How to install ipython on XenServer and test XAPI

We've been using the more user friendly shell to interact with python before: ipython. The example below are showing first how to install and enable EPEL repository to be able to install ipython. Next we are going to write a simple XAPI demo program.

Install ipython
  • Find the distro your XenServer is based on
cat /etc/issue.net
CentOS release 5.7 (Final)
Kernel \r on an \m
  • Check enabled repository 
yum repolist
  • From the EPEL install the relevant rpm packets that will add new repository to your yum

rpm --force -i http://www.mirrorservice.org/sites/dl.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
  • Update the repo info
yum list 
yum list | grep ipython
  • Install ipython
yum install ipython.noarch
  • Start and verify that ipython is working fine
ipython

In [3]: import sys
In [4]: sys.version
Out[4]: '2.4.3 (#1, Sep 21 2011, 20:06:00) \n[GCC 4.1.2 20080704 (Red Hat 4.1.2-51)]'
