In the past, other drivers (at least Citrix and Redhat) is somewhat of
a hassle to install. For example, you used to have to download the
whole XCP/XenServer ISO, or have RHN subscription just to get the
driver (haven't checked again, might still true).

Then there was functionality problem. Redhat's driver used to say you
can only use PV drivers for drives other than "C" (I haven't check
again in a long time whether it's still true).

Compared to that, GPLPV which is easy to download and install seems
quite superior to me. Performance has been good.

If you do decide to try them all, let us know which one you like best.
