Re: [Users] High Availability OVirt
Hi, You can use a cluster software like pacemaker or RH Cluster to make your ovirt-engine high available. I personally recommend to virtualise it on a KVM host, as keeping virtual machines high available is much easier then making all services ovirt-engine need high available (but it's possible for sure). So what happens when your engine hosts goes down: - You can't login into webadmin and user portals - high availability and live migration features of your virtual machines aren't working - You can't start/deploy new virtual machines - Your hosts and virtual machines that are already running stay up of course As clustering brings in more complexity I would use a server with RAID, redundant power supplies and redundant network interfaces (bonding) for ovirt-engine instead of clustering. Only when using desktop virtualization where availabilty of the user portal is really important I would cluster ovirt-engine. (But this is just my personal opinion) Regards, René On Fri, 2013-04-19 at 08:19 -0300, victor nunes wrote: > > Is there any way to create redundancy oVirt-engine? > We install oVirt-engine in a machine, and what happens if that burning > machine? > > > Is there anything that can be done to remedy this? > > > Att, > -- > “Encarada do ponto de vista da juventude, a vida parece um futuro > indefinidamente longo, ao passo que, na velhice, ela parece um > passado > deveras curto.

Re: [Users] oVirt 3.2.1 - VM in unknown status
Hi, I had a nfs storage problems and one of my VM's is now in unknown state. The VM is not attached to any host. The virsh tool shows that VM is not running now. Is there any way to bring that kind of VM back to life? Best regards, Piotr Hi, I found workaround for this situation. There is a possibility to change the VM status manually in database: update vm_dynamic set status=0 where vm_guid='1d5342a3-9375-49c5-bf2a-2bd444d41d09'; @oVirt developers It seems that in some situations, VM with'unknown' status has no chances to change state. When all hosts in data center are up and the VM is not attached to any host it's a dead end. In this particular situation oVirt engine administrator can't perform any actions on "lost" VM. Is any way to handle this case without database access? the state transition in this case is the engine responsibility and not the user. its done by monitoring all VMs on all Hosts periodically. Whats more interesting is how have you got to that situation and if its worth a bug please be kind to report it. Hi Roy, I reported a bug (953839). If it would be considered as worth to fix I can provide some help. I haven't introduce jet to the oVirt community. So I'm software engineer in the Polish Research and Academic Computer Network. Mainly I'm Java EE developer. We use oVirt to manage our development and testing environments. I'm very enthusiastic about oVirt project. PS sorry for my English.

[Users] Master Storage Domain in status locked.
Greetings.
Due to an unfortunate storage misconfiguration (iscsi) the Ovirt-node
was unable to mount it's master storage domain after a power outage.
During the troubleshooting I believe I have managed to get the domain in
some weird state where it now remains in status locked.
If trying to take (only) host/node online it goes back to
non-operational since it's unable to mount the master storage domain.
Rebooting the node and or the engine makes no difference.
Everything storage wise should be OK now.
Any idea on how to recover ?
vdsm.log attached
With kind regards
Jonas
