    How many cpu/core should I choose?


    I installed RHEL 6.3 under windows 7 using visual machine, my computer has 4 cores/8 threads, how many cpu, core should I give to RHEL? Does here cpu means core in windows 7?

    The cpus are virtual cpus.
    You could even assign more to a VM than you physically have cores, although this is generally not recommended.

    As for how many to actually assign:
    This depends on the kind of workload in the VM.
    If you plan to use cpu heavy tools, then assign more than one.

    If I put 2 cpus, 1 core. Will it actually on 2 cpus under windows 7 task manager?

    Afaik, the relation is more complex.
    But if you assign e.g. two virtual cpus to a VM and programs within that VM saturate them both, then I would expect to see also two real cores busy in w7 task manager.

    But actually:
    Try it. You can add and remove CPUs from a linux VM without problem while it is down.
    And even adding/removing CPUs on a live linux VM should work.
