    33vconsole runs [http://www.xensource.com Xen].  Instances of Xen are configured in {{{/etc/xen/*.cfg}}} and their raw images in {{{/var/img}}}.  The Xen host ({{{dom0}}}) is configured in /etc/xen/*.sxp and by our custom bridge creation scripts in {{{/etc/xen/scripts/*-orbit}}}.  We have plenty of disk, so we don't bother using LVM2 to share images yet -- each {{{domU}}} has its own full image.  Most of the instructions we needed are at [https://help.ubuntu.com/community/XenOnUbuntuBinaryInstall].  Don't use the Xen packages Edgy/universe, run 6.06 like a sensible Ubuntu admin, and install the xensource binary tarball over it using the given script.  Seriously.

    5 From [http://tx.downloads.xensource.com/downloads/docs/user/#SECTION02220000000000000000 The Xen User Guide]:
    6   "... MAC address from the range 00:16:3E:xx:xx:xx, assigned by IEEE to !XenSource as an OUI (organizationally unique identifier). !XenSource Inc. gives permission for anyone to use addresses randomly allocated from this range for use by their Xen domains."

    8 We use specific MAC addresses, and manage them with DHCP as if they were otherwise physical devices.
