Xen is a “virtual machine hypervisor” for the x86 platform and allows multiple operating systems to run simultaneously on a single system without drastically impacting performance. For more information about Xen and its community, we refer you to this one and this one pages. Currently only Linux and NetBSD are supported as host systems, but work is underway to fully support other operating systems, such as Solaris. The developers have released Xen 3.4.0 with the following announcement:
