8.6.4 Example of environment settings for a KVM-based virtualization environment
The following figure shows the system configuration that applies to the example of environment settings for a KVM-based virtualization environment.
The following shows an example of the environment settings for the primary system and the secondary system in this system configuration.
- Environment settings for the primary system (in a KVM-based virtualization environment)
-
- XML settings for the guest OS (excerpts from the sections related to the shared disk and SCSI controller)
-
