Thread-topic: [Xen-users] tap:aio driver for kernel2.6.32.x
Hi Fajar,

Thanks. It works when I replace tap:aio with tap2:tapdisk:aio

PS: I suggest some big gun could write some comprehensive docs to help 
migration from lower xen to xen 4.1, for example, some config files working for 
xen 3.4.2 don't work for xen 4.1.0.

Not sure. It's working in my setup. You can try:
- looking at files on /var/log/xen/*, look for the newest one and
what's on them (usually xend.log and qemu*.log will provide some
- try replacing tap:aio with tap:tapdisk:aio or tap2:tapdisk:aio
