IIRC Xen patches were first sent for 2.6.15 kernel. Those were rejected and not integrated into vanilla kernel. I can't remember the reason for that. Next attempt failed when others wanted to have the paravirt ops (pv_ops) framework instead, which enables Linux kernel PV support for any hypervisor, not just for Xen. Then it took a while to get the generic pv_ops framework done and merged into Linux kernel. And after that it has taken a lot of time to port the Xen domU from the original "Xenlinux" to pv_ops framework. pv_ops Xen domU support has been in mainline Linux kernel since 2.6.23. And now there is active development going on to get the pv_ops dom0 working and merged into Linux. Btw Redhat started this work earlier, and it is now being continued by Xensource (Jeremy Fitzhardinge). http://wiki.xensource.com/xenwiki/XenParavirtOps -- Pasi -- Fedora-xen mailing list Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
