Avi, thanks. The patch fixes the issue for the XO image and there are no
more MSR read errors.
I'm still not sure why when starting the image with kvm enabled the
drawing of the GRUB screen is so painfully slow, but without kvm it is
fast.
Any ideas?

I found that I had to move to a newer kernel (2.6.23.1 is what I used) to get
SMP guests to boot on RHEL5 hosts. It appears to be an issue with the host
kernel.

The following patch fixes 1a483ef4040ed380bf69d684783d06a617073256 so that the
parent PIC pointer is used to send the edge irq0 instead of the PIC pair and
that is an incompatible pointer type as reported in :

wrong patch, this was meant to go to the slave PIC, so it will use s-pics[1]
instead of s-pics[0].
also from my tests it might seem that tdf is irrelevant anyway with the new
clock work and haven't been able to find a case where enabling it (so
triggering this buggy code path) migh be needed.

This patch consolidates the irqflags include files containing common

This patch consolidates part of the tlb handling functions for the x86

Among other things, using -traditional as a gcc option stops us from
using macro token pasting, which is a feature we heavily rely on.
There was still a use of -traditional in arch/x86/kernel/Makefile_64,
which this patch removes.
I don't see any problems building kernels in my x86_64 box
The interrupt initialization routine becomes native_init_IRQ and will
be overriden later in case paravirt is on. The interrupt array is made visible
for guests such lguest, that will need to have their own initialization
mechanism (though using most of the same irq lines) later on.

This patch turns the set_p{te,md,ud,gd} functions into their

Also, it adds pte_update() and pte_update_defer() calls whenever

i386 as close as possible.

This patch prepares the x86_64 architecture initialization for
paravirt. It requires a memory initialization step, which is done
by implementing 64-bit version for machine_specific_memory_setup,
and putting an ARCH_SETUP hook, for guest-dependent initialization.
This last step is done akin to i386
This patch turns the page operations (set and make a page table)
into native_ versions. The operations itself will be later
overriden by paravirt.
It uses unsigned long long for consistency with 32-bit. So we
have to fix fault_64.c to get rid of warnings.
