But only because there is some emulating layer in between.

There is no functional difference between a disk partition like 'wd0a',
a wedge like 'dk0' or a LVM volume like 'dm0'. And the partition
functionality (i.e. passing blocks for and back) is the only thing
that Xen requires. The xvbd driver adds the "disk" capabilities on
top of that.

I'd like to have vnd(4) to also support block devices as backing store,
so that it can be the "emulating layer". But since that's currently
not possible I added enough functionality to ccd(4) instead.
