Description Robin Norwood 2006-04-20 15:33:09 UTC
Xen provides a UUID for running domains, but this UUID is only available from
dom0, not domU.  Management applications (such as RHN) need a way to associate
the domain attached to a given dom0 with the running instance.

The method for paravirtualized hosts as discussed will probably be to expose the
UUID via /proc.  Fully virtualized hosts will need to use a different method, so
another bug will be filed for them.

Comment 1 Robin Norwood 2006-04-20 15:36:51 UTC
See bug #189498 for fully virtualized domains.

Comment 2 Mark McLoughlin 2006-08-01 13:53:29 UTC
Looks like /sys/hypervisor/uuid exists in kernel-xen-2.6.17-1.2488.fc6
