Hi!

The CNA is a virtualized operating system that virtualizes underlying physical hardware resources into virtual resources and provides the virtual resources for upper-layer VMs.

Hypervisor: It is an intermediate software layer between the operating system and hardware. It is responsible for CPU scheduling and memory allocation between VMs. It abstracts the hardware of VMs and controls the command execution of each VM. However, it does not process network I/Os and is the executor of virtualization.

Domian 0: Linux Kernel is the only VM running on Xen Hypervisor. It has the permission to access physical I/O resources and interacts with other VMs running on the system. Domain 0 must be started before other domains are started, the domain0 is used to capture and process I/O information exchanged between the Domain U and underlying hardware.

Domain U: All paravirtualized VMs running on the Xen Hypervisor are called Domain U PV Guests, which run the operating system whose kernel has been modified, such as Linux, Solaris, and FreeBSD. All virtual virtual machines (VMs) are called Domain U HVM Guests. Operating systems that do not require kernel modification (such as Windows) are running on the VMs.
