It
is not obvious to me that it should be the case.
Why is feature_grant_copy (without feature-persistent) better than
feature-persistent (without feature_grant_copy)? Shouldn't we simply
avoid grant copies to copy data to persistent grants?

Hi Kevin,
I agree with you, and if you would be so kind to send the patches, even
untested, they would be much appreciated. Anthony or I will make sure to
test them appropriately and fix them, if they turn out to be incomplete
or partially broken. Would that be OK?

The Xen toolstack uses "vhd" to specify a disk in VHD format, however
the name of the driver in QEMU is "vpc". Replace "vhd" with "vpc", so
that QEMU can find the right driver to use for it.
