Hi Maurice, In the mail I sent, I proposed to add those Hosts to a new engine. Those VMs should be registered as external VMs in your engine, and then you can manage them and start, stop or reboot them. before doing that, please also set InstallVds parameter in the Data Base at vdc_options table to false, to prevent the Host to be re-deployed when it is being registered to the new engine (see [1]). p.s. After stabilizing your environment, you might be interested to upgrade to 3.5. In oVirt 3.5, there is a new DR feature which should help recovering the engine from those scenarios which you just encountered (see [2]).

In the original mail I explained it could help interacting with those VMs though I raised my doubts about it, Using external VMs will still provide the engine th ability to interact with those running VMs, though you will only be able to see and stop them. I guess, if you don't want to use the engine, a better alternative is to use the vdsClient as Douglas proposed.
before doing that, please also set InstallVds parameter in the Data Base at vdc_options table to false, to prevent the Host to be re-deployed when it is being registered to the new engine (see [1]).

I am running 3.4.2 in that environment. I was wondering if there is a way to start, stop, reboot the VMs that are present on the hosts that are still running? I did not see any emails from Maor. Thanks

Hi Maurice,
What's the oVirt environment that you were running? 3.3, 3.4, 3.5? When you say interact, is it about to start the VM that are you asking? Could you please clarify? Have you tried the Maor's suggestion?
For now, I would say to start with: http://wiki.ovirt.org/VdsClient
Thanks Douglas

Yes the db and engine are offline
do you have a backup of the db to restore the engine?

Just to make sure, this means that when it comes to file system , etc.. you also have your storage resources available, right?
You lost the engine with the db, am I correct ?
I'm CCing someone that might have the exact answer for that.

I just recently had the hardware that acts as the engine crash. I have a blinking amber light on the server. I have servers on the remaining hosts. How do I, or can I use vdsm to interact with the VMs that are still present on those hosts without the engine?

Hi Maurice,
In the mail I sent, I proposed to add those Hosts to a new engine. Those VMs should be registered as external VMs in your engine, and then you can manage them and start, stop or reboot them.
I do *not* think this is correct. the new engine will only show the VMs. it will not know of the storage domains or the disks, etc. I think this will *not* work! In the original mail I explained it could help interacting with those VMs though I raised my doubts about it, Using external VMs will still provide the engine th ability to interact with those running VMs, though you will only be able to see and stop them. I guess, if you don't want to use the engine, a better alternative is to use the vdsClient as Douglas proposed.
before doing that, please also set InstallVds parameter in the Data Base at vdc_options table to false, to prevent the Host to be re-deployed when it is being registered to the new engine (see [1]).
p.s. After stabilizing your environment, you might be interested to upgrade to 3.5. In oVirt 3.5, there is a new DR feature which should help recovering the engine from those scenarios which you just encountered (see [2]).
[1] update vdc_options set option_value = false where option_name = 'InstallVds' [2] http://www.ovirt.org/Features/ImportStorageDomain#Disaster_Recovery_flows

That vdsclient reference is exactly what I was looking for. I will have to use that until I can figure out what Im going to do about getting the hard drive with the engine data into a new server.
