We lacked testing for xen, i tried do do some testing, but it's not easy.
when creating the grub entry, try to copy the kernel parameters into the
module section for vmlinuz.
and furthermore, you'll have to have a second module section for the initrd.
We would love if you'd be able to help us out on xen testing, can you join QA
team for this? so that for pre-releases, you can test out Xen support? or
perhaps you can join packaging team, and try to do something about creating a
default grub entry. alas, i don't think such a thing is easy, and don't know
in what way to do this.
also, is 512MB enough for dom0, if dom0 is used as backend storage? i thought
dom0 required some memory for file caching?
also, with systemd, we'll have to convert the init scripts, but luckily, we
won't be needing xend (since the new xl implementation doesn't require it)
thanks in advance.
