Born only a couple of weeks ago(FWN#171[3]), libguestfs
libguestfs
has progressed very far very fast.
"libguestfs
is a library for accessing and modifying guest disk images. Amongst the things this is good for: making batch configuration changes to guests, getting disk used/free statistics (see also:
), migrating between virtualization systems (see also: virt-p2v), performing partial backups, performing partial guest clones, cloning guests and changing registry/UUID/hostname info, and much else besides."

Fedora Xen List
This section contains the discussion happening on the fedora-xen list.
Dom0 Kernel Not Before 2.6.31
The upstream Xen dom0 work done by Jeremy Fitzhardinge has been cleaned up and reorganized[1] into
- xen-tip/master - Known-working branch, with only tested changes
- xen-tip/next - Current bleeding edge; should at least compile
Michael Young built[2] a new experimental dom0 kernel "version (2.6.30-0.1.2.21.rc3.xendom0.fc12) is based on the Fedora devel kernel branch and xen-tip/next branch from the pvops kernel repository." This kernel may be found in Michael's yum repo[3].
Michael added that "very few xen patches made it into 2.6.30, just bugfixes and tidy ups, so we are waiting at least until 2.6.31[4] for mainline dom0 support."
