2.1 Oracle VM Server

Oracle VM Server includes an updated version of the underlying Xen™ hypervisor technology, and the Oracle VM Agent. It also includes a Linux kernel with support for a broad array of devices, file systems, and software RAID volume management. The Linux kernel is run as dom0 to manage one or more domU virtual machines, each of which could be Linux, Solaris or Microsoft Windows. Figure 2–1, "Oracle VM Server" shows the components of Oracle VM Server.
