Re: [Xen-devel] [PATCH 0 of 5] PV on HVM Xen

Hard to say. Just black screen with no output and reboot.
Usually when Xen comes up and Dom0 crashes , there is some screen printout,
in my case nothing on the screen. Serial console is required again :(

Can you tell whether its Xen itself crashing, or if the dom0 kernel is crashing?

Once Xen is patched, it should be sufficient to run a patched domU hvm kernel (you don't need to update your dom0 kernel).
