n Dedicated hypervisor
l The minimum OS needed to run/manage virtual machines
l Well defined management interfaces/APIs
n Small footprint
l ~120MB image size
l 750MB disk space required for installation
n Built from software distributed as part of RHEL
l Builds upon well tested base OS
l Supports the same hardware as RHEL
l Leverages hardware certification and partner testing
n Utilizes KVM (Kernel-based Virtual Machine)
n Includes libvirt & vdsm for virtual machine management
KVM (Kernel-based Virtual Machine)
n Linux based hypervisor for running virtual machines
n Integrated into core Linux kernel as a kernel module
n Uses qemu to provide device emulation
n Requires hardware virtualization support on the CPU
l Intel – Intel VT
l AMD – AMD-V
n Supports a wide variety of guest OSes including:
l Linux (RHEL, Fedora and other distributions)
l Microsoft Windows (7, XP, Server 2003, Server 2008)
n Does not require special guest software or kernel
n Enhanced I/O performance provided by para-virtualized network and disk drivers (virtio)
