Yes; I wished you could boot IOS(X*) or Junos on bare metal, 
given they all support x86_64 hardware, but the vendors have 
opted to keep tight control of things by fitting the OS 
inside a VM.

So the leanest and most manageable deployment you can have 
with this is:

        - Metal
        - Hypervisor
        - Router OS

CSR1000v is supported on ESXi only today, and to load it up, 
you require vSphere client. I'd rather you didn't, but it's 
thin enough and manageable, so as long as you keep it 
simple, you should be stable.

Junos will run on Qemu or KVM natively, so no external 
management required, although there are some you can use.

Mark.
