Dom0 Disaggregation
From Xen
Dom0 Dissaggregation
The Dom0 or control domain has traditionally been a monolithic privileged virtual machine. However, the original intention was for Dom0 to be carefully broken into several privileged service domains - termed Dom0 disaggregation. Qubes OS, Citrix XenClient, and Xoar have made the case for more disaggregation of Dom0 for purposes of better security, reliablity, isolation, and auditability.
