patches for an idea posted in April. Daniel added a public API for converting
back and forth between the native hypervisor configurations and {{package|libvirt}} XML representations<ref>http://libvirt.org/formatdomain.html</ref>.
 
Daniel's changes enable
Xen guest conversion "to/from both XM config format ({{filename|/etc/xen}} files), and the SEXPR format used by XenD".
"For QEMU, it implemnets export of domain XML into the
QEMU argv format" and conversion from QEMU argv into domain XML.
 
"With this available, it
makes it very easy for people using QEMU to switch over to using <code>libvirt
for</code> management."

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 Package-x-generic-16.pnglibvirt 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."
