Various virtualization solutions have a common need for ancillary
utilities which manage storage, snapshotting, monitoring, etc.

Both KVM and Xen derive their device and machine model from qemu and
inherit a lot from it's approach to emulation/virtualization. This
package is hence a good place to have qemu related tools reside.
Additionally, any other utilities which have use across the various
virtualization solutions available have a home here.
