Yes, Stephen is correct

Well, it is hard to follow -- especially when you consider the different
Linux versions that exist/ed for Xen.

IIRC, copy was introduced with Xen 3.0, and became the default option
for 3.1 with the Linux of XenSource (2.6.18).

For the pv_ops Linux (default dom0 with Xen 4 and up), I guess that
flipping was never supported, hence copy is the only possibility with
the pv_ops kernel.

This requires confirmation by someone that follows the Linux pv_ops
kernel closer. A quick look at the git branch (jeremy's) seems to
confirm this.
