RHEL7 VM in RHEV as KVM hypervisor (nested KVM)

Hello.

I need to do some kind of inter data center "switchability" to make some critical application highly available. Important factor is to have the ability to online migrate its host os. I invented only one possible way to achieve this: have a two RHEV VMs working in two RHEV data centers. Both VMs would act as KVM hypervisors (in terms of nested kvm) for another VM which would be switched between these two VMs.

As I can see RHEL7 supports netsted parameter in kvm_intel module.

Now the question is will Red Hat support such solution ?
