Some friends of ours over at 360is have come up with a clever way of displaying their capabilities and services around XenServer: a free administration poster. This rounds up such things as internal networking diagrams, essential commands, guests & templates and hardware essentials in an easy-to-read overview, ready to print out and keep handy in a XenServer-based data-centre. There are 2 versions of the poster, a printer-friendly black & white option or, as Nick describes it, a "printer toner industry stimulus package": the midnight version.
