Yes, it was a failure to not actively work on pv_ops based dom0 already
earlier.
At the moment Xensource is working on that, and the plan atm is to get
pv_ops based dom0 patches ready for Linux 2.6.29.
http://wiki.xensource.com/xenwiki/XenParavirtOps
Latest pv_ops dom0 patches: http://xenbits.xen.org/paravirt_ops/patches.hg/
These patches have already been sent to lkml for review and comments..
Then again it will take a while to catch up with all the feature currently
present in the Xenlinux 2.6.18 tree..
