Description Robin Norwood 2006-04-20 15:36:13 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.

For fully virtualized hosts, we will not be able to expose this data in /proc,
so it will need to be exposed via DMI.

See bug #189497 for UUID exposure in paravirtualized domains.

Comment 1 Daniel Berrange 2006-09-29 21:14:32 UTC
I've tested that xen > 3.0.2-31 RPMs provide SMBIOS data to fullyvirtualized
guests. Please run 'dmidecode' in a HVM guest & confirm that the UUID data
satisfies your requirements. 

Comment 2 Daniel Berrange 2007-01-11 21:35:52 UTC
This is long since fixed in both Fedora & RHEL.
