It's not possible *yet*, at least for Fedora. I've seen some people on this 
list say they were running 2.6.24 as a pv domu, from some other distro. 
Either that distro is still forward porting the standard xen patches, or they 
got pvops to work for them (and them alone). Fedora seems more inclined to a 
slow but correct approach - that is acceptable to the mainline kernel folks, 
so that their code will eventually be merged.
