The windows 2008 VMs is acting as a second AD, it's the second time in a month where the VM hangs and the cpu usage is 100%.I have this problem only with this VM only. I tried to look into vdsm logs, but no luck so far, all I found isGuestMonitor-Win2k8x64-AD2::DEBUG::2015-02-11 12:01:02,158::vm::486::vm.Vm::(_getUserCpuTuneInfo) vmId=`ce0bcb92-90e8-45a7-9b9f-cfed10e920d6`::Domain Metadata is not set Is there a log file where I can follow the behaviour of the VM, because for now I have no clue about what is causing this problem. any advice? PS: is there a good solution to gather and analyze all the logs from ovirt's hypervisors and engine, storage...etc? thanks in advance. -------------- next part -------------- An HTML attachment was scrubbed...

I also noticed that even getting PM status of host vmh-02 is problematic, fence agent returned this message: Power Management test failed for Host vmh-02.Done but it also returned successful operation. This looks very very suspicious! Could you please execute following command from vmh-01 or vmh-03 to test PM agent on vmh-02 fence_ipmilan -a <IP> -l <USER> -p <PASSWORD> -o status -v -P where <IP>, <USER> and <PASSWORD> contains values valid for vmh-02? Could you please send us also vdsm.log from machines vmh-01 and vmh-03 so we could investigate details of fence agents execution failures?
