Ymmv. I have feeling that running a bgp rr on cheap / standard / commidity vm is pretty exotic from a support perspective.
Not really. Since July last year. The worst I've had was the HP server shutting down in a London data centre due to environmental overheating. Beyond that, similar requirements as with a router, if you avoid the VM clustering goodness they all preach.
So running a bgp rr on a vm may make sense in theory, but my network control planes are not too busy and vm bgp is a unique/ exotic support model.
Amongst very many other things, running an RR on my core router means I need to touch my core router code if I want that exotic routing feature. I'd rather not, if my core router (in-path) is really just forwarding traffic between PoP's. But agree, our networks are probably quite different :-). Mark.
