Thank you Tomas for the reply,
Yes, I want to bring it back to normal state so it would run without 
this rescue mode.
When I execute "nova rescue" and VM gets into RESCUED then 
/var/lib/nova/instances/{uuid}/console.log is filled,
but when I do "nova unrescue" and VM is in ACTIVE state this log is 
empty (I can see the process of the VM in the core machine).
I wanted to use "virtsh console instance-xxxx" as described here: 
http://www.jaredlog.com/?p=1484 to get a console to the machine but hit 
this error:
