Hi All,

I sent the patch to make blktap work with PV-on-HVM.
I corrected the part that had been pointed out in the Xen community.

・All xvdN disk is looked like hdN.
・All tap disks are checked.(tap:aio, tap:sync, tap:vmdk, etc.)

We cannot use blktap for the volume of the system with PV-on-HVM
and are embarrassed.
Could you apply this patch? Or, please give the comment to me.

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' ]

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.
