Thanks for your responses.
VM was up but network was down in it so I could not use ssh.
I didn't know the trick with with VNC password. Thanks Simone it may come handy in the future.
I recreated the self hosted engine and imported the Data storage domain.
Now I have another problem. The VMs are visible in the "VM Import" tab but there is nothing in "Template import" tab.
When I imported the first VM with "Allow partial" option selected it just disappeared after the import and I cannot find it.
How can I use it now?
Thanks
Jarek
