CPU/Threads/Cores and vCPU relationship and committing

We have a physical machine with 2 cpu's (E5649), each has 6 cores and 2 threads per core (12 threads). The kernel of that physical machine displays the 24 cpu's. On this physical machine, we're running a KVM with 12 Vcpu's and would like to know if we can go to 16 - 18 Vcpu's without any penalty or do we gain any more performance.

 

 

Thanks in advance,

It is possible to add more vCPUs (threads) to your virtual machine. The virtual machine will handle more applications at the same time and provides with better performance; however, your host computer will lost performance and Threads.
