I think I have cleared the issue regarding the reverse mapping.
I missed the fact, that the write permission is associated with the PTE.
I thought that it was associated only with the kernel structures
maintaining the physical page-frame.
But I want to confirm whether a shadowed guest page re

Well, that line should better not be removed. I get a hang otherwise,

This patch adds a make file dependency for compiling exec.c with archs that
still have dyngen dependencies.
This allows powerpc qemu to now compile without the --disable-cpu-emulation
flag.
Signed-off-by: Jerone Young <[EMAIL PROT
These patches remove all traces of --disable-cpu-emulation configuration flag.

Hi all,
I was reading the "The shadowy depths of the KVM MMU" presentation by
Avi Kivity.
From my understanding of shadow page-table,
Guest Page Table : maps GV -> GP
Shadow Page Table : maps GV -> HP
What is meant by shadowed guest page ? (Does it refer to : the guest PT
pages that h

Description: Binary data
This patch allows to boot from network using the virtio-net adapter
provided by KVM.
It applies on etherboot-5.4 sources from
git://git.etherboot.org/scm/etherboot.git
[why etherboot-5.4 ?
because it doesn't hang like gPXE and ROM size is only 32 KB]

If we're not gonna do anything (case in which failure is already
reported), we do not need to even bother with calculating the linear rip.
This is a nitpick, but I saw it while doing some testing, so here's
the patch.

hi
in the wiki i read that migration fro amd to intel and back should work.
i tried it several times an i get an error (kernel 2.6.25 / kvm-69):

Thanks for comments
Basically we are on the same page, while I didn't find your patch about
irq assignment, can you post it in this thread again, thx?
Below patch makes all PCI devices use level-trigger , active low
