linux container virtualization

Quick understanding of Docker-container-level virtualization SolutionsSimply put , Docker is a lightweight VM solution built on top of LXC , based on process containers (processcontainer) By analogy with the transport of goods in the real world , in order to solve the problem of transporting goods of various types and sizes in various transport vehicles , we invented the

; Because of its lightweight features, docker can help applications implement real-time cloud migration, which will certainly attract more people to use cloud services. Therefore, it deserves to be the star of cloud computing. Dalong, star of cloud computing in China After being fully recognized by major technology vendors, ncomputing, an international desktop virtualization leader, has joined hands with Dalong to become a technical vendor. Dalong clo

operating systems, it seems that they all run on their own hardware, maybe Linux, maybe other operating systems. Nowadays, virtualization may refer to operating system virtualization, storage virtualization, or virtual devices. For operating system virtualization, you will

. Essentially, he started a Linux Container using LXC at the bottom, isolating applications running in different Container through mechanisms such as cgroup, rights management, and quota allocations. Each container has its own separate namespaces (i.e., resources) that include: PID process, MNT file system, net Networ

. The earliest true overall application virtualization hardware platform was the IBM CP-40 system, which was used in commercial applications at the end of the 1960s S. Virtualization includes multiple layers, such as hardware virtualization, which directly supports the software environment from the underlying hardware platform. The other is operating system

environment. It has a slightly higher performance than full virtualization. Like Xen. Because the kernel of the managed system needs to be changed, Xen does not support the win virtual machine.There are also hardware-assisted virtualization, which is a host hardware architecture that provides support for virtualization to some extent. Such architectural support

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.
