The syntax understood by xl is documented in
docs/misc/xl-disk-configuration.txt. It is intended that it supports all
the useful syntaxes which xend did, although since the xend syntax was
never really specified it is perhaps not complete or correct.
I use 'tap:vhd:/scratch/debian-x86_32-2.vhd,xvda,w' and that works, if
you aren't using vhd I'd expect replacing the 'vhd:' with 'qcow:',
'qcow2:' or 'raw:' etc to work. (nb: xl makes no distinction between tap
and tap2 -- you always get tapdisk2). The 'aio:' is ignored by xl (it's
always on) but you can retain it for compatibility with xend if you
like.
xl-disk-configuration.txt mentions the 'tapdisk:' syntax but I don't see
it actually implemented in xl, it would probably be a nop in any case
(since tap: is sufficient to get the behaviour it specifies), in your
case it would be overridden by the 'aio:' anyway AFAICT. There is
ongoing work to improve xl's handling of the disk cfg syntax.
