As per yesterday's flag day notice "Solaris Nevada now supports the xVM platform on x86 and x64 systems."
http://www.opensolaris.org/os/community/on/flag-days/pages/2007091801 This is exciting (xVM == Xen in OpenSolaris). Also, for those who build ON, the minimum for building the gate is now bumped to B54. -Shiv
