I'm just building an updated Fedora 20 image which I'll upload later
today.
The F20 image has been uploaded. You should notice when you install
it that it will download the full disk image again, and also that
a file "fedora-20.x86_64.2" will be created in ~/.cache/virt-builder/
(.2 == revision 2)
I tried various experiments, and it seems as if the Xen modules are
included in the initramfs even if you upgrade the kernel when running
virt-builder itself. So all looks good over here, but I didn't
actually try booting the disk image on Xen itself.
While I have your attention ...
It'd be great if libguestfs could use Xen as a backend (in addition to
current qemu, KVM and UML backends). Most likely that would involve
one of two approaches:
(1) Modify the libvirt backend (src/launch-libvirt.c) so it works
properly when the hypervisor is Xen. If you buy into libvirt, this
one is probably going to be less code.
(2) Add a new backend (src/launch-xl.c ?) which uses native Xen APIs
to create the appliance.
