XenClient was designed from the ground-up to be open and extensible. This starts by using open source technologies such as Xen, the Linux kernel and many more technologies. Next XC employs a unique Service VM architecture allowing the system to be extended via functional disaggregation. These Service VMs are generally small purpose built VMs that provide new services to the platform or to the local virtual ...
