libvirtVirtualization is a technology that provides a way for a machine (Host) to run another operating system (guest virtual machines) on top of the host operating system.
This chapter introduces and explains the components and technologies you need to understand to set up and manage a Xen-based virtualization environment.
Linux container is a lightweight virtualization method to run multiple virtual units (containers, similar to the chroot environment) simultaneously on a single host. Containers are isolated with kernel Control Groups (cgroups) and kernel Namespaces.
None of the virtualization tools is installed by default.
Supported virtualization limits for XEN and KVM are available in the Release Notes (http://www.suse.com/releasenotes/).
