Linux Virtual Machine xen Installation

Article Title: linux Virtual Machine xen installation. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.

Installation environment:

Install centos 5 in VM6 and then install Virtual Machine xen under centos 5

Second, install another linux centos Virtual Machine System on the xen Virtual Machine

Just like installing windows on VM6, and installing VM software under windows

Second, installing another windows System in the vm is similar.

1> first, create a virtual machine in VM6, add two disks, one for installing the host machine, and one for reserving the XEN virtual machine.

2> install the xen package and vsftp package in YUM on the host machine. (It is best to install these two components when installing the system. You can also install them by adding/deleting programs, but you need to modify the yum configuration)

[Root @ localhost ~] # Yum-y install xen

[Root @ localhost ~] # Yum-y install vsftpd. i386

Install yum install gnome-applet-vm.i386

The grub Startup menu has been started by the xen kernel.

Vi/boot/grub. conf

# Boot =/dev/sda

Default = 0 (1 is changed to 0 to start the xen kernel)

3> run the xm list command to check whether the Domain has been started.

[Root @ localhost ~] # Xm list

Name ID Mem (MiB) VCPUs State Time (s)

Domain-0 0 778 1 r ----- 85.4

4> Mount cdrom to the FTP directory and enable Anonymous ftp users.

/Etc/init. d/vsftpd start # start ftp

[Root @ localhost ~] # Mount/dev/cdrom/var/ftp/pub/# mount the disc to the ftp

Mount: block device/dev/cdrom is write-protected, mounting read-only

5> use the xm command line to create a virtual machine

[Root @ localhost ~] # Virt-install (the parameter -- prompt is required for the new xen version, and the hard disk size parameter is set. This parameter is not set for the old version.

What is the name of your virtual machine? Vm1 # Virtual Machine name vm1

How much RAM shoshould be allocated (in megabytes )? 400 # allocate a minimum of 400 mb of memory to the VM

What wocould you like to use as the disk (file path )? /Dev/sdb1 # sdb is the second Hard Disk

Wocould you like to enable graphics support? (Yes or no) no # do not enable graphical support

What is the install location? Ftp: // 192.168.1.237/pub/# Fill in the local FTP address, provided that the CDROM has been mounted to this FTP directory and anonymous users are enabled.

We can see that the kernel of the installation file has started!
