[RFC PATCH 0/2] Google extension to improve qemu-nvme performance
Hi Rob & Mihai,
I wrote vhost-nvme patches on top of Christoph's NVMe target.
vhost-nvme still uses mmio. So the guest OS can run unmodified NVMe
driver. But the tests I have done didn't show competitive performance
compared to virtio-blk/virtio-scsi. The bottleneck is in mmio. Your nvme
vendor extension patches reduces greatly the number of MMIO writes.
So I'd like to push it

[PATCH 00/15] RFC xen device model support
Hi all,
this is the long awaited patch series to add xen device model support in
qemu; the main author is Anthony Perard.
Developing this series we tried to come up with the cleanest possible
solution from the qemu point of view, limiting the amount of changes to
common code as much as possible. The end result still requires a couple
of hooks in piix_pci but overall the impact should be very
