I've attached a copy of the xl console output, but basically the server hang at "Mount-cache hash table entries: 512". Again the VM is paravirtualised, and again I get a qemu-dm process for it. The references to this message are normally related to memory issues, but the server has only 1000M of ram, so can't see it causing too much of a problem. Is this related to the other problems I'm seeing or completely separate? thanks, Anthony
