Here's a patchset with vhost support for upstream qemu,

addressed.
Please consider for merging.

Comment on kvm usage: rather than require users to do if (kvm_enabled())
and/or ifdefs, this patch adds an API that, internally, is defined to
stub function on non-kvm build, and checks kvm_enabled for non-kvm
run.

This adds vhost binary option to tap, to enable vhost net accelerator.
Default is off for now, we'll be able to make default on long term

vhostfd implies vhost=on.

This connects virtio-net to vhost net backend.
The code is structured in a way analogous to what we have with vnet
header capability in tap.
We start/stop backend on driver start/stop as
well as on save and vm start (for migration).

Hi,
I usually mail out negative test reults but this time I've just
pulled and merged to my 4 different CRIS, PPC and MicroBlaze trees
from upstream and things Just Worked.
Good work to everybody involved!

The inverted conditions as argument to the function looks wrong
at a glance inside translate_one. Since we have an easy function
to produce the inversion now, use it.

This is a per-cpu flag; there's no need for a spinlock of any kind.
We were also failing to manipulate the flag with $31 as a target reg
and failing to clear the flag on execution of a return-from-interrupt
instruction.

Use an ExitStatus enumeration instead of magic numbers as the return
value from translate_one. Emit goto_tb opcodes when ending a TB via
a direct branch.

Hi,
I have a question regarding virtio_blk_load().
(qemu-kvm.git d1fa468c1cc03ea362d8fe3ed9269bab4d197510)
VirtIOBlockReq structure is linked list of requests, but it doesn't seem to be
properly linked in virtio_blk_load().

In this case, we're losing
Hi All,
I've found a problem in qemu-dm from xen 3.3.1_18546_12-3.1 from
SLES11. I've posted this question to xen-devel as well, but I thought
that I'd post it here since the problem appears to be in qemu-dm.
I began investigating this problem when we found that if we pass two
instances of our b
