Tried with cdrom= and with 2 devices, both don't work.

Still the same problem.

Trying file instead of tap:aio it hangs on create.

Neither do I.
Right now, performance is not a problem, I cannot get it to even boot once.

Thats what I do in my PV linux domUs, as I use routed networking instead of
Therefor I have NO bridge to connect to.

This local variable is usually later used to compose the path to qemu like
device_model = '/usr/' + arch_libdir + '/xen/bin/qemu-dm'

As on my system there is only '/usr/lib/xen/bin/qemu-dm' though it is 64bit
(ubuntu hardy) I removed that unnessessary section.

I want vnc to bind to only, as I forward vnc through ssh.

I tried adding this one, but it doesn't change anything.

Could you send me one of your complete hvm config files?
