virtual machine to run.
Also, sometimes you need to link several closely related Docker, so that when hyper allows you to put them in a virtual machine, through Mount namespace isolate the filesystem, this is called Pod, this concept comes from kubernetes.
One more thingHyper also has some additional benefits, for a virtual machine-based private cloud architecture, using Hyper, allows the existing software stack for virtual machines to migrate more smoothly to the containerized direction. Fur
through a combination of its hypervisor and a specially privileged xen-modified kernel that is used to manage, monitor, and administer all other xen virtual machines running on a specific piece of hardware. thisSpecially privileged xen kernel is known as domain0.
As mentioned above, xen uses hypervisor and domain0 to manage access to memory and hardware resources.
From Wikipedia: http://en.wikipedia.org/wiki/Hypervisor
1. Definition: A piece of computer software, firmware or hardware that creates and runs virtual machines.Alias: Virtual Machine Manager (Vmm)
2. Two types of hypervisor (depending on whether or not they are directly running on the hardware)
Type I: Runs directly on hardware, such as Citrix xenserver, VMWare ESX/esxi
Type II: Run on the operatin

According to Wikipedia: "Hypervisor or virtual machine Monitor (VMM) is the software, firmware, or hardware that creates and runs virtual machines."
In layman's terms, hypervisor is a way of separating the operating system from the hardware abstraction, so that the hardware of host machine can run one to multiple VMS at the same time as guest machines, enabling these VMs to efficiently share host hardware
VMware workstation software needs to rely on the host operating system.VMware vsphere is a VMware company that offers a server virtualization solution that can be installed and run directly on naked machines on a standalone system.Both VMware vsphere hypervisor and VMware vsphere are installed directly on physical machines and are virtualized dedicated operating systems using the Linux kernel.Typically, VMware vsphere, also known as Esx,vmware vsphere
OpenStack is more than 4 years old, and each new version can meet some requirements and solve some problems. One of the biggest questions asked by enterprise users is: Can the same OpenStack cluster support multiple virtualization technologies at the same time (mutil-hypervisor)? the answer is, of course, yes!. Before we explain how to configure mutil-hypervisor, we need to understand what mutil-
