kvm-85 comes in two flavors: the traditional kernel+qemu package

Hi Avi,
Here are a few fairly trivial build patches - they fix
building kvm.git using --with-patched-kernel alongside an unconfigured
kvm.git tree.
Cheers,

We need to know this so that we can avoid doing things that
are specific to building kvm.ko - e.g. when we are only
doing header-sync.

We still run header-sync in this case, which requires configure

Hi,
KVM has support for PCI device assignment using VT-d and AMD IOMMU, but
there are a number of inter-related issues that need some further
discussion:
- Unbinding devices from any existing device driver before assignment
- Resetting devices before and after assignment
- Helping users

Hi Weidong,
In general, this looks like a good cleanup.
With deassign_device() fixed to only require assigned_dev_id, I would be
happy to ACK this whole patch.
However, it would be much, much easier to review the patch if you had
split it into multiple patches e.g.
1) Make
Hi Alex,
Just had a quick looked over these and they seem pretty good, but some
broad comments:
- The logic around is this a NIC+TAP pair? would be good to have a
better API around. We need this to merge virtio GSO support too.
Anthony had some ideas here.

Primarily because the current tun driver in Linux has a bug that it can
drop unicast packets requested to be included in the filter if it
overflows the exact match table.
