    please consider updating the microcode on your host

    osde.info Expert

      HOST is RHEL 5U5

       

      # yum list micro*
      Loaded plugins: dellsysid, downloadonly, rhnplugin, security
      Installed Packages
      microcode_ctl.x86_64                                   1:1.17-1.50.el5                                   installed
      GUEST is OEL 5U6
      Feb 10 12:43:22.386: vcpu-0| The guest OS tried to update the CPU's microcode.
      Feb 10 12:43:22.386: vcpu-0| Since a newer microcode version exists, please consider updating the microcode on your host.

       

      is this anything to worry about ? or do i just have to wait for Red Hat to release RHEL 5U6 ?

            thanks i'd already noticed that one but it doesnt answer the problem for me

             

            i'm now thinking the message may be related to the way vmware fudges and mangles /proc/cpuinfo and how microcode_ctl may interpret this info !

            or
            does the oracle rpm package microcode_ctl.i386 1:1.17-1.52.el5 really contain new microcode for the Intel Xeon CPU L5335 ?
