I think your userbase prefers the way Red Hat goes. If you do a reality
check on the current Python implementation and its memory usage, it is so
far from an ESX equivalent that I put my money on any Qemu userspace
version.

So if you say this new domain will not take at least 128MB extra memory,
that could be interesting.
