Awesome, thanks.

I meant this page:
https://help.ubuntu.com/community/Xen
The sed runes it has you type in to change the grub boot order aren't
correct anymore, for example; and if we default to xl it should ideally
be updated to reflect that.

Is it not possible for libvirt to use Xen / KVM / HyperV / whatever if
they are present, and not use them if they are not present?
If not, it doesn't seem to be very well designed...
Anyway, I'll give it a spin sometime this week. Thanks!
