This (and other replies) lead me to two possible culprits:
- either the graphical console over X11 is not a good idea (but I
can't imagine that, it shouldn't shoot the kernel)
- I always installed as a paravirtualized machine, Could it be that
the install-kernel on the 5.3-media is not aware of this and somehow
manages to shot the host (because I noticed that most recipies on the
net, including http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU
never talk about paravirtualized (so I assume they use a fully
virtualized guest)
I will try these later today (when people left the office and no one
will complain about server downtimes)
Bernhard
BTW: Just one fundamental question: as the upstream OS vendor is
switching his virtualization to KVM anyway, is it a good idea to
forget Xen and use KVM (in other words: is it stable enough for
production)?
