Host has 2GB of swap, so I doubt that's the case here. However I managed
to crash xend again and it seems to be somehow related to heavy disk I/O
from domU.

On this latest crash I had only two domU's running and dom0 had plenty
of memory to use. However I was running mkfs.ext3 on fairly large image
which seemed to trigger the crash. First I lost an ssh connection to
dom0 and regained it after a while, but xend was gone by then.

I'll try to debug the situation more, but if anyone has any ideas I'll
be glad to hear about them. After all my goal is (suprisingly) an stable
system. One thing I did was that I increased dom0-min-memory even more,
and it's now at 512MB. Let's see if that's enough as Adam suggests or is
the problem somewhere else.
