Re: [Xen-devel] [PATCH] Allow blktap to be able to be booted assystemvolume for PV-on-HVM(TAKE 2)

["Takekazu Okamoto" <tokamoto@xxxxxxxxxx>]

Kasai-san,

Why did you make a patch only for boot disk?
I have a patch for all disks on SLES10SP1 (3.0.4). (Not yet in
SLES10SP1 tree)
Windows can boot up in HVM domain with our PV drivers for blktap
disks.
For your reference, it is attached in this mail.
I know this is for 3.0.4, not applicable for latest.

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.
However, the patch has not been applied yet.
Could you apply this patch? Or, please give the comment to me.

Best Regards,
