Abstract
This Guide contains information on configuring, creating and monitoring guest operating systems on Red Hat Enterprise Linux 5, using virsh, xm, vmm and xend.
If you find an error in the Red Hat Enterprise Linux Virtualization Guide, or if you have thought of a way to make this manual better, we
would like to hear from you! Submit a report in Bugzilla (http://bugzilla.redhat.com/bugzilla/) against the product Red Hat Enterprise Linux and the component Virtualization_Guide.
