Fedora has been shipping paravirt-capable kernels for a while now, and I don't think there are extra patches to support that. The non-upstreamed, patches still needed piece is the Xen hypervisor itself. That's the part that Fedora has _not_ shipped for a while, due to the workload of trying to maintain patches against current kernels. The nice thing about Xen (vs. KVM) is that when a paravirt OS is available (e.g. almost any Open Source OS), you don't need any special hardware to get a near-full-speed virtual host. With KVM, you must have a CPU with virtualization extensions supported and enabled. AMD leaves hardware-virt out of a few of the low-end CPUs, and Intel a few more. -- Chris Adams <cmadams@xxxxxxxxxx> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
