Known Issues

Guest Screen Saver

VMware Workstation or VMware GSX Server: On a Linux host with an XFree86 3.x X

server, it is best not to run a screen saver in the guest operating system. Guest screen

savers that demand a lot of processing power can cause the X server on the host to

freeze.

Migration to a Different Processor

VMware Workstation or VMware GSX Server: VMware recommends you do not

migrate a Red Hat Linux 8.0 virtual machine between hosts when one host is running

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

During the Red Hat Linux 8.0 installation, Red Hat 8.0 chooses a kernel that is

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

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

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

Thus, a Red Hat Linux 8.0 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 8.0 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 8.0

installation from an AMD machine to an Intel machine, you would experience

problems trying to boot from that drive.

Message about “Tainted” Driver

VMware ESX Server or VMware VirtualCenter: When a Red Hat Linux 8.0 guest

operating system loads the vmxnet networking driver, it reports that the driver is

tainted. This does not mean that there is anything wrong with the driver. It simply

indicates that this is a proprietary driver, not licensed under the GNU General Public

License.
