Linux disk Virtualization 1. LVM (Logical Volume Manager): The logic scroll bar administrator. LVM can combine the partions (or disks) of several entities into a large independent disk (VG) through software ), then, the large disk is divided into separate slots (LV), which can be mounted and used. 2. PV (Physical Volume): the entity scroll bar. Our actual partition needs to be adjusted by the system ID call

By Virt-manager or modifying the/etc/libvirt/qemu/server.xml file of the KVM virtual machine, the new disk is deleted, and the original drive bus mode is changed to Virtio,xml mode as follows: "It's more convenient to pass the Virt-manager." 7.

What LXC can do:You can bind specific CPUs and memory to a container, assign a specific percentage of CPU time, IO time, limit the amount of memory that can be used (including memory and swap space), provide device access control, and provide an independent namespace (network, PID, IPC, MNT, UTS).The default LXC configuration is to isolate PIDs (process) SysV IPC (interprocess communication), and mount points. If you want to run sshd, you must provide
LXC container Virtualization After some tossing, I initially deployed LXC virtual on my work notebook. This is a very lightweight virtual solution, especially suitable for testing environments with limited hardware and a good environment for our system administrator technical training.

This is a creation in Article, where the information may have evolved or changed. The research on the container network has been interrupted for some time due to the reasons for the exchange of work in 2016. With the current project to kubernetes application in depth, I feel that before the shallow understanding of the container network is not enough, the container
1. Basics: The concept of Linux namespaceThe Linux kernel has introduced the concept of namespace from version 2.4.19 onwards. The goal is to have a particular global system resource (Resource) through an abstract approach so that processes in namespace appear to have their own isolated global system resource instances (the purpose of each namespace are to Wrap a particular global system resource in an abst

Guide Fundamentally, almost all of the major software, even open-source software, was designed before the advent of mirror-based container technology. This means that putting the software in a container is equivalent to a platform migration. This also means that some programs can be easily migrated, while others are more difficult. I carried out mirroring-based
