Hi Mat
Thank for your reply.
The "w!" did work.
I am using an ocfs2 fs type on the shared devises so that should keep it
safe.
Cheers

As described in the two other post on this subject, you can share it,
but you have to have a file-system that is "shareable". And you need to
use "w!" instead of "w" to tell Xen that "Yes, I know I'm sharing this
file-system" [and if you actually don't care about the content of your
disk-image or the overall stability of your domain, you can of course
force multiple domains to access the same disk-image even if it's not
actually shareable - but that's like playing with matches in a petrol
station...]
