We are planning to do the same thing but with a different approach,
which will be some what efficient.
[Note: I am assuming we are using lxc for O.S. level virtualization,
even though we can use any other platform].

Consider one scenario:

Simple case:
       Here for xen their are 3 V.M.s running
       1) Dom 0
       2) Dom 1 (lxc)
       3) Dom 2 (windows)

Modified case:
       Here we will modify the lxc implementation to make it aware
that its running over xen in virtualize mode and will also make some
changes in hypervisor and Dom0 to make it aware that we are also
having one or more VMs running over Dom1.
       So hypervisor and Dom0 will be aware that total 5 V.M.s are running.

Few Advantages:
       1. This implementation will make the distribution of resources
simple, because xen is aware of how much actual VMs are running.
       2. Process migration of VMs(running over lxc) will be possible
here in the case like, we want to migrate VM to other hardware where
lxc might not be available.

[Note: It will also have all the advantages of O.S. level virtualization].
