Fedora Xen List

This section contains the discussion happening on the fedora-xen list.

No Xen dom0 in Fedora 12 Hopefully 13

Zhang Enming was disappointed[1] to learn[2] the pv_ops dom0 support[3] for hosting Xen guests, dropped in Fedora 9, is still not present in Fedora 12. Zhang referenced numerous videos documenting success in creating "a fully working Xen pv-ops dom0 Fedora 11 host operating system."

While there are experimental patches which may be applied[4] [5] to the kernel to enable support for dom0, they are not yet in the upstream kernel which forms the basis the Fedora kernel package.

It was decided[6] two years ago this month that Fedora "simply cannot spend more time forward porting Xen kernels" and "the plan is to re-focus 100% of all Xen kernel efforts onto paravirt_ops." See FWN#137.[7]

Pasi Kärkkäinen noted[8] "pv_ops dom0 kernel has only recently started working for many/most people, so it was too late for F12 release" and "There are still some missing features, most notably missing blktap2 support for tap:aio: file-based images."
