Running various functions on a couple small VM clusters makes a lot of sense.
I agree, it makes some sense, especially if you are control plane bound. But, nearly all my routers run between 1% and 10% cpu. Ymmv. I have feeling that running a bgp rr on cheap / standard / commidity vm is pretty exotic from a support perspective. 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. Your network is probably different

You don't need LDP on RR as long as clients support "not on lsp" flag (different implementation have different names for it) There are more and more reasons to run RR on a non router HW, there are many reasons to still run commercial code base, mostly feature set and resilience.

there are patches for both code-bases and some preliminary support for vpnv4 in quagga, but other than that neither currently supports either ldp or the vpnv4/vpnv6 address families in the main-line code.
