Fedora 9 Xen pv_ops

What’s this pv_ops business all about? Well, as Dan explained, for a long time we’ve been forward-porting Xensource’s (now 2.6.18 based) kernel tree in an effort to try and have our Xen kernel not lag behind Fedora’s bare-metal kernel. Now that the upstream kernel has gained the ability to run on Xen using pv_ops (but only as i386 DomU, currently) we’ve taken the decision to stop wasting our time forward porting Xensource’s tree and put all our focus into improving the feature set of pv_ops based Xen.

pv_ops itself is a set of hooks in the kernel so that support for running on different hypervisors can be cleanly added to the kernel, with the added bonus that the kernel can detect at runtime which hypervisor it is running on and adapt itself accordingly. This means that, in the long run, Xen support should be more akin to a device driver than a huge fork of the kernel.
