And today, I would add the following:

Is there anyone reading this list who is successfully running Xen 3.0.x
on Debian Etch, in paravirtualization mode, without any random crashes
or data corruption?

I brought up Debian on my test box last night, and then installed Xen
from the default package (I think it was 3.0.3) -- and when I tried to
transfer a large file onto the Dom0, the copy of the file on the Dom0
was corrupted -- and then shortly afterwards, the Dom0 encountered file
system problems and switched the file system into read-only mode.  When
I repeated this experiment running straight Debian (not Xen), everything
worked perfectly.

As far as I'm aware, my hardware is OK -- no disk errors logged, and an
extended memory test (memtest86+) has not revealed any problems.  It
really looks to me like there's something wrong with Xen.  Any ideas?

Are you using any network block device storage such as AoE or iSCSI?

Did you accidentally mount the file system read write in more than one place at a time?

Did uncleaning (i.e. xm destroy) shutdown the guest?

I have noticed that read-only mounting thing just the other day when a guest was imporperly shutdown (xm destroy or similar).

Todd
