Thanks for the reply. Sorry I didn't provide more details, but, yes,
these are HVM domains. I use PV domains whenever possible, but in the
case of Windows XP, that isn't possible, so I have to use HVM. I
haven't tried suspending to OCFS2 with a PV domain, but I may give that
a shot. Still, I think it's strange that it works perfectly fine to my
ext3 and reiser filesystems, but fails on OCFS2.

that
won't detach correctly. The bigger issue, though, is that if I try to
do an
"xm save" on a domain and put the file onto the OCFS2 volume, the save
fails
after a couple of seconds and a few bytes of data. If I save the file
to
the local filesystem (ext3 or rieser) it works fine, but a save to the
OCFS2
volume doesn't seem to work. Also, once the xm save fails, the domain
gets
into a weird state that an "xm restore" or "xm resume" or
"xm unpause"
doesn't seem to help. Then I have to reboot the physical server
because the
qemu-dm process goes into a "defunct" state and won't close out
and
release
the file. Unfortunately I didn't get log files the last time this
happened,
but I'll try to capture that the next time I see the behavior. In the
meantime, if anyone else has any ideas, I'd appreciate the input.
If you have a *qemu-dm*-process, you are propably using HVM domains. I
think
this is a bad idea, because:
- SLES10 has support for PV-domains in it*s kernel (AFAIK)
- PV is generally faster than HVM
- Suspend works reliable for PV-domains
- Depending on your very exact xen version, HVM don*t work reliable
with
suspending.
So, try a PV-setup, if possible.

Steffen
