In the traditional hypervisor Virtual Machine (VM) approach that is used by VMware's ESX and open-source options like Xen and KVM, a host operating system runs the hypervisors, which then in turn requires an operating system of its own for VMs. In theory, this should "just work" so long as the guest VM you are working with has kernel drivers in it for virtio. This usually results in a higher pricing. Xen is opensource, while XenServer is based upon Xen, it’s owned by Citrix. cfg file tells Xen to use PyGRUB to boot the kernel - this is one of the special tricks requried for PV guests. It has become incredibly popular and common in the last few years. The output shows two NUMA nodes (also know as NUMA cells), each containing four logical CPUs (four processing cores). It consists of a loadable kernel module, kvm. The theory is that if, for example, Xen is unavailable but the machine is running an OpenVZ kernel, then we should not try to connect to the Xen hypervisor since that is obviously the wrong thing.
