Migration to a Different Processor

VMware Workstation: VMware recommends you do not migrate a Red Hat Linux

Advanced Server 2.1 virtual machine between hosts when one host is running on an

AMD processor and the other is running on an Intel processor.

During installation, Red Hat Linux Advanced Server 2.1 chooses a kernel that is

optimized for the specific processor on which it is running. The kernel may contain

instructions that are available only on that processor. These instructions can have

adverse effects when run on a host with the wrong type of processor.

Thus, a Red Hat Linux Advanced Server 2.1 virtual machine created on a host with an

AMD processor may not work if migrated to a host with an Intel processor. The reverse

is also true: a Red Hat Linux Advanced Server 2.1 virtual machine created on a host

with an Intel processor may not work if migrated to a host with an AMD processor.

This problem is not specific to virtual machines and would also occur on physical

computers. For example, if you moved a hard drive with a Red Hat Linux Advanced

Server 2.1 installation from an AMD machine to an Intel machine, you would

experience problems trying to boot from that drive.
