Here's a patchset with vhost support for upstream qemu,
rebased to latest bits, and with all comments I'm aware of
addressed.
Please consider for merging. Anthony, if you are still deliberating
some issues, maybe the series can be merged partially? This will at
least reduce the amount of noise
Will be used by vhost to attach/detach to backend.

event notifiers are slightly generalized eventfd descriptors. Current
implementation depends on eventfd because vhost is the only user, and
vhost depends on eventfd anyway, but a stub is provided for non-eventfd
case.
We'll be able to further generalize this when another user comes along
and we
vhost needs physical addresses for ring and other queue fields,
so add APIs for these. In particular, add binding API to set
host/guest notifiers. Will be used by vhost.

vhost net backend needs to be notified when

Support host/guest notifiers in virtio-pci.
The last one only with kvm, that's okay
because vhost relies on kvm anyway.
Note on kvm usage: kvm ioeventfd API
is implemented on non-kvm systems as well,
this is the reason we don't need if (kvm_enabled())
around it.

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
when we know it's stable.
vhostfd option can be used by management, to pass in the fd. Assigning
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).

will be worked on/submitted separately.

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.
While rest of qemu code still uses if (kvm_enabled()), I think this
approach is
The semantics of -no-shutdown are awful.
I'd personally prefer to see the option deprecated and a new set of
options introduced with clearer semantics.
Currently, -no-shutdown does too many things. It affects reboot
behaviour, shutdown behaviour, the behavior of the SDL close button.

Older Linux guests don't activate the bus master enable bit. So for those we
can just try to be clever and track if they set the DEVICE_OK bit even though
bus mastering is still disabled.
Under that condition we can disable the windows safety check. With that logic
in place both guests should
