Fedora Virtualization List

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

Virt Status Report

Justin Forbes posted^[1] a Fedora virtualization status report. Justin pointed out F13 bugs^[2] now include Important and Pony classifications in addition to Blocker and Target.

RHEL and Fedora Virtualization Feature Parity

Robert Day wondered how the virtualization features^[1] of Red Hat Enterprise Linux 5.4 compared to Fedora 12.

Daniel Berrange explained^[2] "The KVM based virtualization in RHEL-5.4 is not nearly so far behind Fedora as you might think. The libvirt mgmt stack in RHEL-5.4 was rebased to be near parity with Fedora 11, and KVM in RHEL-5.4 is also pretty close to that using what's best described as a hybrid of kvm-83 and kvm-84."

-For stability and long-term maintainability, I wonder if you've

-the hypervisor, but if you use libvirt / virsh / virt-manager, the
-future upgrade path to KVM is reasonable.  All tools stay the same,

-(including /dev/sr0), could this effect other valid usage of these
