Xen users - Feb 2009 - Running Xen over NFSv3

Does anyone, is anyone running Xen on NFSv3 successfully?
What are some of your pain points/success points?

Have you tried a clustered file system with better results such as DRBD or GFS?

TIV,
Matt

DRBD isn''t a cluster file system.  it''s a network-replicated
block device

xen@nfs: yes
All my dom-u resides on a nfs-exported area

Point of attention:
1) Fast enough network, specially for live mifration.
2) When using multiple DOM-0''s, be carefull not to start the same dom-u
of multiple nodes''s
3) it is advised that the dom-0 "should not be the NFS-server"

Not tried drbd/gfs/ocfs (yet).
Clients with I-scsi should also work....
