Re: [ovirt-users] Engine Hardware Crash

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' [2] http://www.ovirt.org/Features/ImportStorageDomain#Disaster_Recovery_flows Regards, Maor ----- Original Message ----- > From: "Maurice James" <mjames(a)media-node.com&gt; > To: dougsland(a)redhat.com > Cc: "users" <users(a)ovirt.org&gt; > Sent: Friday, September 12, 2014 10:18:01 PM > Subject: Re: [ovirt-users] Engine Hardware Crash > > I am running 3.4.2 in that environment.
