Install xen in yum in centos 5.3

Xen source code installation has encountered some problems, and now there is no time to solve them one by one. I will try again later. Empty write log first

Use Yum to install the package group of virtualization. The virtualization package group contains all the xen components. Therefore, you only need to use Yum groupinstall to install all the xen components. Mainly include:
Xen: This is the main program of xen and the essential component for executing xen.
Kernel-xen: This is the Linux kernel package for xen rewriting.
Libvirt: provides the link library and management tools required for virtualization.
Python-embedded inst: a tool for creating and installing virtual machines using a text interface.
Virt-Manager: A graphical xen integrated management tool.
[Root @ localhost ~] # Yum-y groupinstall 'canonicalization'
Loaded plugins: fastestmirror, priorities
Loading mirror speeds from cached hostfile
