They use domUloader, which mounts the filesystem and copies out the
kernels. I worry that a maliciously crafted fs image would compromise

I most confess to not atually having read the patches...  What I
imagined was a way of invoking a binary (or script) to read a file from
a filesystem. The binary might be linked against e.g. libext2fs, or have
an fs parsing implementation compiled in.
