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)? -------------- next part -------------- A non-text attachment was scrubbed...
