Installation of xen virtualization environment in xen virtualization series (I)

Xen supports RHEL, CentOS, and OEL5.X. RHEL6.X is not supported by default, but you can also install it by installing the xen source. This article uses OEL5.8 x64 for Environment configuration. In the future, we will publish a series of articles on xen configuration in plain text. Here we will not discuss the concepts of semi-virtualization and full virtualization. We will only talk about the actual situation and make a summary of xen learning.

1. Operating System Installation

OEL5.8 X64 is used for installation. The GUI, Development Kit, development library, and old software development kit are selected during installation.

2. Configure the yum Source

Note: Installing the source is the easiest.

# Cd/etc/yum. repos. d
# Wget http://public-yum.oracle.com/public-yum-el5.repo
# Vi public-yum-el5.repo

# Change the corresponding enable to 1, as shown in
