Ubuntu11.10 install xen

My machine's operating system: Linux Ubuntu 3.0.0-11-generic # 18-ubuntu SMP Tue Sep 13 23:38:01 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux

The linux3.0 kernel already supports xen, so you don't need to compile the kernel anymore (for those systems that support the kernel, you don't need to re-compile the kernel ).

Step 1:

Install required software packages

Install the required software packages for compiling xen and Linux xen kernel:

 
$ Sudo apt-Get install GCC g ++ make patch libssl-dev Bzip2 gettext \ zlib1g-dev Python libncurses5-dev libjpeg62-dev libx11-dev libgcrypt11-dev PKG-config bridge-utils BCC bin86 libpci-dev \ libsdl-Dev python-dev texinfo libc6-dev UUID-dev bison flex fakeroot \ build-essential crash kexec-tools makedumpfile libncurses5 \ libncurses5-dev IASL gawk
 

Step 2:

Run the command: APT-cache search xen.
Then select to install tools related to xen. What I installed is:
$ Sudo apt-Get install xen-tools xen-utils-common xenomai-Doc xenomai-runtime xenwatch libxen-dev libxenstore3.0 xen-docs-4.1 xen-hypervisor-4.1-amd64 xen-utils-4.1 xenstore-utils

Step 3:

Add to Automatic startup script

Update-rc.d xend defaults 20 21

Update-rc.d xendomains defaults 21 20

Step 4:

Restart the machine, select a kernel with xen to start, and then enter the system,

Check whether the xen has been successfully installed:

 
$ Sudo XM listname ID mem vcpus state time (s) domain-0 1879 2 R ----- 6.6
 

The above information indicates that the installation is successful and can be used properly.
