Microsoft <i>Windows XP</i> is now supported as one of the operating system
types for experiment nodes in Emulab, in addition to FreeBSD and Linux.
Before booting the node at swap-in time, Emulab loads a fresh image of Windows
XP onto the experiment nodes in parallel, using our Frisbee service. Emulab
software automatically configures each Windows XP node, providing the expected
experiment user environment including: user accounts and Emulab SSH keys; remote
home, project, and shared directories; and network connections. <p>
