SYMPTOMS
After you transfer a Red Hat Linux 7.2-based guest PC disk image from an Intel Pentium IV-based host computer to an AMD Athlon-based host computer, you cannot start the Linux guest operating system. When you try to start the guest operating system, you receive an error message that is similar to the following error message:

An unrecoverable processor error has occurred.

Note This behavior also occurs when you transfer the guest PC disk image from an Athlon to a Pentium IV-based host computer.



CAUSE
This behavior occurs because when you install Red Hat Linux 7.2 on the guest PC, the installation program installs a kernel that is optimized for the host computer's system architecture. Therefore, the Linux kernel does not start successfully when you try to run the guest PC disk image on a host computer that is based on a different processor architecture.



RESOLUTION
To resolve this issue, remove the optimized Linux kernel, and then install the generic kernel before you transfer the disk image to the host computer that has the different architecture. To do so, follow these steps:  Start the guest PC on the original host computer. Log on to the Linux operating system by using an account that has root permissions. Run one of the following commands, depending on the host computer architecture, to remove the optimized kernel:  For an Intel Pentium IV-based host computer:

rpm -e -nodeps kernel-2.4.7-10.i686.rpm

 For an AMD Athlon-based host computer:

rpm -e -nodeps kernel-2.4.7-10.athlon.rpm

  Run the following command to install the generic kernel:

rpm -e -nodeps kernel-2.4.7-10.i686.rpm

</li> Save the changes to the guest PC disk image.</li> Transfer the disk image to the new host computer.</li></ol>
