Unpredictable data that's sent over a secure channel is still
unpredictable. Or are you saying it's difficult to set up a secure
channel without good entropy?

I'm not massively familiar with the systems that do this, but a cloud
provider is going to have a secure backplane for poking VMs, so I
imagine they'd reuse that.
