Description Ilanit Stein 2012-07-19 13:48:46 UTC 
Description of problem:

Run once of VM with setting: Total cores=4, cpu socket=2,
Fail on can do action: No available (UP) host in the cluster,
Though the real problem is that the host cpu fits: Total cores=2, cpu socket=1.
  
Version-Release number of selected component (if applicable):
SI10 setup, rhel6.3 hosts

How reproducible:
always


Expected results:

Give error like: Cannot run VM, host CPU and VM cpu settings mismatch.

Error in engine.log:

2012-07-19 15:56:18,426 WARN  [org.ovirt.engine.core.bll.RunVmOnceCommand] (ajp-/0.0.0.0:8009-5) [5072c1aa] CanDoAction of action RunVmOnce failed. Reasons:VAR__ACTION__RUN,VAR__TYPE__VM,ACTION_TYPE_FAILED_NO_VDS_AVAILABLE_IN_CLUSTER
Comment 3 Oded Ramraz 2012-07-19 20:33:55 UTC 
The problem here is that the host has not enough CPU cores to run the VM and instead it prints wrong error regarding no available UP hosts in the cluster.
Ilanit , please attach the relevant engine logs as well.

caused by http://gerrit.ovirt.org/#/c/5848

either I'll revert this optimisation fix or mesh it to fit all size

Comment 7 Oded Ramraz 2012-08-29 06:47:54 UTC 
Error while executing action: Cannot run VM. There are no available running Hosts with enough cores in VM's Cluster .

Not a perfect grammar , but much better
