Either that or to bolt the pv disk backend onto the front of blktap's
userspace process is the path which we (Xen upstream) would like to
take. Both avoid the kernel side component of blktap. However at the
moment the qdisk which xen uses is rather slow, this will be "fixed"
when Xen transitions to the upstream version of qemu as device model
and/or when someone finds the cycles to do the blktap-in-userspace
However AIUI XCP has a dependency on blktap today and cannot wait for
these future developments.
