So, you cannot run kvm on a paravirtualized hpv, which is why devcloud
appliance would run xen, the hypervisor running can be virtualbox
(tools/devcloud) or kvm (tools/devcloud-kvm).
It's upto the hypervisor which is running the appliance to provide
host only network, while this is ready made in virtualbox, one can
setup a virtual network for vms in kvm (Marcus should advise here).
And yes, you can do that, run mgmt server+mysql in one devcloud and
use other as host+nfs/localstorage.

use xen ?

I tried that once and it just did not work for me; maybe it's
possible, one should be able to run vms on qemu emulation. I think does that and so should be do-able.
