Patch for xen-unstable.hg

2010/5/31 Boris Derzhavets <bderzhavets@xxxxxxxxx>
I've attempted to process patch for xen-4.0.0-0.7.f12.src.rpm it gives an errors.
Is it written for xen 4.0 ? I did some manual check .

this patch remove problems with blktap2 devices:
1. If we use blktap2 disk device then DomU does not boot. Returned error:ÂFile 'vhd:/path/.../disk.img' doesn't exist.
2. Created blktap2 disk device does not accessibleÂimmediately after connecting: If we use pygrub then DomU does not boot. Returned error: Disk is not accessible.
