[Xen-users] kernel oops with GFS in domU

[Kyler Laird <Kyler@xxxxxxxxxxxxxxx>]

This is using Xen 3.0 testing (8259).  SMP was disabled in the
domU kernel to allow GFS to compile.

I'm not sure this is a Xen issue but I thought there were some
people running GFS under Xen so it might be worth posting.

update...I tried OCFS2 and FUSE (also in unstable/8438) with the
same result.  I've heard that others have been able to run GFS2
in domU so maybe it just requires the right versions and configs?
I'd be happy to pay for help.
