[Libguestfs] Xen drivers for virt-builder images

[George Dunlap]

I've just been playing around with virt-builder, and it seems like a
pretty useful tool.  However, it seems that in a number of the images,
the initrd file is missing drivers for Xen virtual block and network
devices.  This results in a VM that can't find its root device.

The files needed are drivers/block/xen-blkfront.ko and
drivers/net/xen-netfront.ko.  They seem to be present in centos-6 and
ubuntu-14.04, but not in rhel-7rc or fedora-20.

Whom would I contact to get these added?

Thanks!
