Hello,
on my xen host, Debian 5.0 I have few domU's running, most of them are Lenny's,
a couple is running at Etch (Debian 4.0). All domU's are running stable except
of one (Etch / Debian 4.0). This one crashes almost daily and I wasn't able
figure out the reason why.
Inside the domU there is nothing installed except of base system and Zimbra ZCS
5.0 and its dependencies.
