--- Comment #1 from Roger Pau Monné <royger at freebsd.org> ---
AFAIK when using QEMU with Xen the emulated chipset is a PIIX which doesn't
support SATA, and hence the option won't be available. This is not a limitation
of libvirt or FreeBSD, but rather of Xen itself.

Note that however using IDE or SATA is not going to make much difference
performance wise, it's all emulated by QEMU and hence slow. Your best option is
to use the Xen PV drivers (usually called blkfront) in the guest in order to
obtain the best performance, anything emulated is going to be slower.
