can you try to use losetup to setup a loop device for each of the
tap:aio files you have and then specify phy:/dev/loopN in the config
file rather than tap:aio?
For example I mean:
losetup /dev/loop0 /workspace/agent/appliances/XenFileServer-3.20/rootfs
then in the config file:
phy:/dev/loop0,xvda1,r
