This article describes how to add xVM DomU support to a Solaris Live CD distribution (Note: xVM is Xen for Solaris). Due to the fact that CDROMs are read-only this can only be done after installing the distribution to a harddisk. For this example we use the OpenSolaris distribution MilaX 0.3.2 but the instructions should also work for other OpenSolaris distributions (like for example Belenix).
