[Users] Need to recreate public RSA key on node

[Bob Doolittle]

Hi,

I inadvertently overwrote my root authorized_keys file on my host/node 
(copied instead of appended :( ), so I need to find the proper public 
RSA key to put back there for ovirt-engine.

But I can't seem to find the private (or public) key on the Engine. 
There is no actual account "ovirt-engine" on the Engine. Where does this 
key come from?

Any other suggestions on an easy way to recreate the file? This is my 
only node, and it hosts my Primary Data Domain, so I don't think I can 
easily remove/re-add it.

My node was up at the time, and surprisingly it remains up and 
operational at least for now. What is the remote root ovirt-engine login 
used for?
