Good afternoon
We have just relocated an OVS infrastructure, OVM Manager starts up but I cannot access it via the Web Console, I get this error message

If I try to access the OVM command line I get this error message:
ssh -l admin localhost -p 10000
ssh: connect to host localhost port 10000: Connection refused
I can ssh to localhost normally.
If I run an xm list command on the physical hosts I can only see two guests whereas there should be 12 to 15.
Does anyone have a solution.
