--- Comment #15 from Roger Pau Monné <royger at freebsd.org> ---
The fact that you get "ada" or "xbd" devices depend on what you put in the
guest configuration file. If the disk is attached as a "xvd" it will show up as
"xbd" in FreeBSD, and if it's attached as "hd" it will show up as "ada". As
long as you see something like:

xbd0: 51200MB <Virtual Block Device> at device/vbd/832 on xenbusb_front0
xbd0: attaching as adaX

In dmesg it means it's using the PV disks.

I will try to look into this, but it's not going to be now (I hope I will be
able to get to it by the end of the month).
