Indeed. Pygrub does not have support for the btrfs filesystem and when
the PV guest boots after install it will fail. We use grub.xen from
the grub2-x86_64-xen package to boot para-virtualized VMs installed with
the btrfs filesystem. For XenServer to support btrfs a bug will need to
be entered against Citrix.

The original problem in this bug was a missing kernel/initrd pair on the
openSUSE 13.2 NET ISO media. I don't think the media is ever remastered
once it releases so no fix is available. In any case, openSUSE 13.2 goes
out of support mid January.
