The next step in the virtualization setup process is to specify the virtualization method. When using QEMU or KVM, the only method supported is full virtualization. In Xen you can use either paravirtualization or full virtualization. The CPU architectures supported are i686, x86_64, PPC, SPARC, MIPS, and MIPSEL. If you have the KVM kernel module loaded, check the box for enabling kernel / hardware acceleration.
After specifying the virtualization method, the next step is to select the media and operating system type. The media can either be an ISO image or a CD/DVD drive. The operating system types listed are Linux, Microsoft Windows, Novell Netware, Sun Solaris, and Other. The OS variants for Linux include Fedora Core 4-6, Other Linux 2.6 kernel, Red Hat Enterprise Linux 4, Red Hat Enterprise Linux 5, Red Hat Enterprise Linux AS 2.1/3, and SuSE Linux Enterprise Server. OS variants for Microsoft Windows include Windows 2000, Windows Server 2003, Windows Vista, and Windows XP. Other variants include FreeBSD, MS-DOS, Solaris 9, and Solaris 10. Depending upon what operating system you intend on virtualizing, select the most appropriate type and variant.
