This time i will try to be more specific on my problem. I am always trying to install and run a VM with xcp on my machine with ubuntu 11.10. First step for doing this is the creation of a sr. And I can do that with this command: xe sr-create content-type=user type=nfs name-label=condivisa shared=true device-config:server=n11 device-config:serverpath=/var/condivisa After that a pbd is automatically created, but it is not attached to my this sr. I update my pool list also, setting as default, the sr I just dreated with: Xe pool-param-set uuid=<uuid of the pool> default-SR=<uuid of my SR> I try then a pbd-plug command and I get this error.

I took the error from the /var/log/SMlog folder. I created sr of iso and nfs type, but nothing changed (but I think the nfs type is the right one thou). Any tips?
