[Fedora-xen] Xen disks are read-only after some time.

[Jan ONDREJ (SAL)]

Hello,

  I have problems to run Fedora 10 guests on Fedora 8 dom0. My servers are
running some time, but then they was unable to write changes to disks. There
is nothing special in logs or dmesg. This happens aprox 24-48 hours after
restart. When trying to log anything to disk, after reboot this is gone. I
can log it over network, but don't know what to log. Can somebody help me to
debug this problem?

My problem was reported on RH and kernel bugzillas:
	https://bugzilla.redhat.com/show_bug.cgi?id=478414
	http://bugzilla.kernel.org/show_bug.cgi?id=12331
but without any answer. :(

  May be there is something similar like in this thread:
http://lkml.indiana.edu/hypermail/linux/kernel/0901.0/00121.html,
just on my server there is only ext3, not ext4. Also trying to turn off
daily backups (which uses snapshots) without success.

  After reboot to fc8 kernel everything is running fine again, but running
fc8 kernel on fc10 is not a good solution (except that F8 is EOL).

  Thank you.
