This is still a
fairly new sharing mechanism. It has the potential to provide easy installation and
configuration of large blocks of virtual machines at the same time by using a standard
definition of a virtual machine. The virtualization management system that you
are using will need support; currently only the Enomalism Virtualization Console
(http://www.enomalism.com/) supports this feature. It will be interesting to see
whether it will be supported by any other management applications going forward.
Summary
In this chapter we discussed some of the newer ideas that are gaining ground
around Xen.
libvirt: A great API that simplifies access to virtualization instances in a
vendor/hypervisor independent way.
VMcasting: A new and innovative way of transferring virtual machine
images from the server to the client using the RSS 2.0 format.
