Hi all,

Searched but can't find anything.
I am wondering what are the new features that will come with blktap2,
compared to blktap ?

Thanks.

Right now it's mainly an architectural thing.

- The original blktap duplicated a lot of what originally 
  constituted just blkback.

- Access to virtual disk images from within dom0 gets 
  more straightforward. Which matters a lot for some things dom0 can 
  do to disks.

- Request dispatch between kernel and userspace will get way more
  efficient at some point.

- Blktap on non-Xen systems ...

- ...

Also: blktap2 has a driver for the vhd format.
