Xen: Install xen in Ubuntu

-Install and configure xen in Ubuntu

Lab environment:

Operating System: Ubuntu 12.04.4 lts x86_64

Kernel version: 3.2.0-23-generic

Install bridge-utils:

apt-get  install bridge-utils

Configure the bridge network (use static IP address, where the real IP address is replaced by x. x ):

# The loopback network interfaceauto loiface lo inet loopback# The primary network interfaceauto eth0iface eth0 inet static        address X.X.X.X        netmask 255.255.255.128        gateway X.X.X.Xauto eth0:0iface eth0:0 inet static        address X.X.X.X        netmask 255.255.255.128auto eth1iface eth1 inet manualauto xenbr1iface xenbr1 inet static    address 10.20.20.20netmask 255.255.255.0bridge_ports eth1bridge_stp off

Use apt-get to download and install:

 apt-getinstall xen-hypervisor-4.1-amd64 xen-utils-4.1 xenwatch xen-toolsxen-utils-common xenstore-utils

Modify the startup Item after installation:

sed -i‘s/GRUB_DEFAULT=.*\+/GRUB_DEFAULT="Xen 4.1-amd64"/‘ /etc/default/grubupdate-grub2

Modify xend configuration (/etc/xen/xend-config.sxp)

Use the bridging method based on my network configuration. Modify the following:

(network-script ‘network-bridge netdev=eth1‘)

To ensure smooth network connection, you need to configure the following:

Add NAT:

/sbin/iptables-t nat -A POSTROUTINGi -s 10.0.0.0/8 -o eth0 -j MASQUERADE

Enable IP forwarding:

vim/etc/sysctl.confnet.ipv4.ip_forward= 1sysctl -p

Now, the basic configuration of xen is OK.
