kernel /xen.gz    ?
I guess this line is not correct.
2.6.28 kernel itself should already suppport pv_ops
via config file options.

module /kernel-2.6.28-rc6-tip  root=/dev/sda2 console=hvc0 earlyprintk=xen

I downloaded a working tree of the current pv_ops dom0 kernel by
following the instructions at
http://wiki.xensource.com/xenwiki/XenParavirtOps , the kernel compiled
successfully but when I try to boot it on my Dell Optiplex 755 the
system locks up after Xen prints "(XEN) Xen is relinquishing VGA

I found part of a thread on xen-devel with subject "pv_ops dom0
testing" which seems to suggest that adding "console=hvc0
earlyprintk=xen" to the kernel command line fixes a known problem, I
tried that but it did not make any difference.

Grub stanza:

title Xen 3.3 / Linux 2.6.28-rc6-tip pvops dom0
root (hd0,0)
kernel /xen.gz
module /kernel-2.6.28-rc6-tip  root=/dev/sda2 console=hvc0 earlyprintk=xen

Perhaps it is too early to be testing dom0 pvops? or I need to apply
further patches to the source tree?
