Use virt-install to create an xen VM

Use virt-install to create an xen Virtual Machine [root @ gmnode14 vm01-CentOS-5.5] # virt-install-N vm01-CentOS-5.5-r 1024 -- vcpus = 4-F vm01-CentOS-5.5.img-s 20 -- nographic-l NFS: 10.10.113.14:/opt/centos/mirrors/5.5

-------------------------

Virt-install Parameter Parsing:

-NVm01-CentOS-5.5#Virtual Machine name, here our name is vm01-CentOS-5.5

-R 1024 #The maximum memory size of the VM, in MB. Here our memory is 1 GB

-- Vcpus = 4 #Number of Virtual Machine CPUs. Here we have 2

-FVm01-CentOS-5.5.img#Virtual Machine virtual hard disk name, we use vm01-CentOS-5.5.img here

-- Nographic #Do not install graphical interfaces.

-LNFS: 10.10.113.14:/opt/centos/mirrors/5.5#The path of the system image. Xen only supports FTP/HTTP/nfs

-------------------------

After creation, the image file vm01-CentOS-5.5.img is generated under the current directory;

Generate the Virtual Machine profile vm01-CentOS-5.5 under the/etc/xen directory;
