Hi, I've a two nodes hosted-engine ovirt 3.5used storage is NFS4 for the: engine, vms, iso and export I have many Linux VMs and one Windows 2008 VM. 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... URL: < http://lists.ovirt.org/pipermail/users/attachments/20150211/0c243d06/attachm...

Hi, i have a strange problem,my manager is very slow and with the gui I can not do anything on the vm and the host, but the vm are ok.

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

Hi,
I looked at the logs and the reason why host vmh-02 wasn't restarted is that PM restart failed using both other hosts (vmh-01 and vmh-03) with error:
Test Failed, [Powering off machine @ IPMI:10.9.1.11...Failed
So we couldn't restart HA VMs on another hosts, because we were not sure that host vmh-02 is really down.
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?
Thanks a lot
Martin Perina

I have a 3 host cluster setup with HA enabled and fencing enabled and
it
appears to be working properly. Executing power management stop, start, and restart work along with host shutdown/restart following a simulated crash. When network is pulled a proxy is chosen and it powers off the downed host, and then restarts it. Since the network is still down it repeats the following in events: "Host kvm01 is not responding. It will stay in Connecting state for a grace period of 162 seconds and after that an attempt to fence the host will be issued."
The real problem here is that the VM's on the host that has failed never migrate to a new host and remain down until the network is reconnected.
once the host is powered off by the proxy, HA vms will be started (not migrated) on other host, if there are resources for it.. if you have HA vms that are not started although there is another host available for it, it might be a bug, can you please attach engine.log from the time of

We have tested this with back-end storage on gluster and NFS with the same result. This is on oVirt Engine Version: 3.5.1.1-1.el6. Hosts are on CentOS 7 and the Engine is standalone on CentOS 6.6.

I've had the exact same problem during testing yesterday. The HA VMs never restarted on the other available hosts. The only difference is that we're using iSCSI storage backend.
oVirt Engine Version: 3.5.1.1-1.el6 (hosted engine) Host: CentOS 6.6
Engine logs are attached.
Thanks, Siddharth
