Two of my Xen servers will not start up

I was configuring a couple of xen servers for cPanel use. I got to the point of testing a couple of accounts being created on the servers. The accounts were created fine but then the servers crashed. Now when I try to start the servers from my cloudmin control server I get an error.

Starting up seattle.cloud.alurium.com .. .. failed : PTY PID: 5245 Using config file "/xen/seattle.cfg". Error: VM name 'seattle' already in use by domain 1
