[Libvir] Question about specifications of virsh start

[Masayuki Sunou <fj1826dm aa jp fujitsu com>]

Hi

I have a question about specifications of virsh start.

It is necessary to remove "type=ioemu" from the configuration file of Xen,
when HVM domain installed Para Virtualized Driver use unmodified driver
on Xen 3.0.3.

But,libvirt always adds "type=ioemu" to vif of HVM domain in xm_internal.c.
Therefore virsh start cannot start correctly HVM domain installed
Para Virtualized Driver.

Could you teach why does libvirt disregard setting of configuration
file and set type=ioemu ?

Thanks,
Masayuki Sunou.
