If you care about passing cache leaves, you probably can be expected to pass a number of threads that matches the host, making the vCPUs a multiple of the number of threads, and pinning the virtual cores to the physical cores. But in general, I'd say that the cache _is_ shared with another thread. It may be that the thread is not part of the VM---that depends on things such as the pinning of vCPUs to physical CPUs. Paolo
