Subject: [one-users] CPU / vCPU Question

Hi there,

can anybody tell me why it would be desireable to provide e.g. 12 real CPUs and just one vCPU? This is something ONE lets me do.

What would be use cases for the other way around (1 real CPU, 12 vCPUs)?

I also did some benchmarking with sysbench under Linux and found that the only option making sense to me is having CPU == vCPU. But maybe I am missing something?

Cheers,
Christian
