Re: [Xen-users] migrate virtual machine to another server

[Joseph Glanville <joseph.glanville@xxxxxxxxxxxxxx>]

Hi,

Ensure this path is correct:
 'phy:/dev/europe_storage/bill-wdisk,hda,w',
Also if you aren't using the QEMU ioemu driver make sure you have
PVonHVM drivers installed or GPLPV if this is a Windows guest.
Is there any error output when you try to start the domain?

Joseph.
