what's the vm setup (cpus, cores) and the output of the vdsm log when running the VM?

if you can do this grep right after the vm stars

egrep 'vcpu|topology' /var/log/vdsm/vdsm.log

please see comment #7 - the final verify would be to get the numbers
out as well and to see they are expected
