Xen pv_ops domU support has been in mainline (kernel.org) Linux kernel since 2.6.24,
so Xen PV domU support is automatically in every new kernel release.

Afaik Ubuntu does support running as Xen PV domU (they enable Xen pvops domU support)
in their normal kernels nowadays, just like Fedora does.

Xen pv_ops dom0 support is being developed and finalized atm, and it'll be upstreamed soon.

More information about various Xen Dom0 capable kernels:
http://wiki.xensource.com/xenwiki/XenDom0Kernels

And information about Xen pvops dom0 development:
http://wiki.xensource.com/xenwiki/XenParavirtOps

pv_ops dom0 is available today, and it'll be the standard/default dom0 kernel
in the upcoming Xen 4.0.0 release (4.0.0-rc6 is the latest release candidate).

Hopefully that helps.
