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.

No back up, just the hard drive. The data is fine its the server board that is fried. I
will eventually get a replacement server that I can use. So this brings me back to my

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:

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]).
[1] update vdc_options set option_value = false where option_name = 'InstallVds'

Maor

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!

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.

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. 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
