Hello all: This seires is an update of last version of multiqueue support to add multiqueue capability to both tap and virtio-net. Some kinds of tap backends has (macvatp in linux) or would (tap) support multiqueue. In such kind of tap backend, each file descriptor of a tap is a qeueu and ioctls were prodived to attach an exist tap file descriptor to the tun/tap device. So the patch let qemu to

Hi all, I have few simple fixes for Xen for the next release: - the first one fixes a regression in qemu-char; - the second one is just a cleanup (that is needed to simplify preprocessor dependencies); - the last one avoids setting nonblocking on Xen (as is already done for KVM). The last two patches should be backported to older branches. Stefano Stabellini (3):
