#14024 worksforme 3.4.2. "Processor" tab : relation between host and guest cpu is not clear mirak
Description

https://www.virtualbox.org/manual/ch03.html#settings-processor

On the "Processor" tab, you can set how many virtual CPU cores the guest operating systems should see. Starting with version 3.0, VirtualBox supports symmetrical multiprocessing (SMP) and can present up to 32 virtual CPU cores to each virtual machine.

You should not, however, configure virtual machines to use more CPU cores than you have available physically (real cores, no hyperthreads).

The documentation is not explicit about the type of relation there is between host and guest cpu. From explanations I had, there is no relation, and there is no one for one mapping between host cpu and virtual cpu. The VM just picks the specified number of cpu from the host in the settings. From the evasive explanation I receveid, I can't tel what is the allocation strategy at runtime.
