Red Hat Enterprise Linux 5.4

now includes full support for the Kernel-based Virtual Machine (KVM) hypervisor on x86_64 based architectures. KVM is integrated into the Linux kernel, providing a virtualization platform that takes advantage of the stability, features, and hardware support inherent in Red Hat Enterprise Linux.

Note
Xen is the default hypervisor that is shipped with Red Hat Enterprise Linux. As such all configuration defaults are tailored for use with the Xen hypervisor. For details on configuring a system for KVM, please refer to the Virtualization Guide.

Important
Xen based virtualization is fully supported. However, Xen-based virtualization requires a different version of the kernel to function. The KVM hypervisor can only be used with the regular (non-Xen) kernel.

Warning
While Xen and KVM may be installed on the same system, the default networking configuration for these are different. Users are strongly recommended to only install one hypervisor on a system.

PAYG GoGrid Cloud Hosting

Every GoGrid account includes FREE hardware F5 load balancing. It takes less than 5 minutes to setup F5 load balancing and the process is completely automated. Three Virtual IP (VIP) addresses are included. A VIP is the IP address the F5 load balancer uses to direct traffic to servers.

F5 Load balancing can be used to spread internet traffic across two or more servers. In the event a server crashes, the load balancer will redirect all traffic to the remaining online servers preventing application downtime. If your web application sees a drastic increase in internet traffic adding additional servers to the load balancer is simple and ensures your servers will not crash due to an overload of incoming HTTP requests.
