Re: [Xen-users] RE: RedHat DomU hanging

[Mike Brady <mike.brady@xxxxxxxxxxxxxx>]

My understanding is that when you define storage in the way that you
have, the DomU is expecting to see a "real" disk, complete with a
partition table.  From the commands that you have indicated that you
have run, you didn't partition the disk.

In the DomU use fdisk (or what ever your preferred partitioning tool is)
and add a partition.  Set its type to LVM (8e from memory).  Then do a
pvcreate on the partition which will probably be /dev/xvda1 if you do
the whole disk as a single partion.

There is way for DomU to use a partition directly (meaning no partition
table), but I do not recall how to do that.
