Assigning the Processor and the Memory

Hi ,

If I am having a quadcore machine i.e. 4 dual cores which is total of 8 processors - please let me know if my understanding is wrong.

Have an esxi host with quad core processor hosting 5 virtual machines.How are these vm's configured with respect to the processor.
I do  see an option called Virtual processors in the summary of the VM, can this settings be edited after installing the OS and may be to increse the performance of the machine.

Is the virtual processors related to the available processors on the host or can we assign as many processors we want same with memory as well.

Please let me understand the assignment of the processors and the memory to virtual machine.

You assign a vCPU to a virtual machine, you can add additional vCPUs to the VM after installing the OS. It could change the performance of the VM, if the VM can take advantage of Virtual SMP, e.g, Exchange and SQL, or other applications, but adding another vCPU, may not necessarily increase performance.

Depending upon your VMware license, you can add 4-way, and 8-way processors to the VM, but the Host OS, must be able to support multiple processors, which is dependant upon the OS License in the VM.
