If your CPU support virtualization extensions (egrep 'vmx|svm' /etc/cpuinfo) than KVM is definitely the way to go: * KVM is part of upstream kernel since 2.6.20 -- supported by every up to date distribution. * VirtualBox may be OK, but it's the kind of "half-free" solution. There's an "Open Source Edition", but you have to use other editions for the full feature set. * Fully supported by libvirt (http://libvirt.org) which provides: - Remote management using TLS encryption and x509 certificates - Remote management authenticating with Kerberos and SASL - Local access control using PolicyKit - Zero-conf discovery using Avahi multicast-DNS - Management of virtual machines, virtual networks and storage - Portable client API for Linux, Solaris and Windows * Since libvirt also support Xen, this is great for mixed environment and migration (no need to change tools). * There's also virt-manager which is layered over libvirt and provide a GUI for the same management features and also secure console support (VNC encrypted over SSL or SSH) (http://virt-manager.et.redhat.com) Don't fall in the freebies trap -- חופשי זה יותר מחינם -- Oron Peled Voice: +972-4-8228492 [email protected] http://users.actcom.co.il/~oron "Without the wind, the grass does not move.
