[Qemu-devel] [PATCH 0/3] virtio support for QEMU

[Anthony Liguori]

This patch series adds support for paravirtual device drivers that use 
virtio.  virtio is a frame work in Linux for abstracting the details of 
virtual IO so that a single device driver (like networking) can be used 
with multiple hypervisors using a small shim layer.  Currently, Linux 
supports a virtio network and a virtio block device and a shim layer for 
lguest.   I have a PCI shim layer for virtio that is suitable for use in 
QEMU.  This is currently in Rusty Russell's virtio tree awaiting the 
Linux merge window to open again.

Regards,

Anthony Liguori

Hi Anthony, Rusty,

Can you set up an uptodate git repository for the kernel part, other 
community members
will also benefit.
I got an oops for vring_kick immediately on the first pkt while testing 
this patchset.
Going to debug it tomorrow, hopefully it's not because of patching.
Thanks,
Dor.

Yeah, patches are required that aren't yet in Rusty's queue.  I'll 
update the list once we've gotten his queue straightened out.  The oops 
is most certainly from the use of unsigned int in vring_init instead of 
unsigned long.  I have a patch on 
virtualization@lists.linux-foundation.org for that but I don't think 
Rusty's pulled it in yet.

Anthony Liguori

I'm actually on vacation this week and next week, so my queue won't be updated 
for a while.  I'll put them all in once I'm back on deck...

I can host it in a branch on kvm.git, if I knew what patches to 
include.  Anthony, can you post pointers?

Can you post this to kvm-devel as well next time?  I'm sure there is 
considerable interest in this work among kvm developers.

That's the required patches from rusty's queue plus my patches based off 
the kvm git tree as of 83f9425dc148dbe0d373b7e07f221affff9e91cb
