    enbaling all the CPU's


    We had RHEL 2.1 AS with 4 CPUs but only 1 CPU was enabled. Even after upgrading it to RHEL 5, it is still enabling only 1 CPU. Do we need to run any additional rpm to enable all 4 CPU? The process followed was

    booted the Vm with LINUX 5 cd and entered "linux upgradeany"
    then it prompted the kernel to be upgraded and we selected the kernel
    to upgrade the LINUX to RHEL5.

    RHEL5 should use all CPU's by default. Are all CPU's enabled in the BIOS?

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    Are you talking about a virtual machine guest OS, or the host system? From your original posting, it looks to me like you are only getting 1 CPU in your VM. You might need to upgrade your virtual machine manager software to support more than one CPU for a guest OS.
    Sometimes, real fast is almost as good as real time.
