It Finally happened. I have this bad habit of updating all of my virtual Ubuntu servers at once which in turn puts a lot of load on the hosts. Tonight was the first time that I lost the main solid state cache drive on the host which in turn took the main servers that host this site along with my others. Luckily I have shared storage (which is backed up) on my NAS4Free box. The big dilemma was manually migrating the config files on the other host to activate the Virtual Servers. With a bit of googling I ran across a very helpful command which I tweaked a bit for my younger version of Proxmox. The commands below will bring your virtual machines back to life.

First you will need to be absolutely sure that the dead node is indeed dead. Otherwise you are going to complicate life in a terrible way.
Second, you will want to set the expected votes in quorum to 1 to make the live host realize that its the only one that matters anymore.

Next you will issue a series of commands being mindful that you will need edit to coincide with your host names and the VM ID's of the virtual machines you which to manually migrate.
For Example

mv etc/pve/nodes/yourdeadhostname/qemu-server/deadvmID.conf /etc/pve/nodes/yourlivehostname/qemu-server/

If you are watching your live node at this point, you will see your virtual machines automagically appear on the live host.
You can now fire your VM's up while you prepare to rebuild your failed host.
