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

["Kasai Takanori" <kasai.takanori@xxxxxxxxxxxxxx>]

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,
