biggest difference between hyper and Intel's release of Clear Linux in the previous period? For: The author is different, hmm. Clear Linux is a relatively pure direct replacement for container layers, compared to purely performance optimizations, we have some pod-type feature Clear Linux has a strong effect on certain kernel features and even CPU

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. Both

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

In summary,VirtioIs the abstraction layer in the semi-virtualized hypervisor located above the device.VirtioDeveloped by Rusty Russell, he aimed to support his own virtualization solutionLguest. This article introduces the semi-virtualization and analog devices at the beginning, and then exploresVirtio. The focus of this article is from the 2.6.30 kernel releaseVirtioFramework. Linux is the

(of which there is several specifications) was one aspect that needs to be addressed. PCI HotPlug permits PCI devices to come and go from a given kernel, which was ideal-particularly when considering migration of a VM to a hypervisor on a new host machines (devices need to is unplugged, and then subsequently plugged in at the new hypervisor). When devices is emulated, such as virtual network adapters, the
