Two ways to install Xen on Centos6.5

One, through the official CentOS solution (Https://wiki.centos.org/HowTos/Xen/Xen4QuickStart)

1. See if the host supports PV (semi-virtualized) or HVM (full virtualization)

# Cat/proc/cpuinfo | Egrep-o ' (PAE|VMX|SVM) '

PS: If you see PAE in the output, then the CPU supports para-virtualization, if the output has both PAE and VMX/SVM (note: VMX is INTEL,SVM for AMD), then CPU support is fully virtualized

2. connect the Xen4centos database to your machine so that it can be installed easily

# yum Install Centos-release-xen

PS: If the installation has the following error, you can try to resolve

# yum Remove redhat-release-server-6server-6.5.0.1.el6.x86_64

# yum Install Centos-release-xen

3, you have now added the Xen4centos repository to the Yum source, then install Xen

# yum Install Xen

4. Execute the/usr/bin/grub-bootxen.sh script to complete the update grub.conf operation

# bash/usr/bin/grub-bootxen.sh

5. View Grub.conf File contents

6, restart the system

# reboot

7. Review the kernel version of the virtual machine after rebooting the system, and view information about Xen

# Uname-r

# XL Info or (XM Info XM command needs to rely on xend service, xen4.4 Previous version support XM, later version only XL)

Second, the official solution via Xen Made Easy (http://xen.crc.id.au/support/guides/install/)

1, install a third-party Xen Yum Source

# yum Install http://au1.mirror.crc.id.au/repo/kernel-xen-release-6-5.noarch.rpm

2. Installing the Bridge tool

# yum-y Install Bridge-utils

3, install Xen

# yum Install Xen45

4. Verify that the installation is successful

# ls-l/boot/xen.gz

5. Install the Xen kernel

# yum Install Kernel-xen

6, restart

# reboot

7. Review the kernel version of the virtual machine after rebooting the system, and view information about Xen

# Uname-r

# XL Info or (XM Info XM command needs to rely on xend service, xen4.4 Previous version support XM, later version only XL)
