[Pkg-xen-devel] debian xen packages : work with 2.6.16, reboots when loading dom0 with 2.6.17

[Jérôme Petazzoni]

I was giving a try to Debian Xen packages (it looks very promising by
the way ; I just happen to love the « new » grub which handles xen
images, for instance!) ; I have a box which boots correctly with
xen-hypervisor-3.0-i386_3.0.2+hg9697-2 and a 2.6.16 dom0 kernel, but
crashes when trying to boot linux-image-2.6.17-2-xen-686_2.6.17-7

The result is the same on two boxen (my Pentium M laptop and a Pentium D
production server) ; I cannot capture the serial output of my laptop
(the serial port seems hosed when booting...) but I could get the output
from the Pentium D (attached file).

Googling a bit made me think it was *maybe* a version mismatch between
the hypervisor and the dom0 ; but it sounds dubious, since the
hypervisor seems very recent, and works with an older kernel.

Does this issue ring a bell ?

As a side question -- I saw a PAE hypervisor package ; are there PAE
dom0 images too ? (the debianbase repository, which used to hold some
PAE packages, seems quite outdated now -- no update since march/may)


best regards
