Hi,<br>
I've a two nodes hosted-engine ovirt 3.5used storage is NFS4 for the: engine, vms, iso and export<br>
I have many Linux VMs and one Windows 2008 VM.<br>
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.<br>
<br>
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<br>
<br>
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.<br>
any advice?<br>
PS: is there a good solution to gather and analyze all the logs from ovirt's hypervisors and engine, storage...etc?<br>
<br>
thanks in advance.<br>

Hi, i have a strange problem,my manager is very slow and with the gui I can<br>
not do anything on the vm and the host, but the vm are ok.<br>
I tried to look at the log, but I have not seen anything that would explain<br>
the problem.<br>

What are you using to access the manager UI on the client (OS and browser)?<br>

Hi,<br>
<br>
I looked at the logs and the reason why host vmh-02 wasn't<br>
restarted is that PM restart failed using both other hosts<br>
(vmh-01 and vmh-03) with error:<br>
<br>
Test Failed, [Powering off machine @ IPMI:10.9.1.11...Failed<br>
<br>
So we couldn't restart HA VMs on another hosts, because we were<br>
not sure that host vmh-02 is really down.<br>
<br>
I also noticed that even getting PM status of host vmh-02 is<br>
problematic, fence agent returned this message:<br>
<br>
Power Management test failed for Host vmh-02.Done<br>
<br>
but it also returned successful operation. This looks very very<br>
suspicious!<br>
<br>
Could you please execute following command from vmh-01 or vmh-03<br>
to test PM agent on vmh-02<br>
<br>
fence_ipmilan -a <IP> -l <USER> -p <PASSWORD> -o status -v -P<br>
<br>
where <IP>, <USER> and <PASSWORD> contains values valid for vmh-02?<br>
<br>
<br>
Could you please send us also vdsm.log from machines vmh-01 and<br>
vmh-03 so we could investigate details of fence agents execution<br>
failures?<br>
<br>
Thanks a lot<br>
<br>
Martin Perina<br>
