Re: [Xen-devel] Need help..

[Rolf Neugebauer <rolf.neugebauer@xxxxxxxxx>]

does dom0 still have /dev/hda8 mounted?
unmount it.
how does dom0 have /dev/hda6 mounted?
if it is mounted read/write, mount it read-only.

for all partitions:
If you want to mount a partition rw in one domain it *can not* be
mounted in any other domain
If you want to mount a partition in multiple domains it has to mounted
*read-only* in *all* domains.
