Hi All,
I sent the patch to make blktap work with PV-on-HVM.
For system volume to boot hda or xvda,
I corrected the patch.

This patch made it possible to use either.
disk = [ 'tap:aio:/xen/test/rhel5ga_full.img,hda,w' ]
or
disk = [ 'tap:aio:/xen/test/rhel5ga_full.img,xvda,w' ]
It is assumed that hda is a volume of the system
if both xvda and hda are specified.
disk = [ 'file:/xen/test/rhel5ga_full.img,hda,w',
'tap:aio:/xen/test/drive2.img,xvda,w' ]
Best Regards,

Subject: [Xen-devel] [PATCH] Allow blktap to be able to be booted as
systemvolume for PV-on-HVM
Hi All,
We were testing the PV driver on the HVM domain.
When blktap was booting system volume, PV-on-HVM domain was not able to be
started.
The configuration file is specified as follows.
disk = [ 'tap:aio:/xen/test/rhel5ga_full.img,hda,w' ]
The error occurred by the initialization of system volume in qemu-dm.
qemu: could not open hard disk image 'aio:/xen/test/rhel5ga_full.img'
It is because "aio:" is added to the head of params in xenstore.
However, qemu-dm open device by params.
This patch corrected the problem of params on the qemu-dm.
