Introduction to Xen and introduction to virtual xen 1. Introduction to related knowledge: 1> common disk I/O schedulers: CFQ: completely fair queue algorithm; Deadline: deadline algorithm; Anticipatory: sequential read/write queue algorithm/Expectation Algorithm; NOOP: no operation, the simplest scheduling algorithm; 2> how to replace the I/O Scheduling Algorithm: the default algorithm is CFQ; /Sys/block/

Determine through related directories or files on the system Run: ls/proc/. Generally, the xen VPs and/proc Directo

This article describes the xen bridging network and the tools and methods that can be used when a fault occurs: The xen bridging network is flexible, but the logic and management aspects are still simple.. Bridging Device Bridge: xenbr0, xenbr1, etc. VIF, virtual network interface; generally named vif0.0, vif0.1, etc. Veth/ETH, a virtual network device. It is generally named eth0, etc.

Note: It is recommended to add a virtual disk file to increase disk space by adding LVM logical volumes to the virtual machine. The creation process is as follows. 1. DD Creates a disk file # dd If=/dev/zero bs=1024m count=4 >/data/test_01new.img 2. Turn off the test01 virtual machine 3. Modify the new virtual machine configuration file # vi/etc/xen/test01 # Modification Instructions: # (1) name # (2) UUID changes the last few data # (3)

The user space interface is xapi. py. The procedure of the member API functions of xapi. py is as follows: 1. Call connect and log on to xend through serverproxy RPC 2. Execute and execute func (* ARGs). Among them, func and ARGs are input parameters, and * ARGs indicates variable length parameters. Xapi. py supports the following API commands: Commands = {'Host-info': ('', 'Get xen host info '),'Host-set-name': ('', 'set host name '),'Pif

With the extensive use of virtualization technology, the use of virtualization thinking and start more, such as direct expansion of disk space in this case, I recommend a new disk to add a way to fit the normal physical machine to use the way. Another way to increase disk space is to extend the space of an existing disk directly, in this way. 1. View the virtual machine configuration file [Root@node1 data]# [Root@node1 data]# XM List Name ID Mem (MiB) Vcpus state time (s) Domain-0 0 1744 1

Preparing the Linux virtual system installation source #可以使用HTTP, FTP, or NFS are provided to Xen virtual machines for system installation. FTP is used here for installation, very simple and fast. 1) Installation of VSFTPD service # yum Install-y vsftpd # service VSFTPD Start 2 Mount CD to FTP anonymous directory # mount/dev/cdrom/var/ftp/pub/ Description: VSFTPD will support anonymous access after installation. 2. Create a virtual machine 1)
