When I submitted the qcow2 patch for blktap, suggestions came up that the qemu block drivers should be used also for blktap to eliminate the current code duplication in ioemu and blktap. The attached patch adds support for a tap:ioemu pseudo driver. Devices using this driver won''t use tapdisk (containing the code duplication) any more, but will connect to the qemu-dm of the domain.

Hi tinc list members, There were some problems with Ivo's email adresses (both zarq@iname.com and zarq@spark.icicle.dhs.org) so I resent the stuff to the mailling list. ============================================= Hi Ivo, Hier is een oplossing voor een bugje in flush_queue(), en ook wat andere troepjes zoals een tincd scheduler. Dit werkt wat beter, omdat de

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
