I needed a couple of virtual hosts and a virtual network to complete a Puppet course. I can play with an 8-core 32GB RAM server, having a 1GB/s network connection. It runs Wheezy, and there's a 73GB disk free. So I put Xen on it. Here's how I did it.
(First run egrep '(vmx|svm)' /proc/cpuinfo to see whether this machine supports hardware virtualization so we may run Windows easily.)
apprentice@server:~$ sudo apt-get install xen-linux-system xen-tools debootstrap cdebootstrap openxenmanager virt-top libvirt-bin virt-goodies virtinst
apprentice@server:~$ sudo dpkg-divert --divert /etc/grub.d/08_linux_xen --rename /etc/grub.d/20_linux_xen
apprentice@server:~$ update-grub
Without the following, xend doesn't start.
apprentice@server:~$ sudo sed -i 's/xend-unix-server\ no/xend-unix-server yes/g' /etc/xen/xend-config.sxp
apprentice@server:~$ sudo reboot
