Just in case the author (or further readers like me) haven't seen the referenced thread, there's word that HVM 64-bit domains are still underway, so for unmodified guests we must use the 32-bit versions.
See: http://opensolaris.org/jive/thread.jspa?messageID=182165&tstart=0 BTW, can we force a 32-bit Guest domain boot (newly created or old) with a 64-bit dom0 xVM kernel loaded and running? Is it in FAQ somewhere? No?.. Beside giving the link, I have some questions of my own, concerning xVM performance and general compatibility: In my personal experience, the performance seems appaling when it's working at all :( It's worse with the idea of a 45% RAM footprint of Xen dom0, compared to 200-500Mb of VMWare ESX Server 3.0.1's Console. On good big servers, 45% is a lot. We did some tests at work trying to install some Xen virtual machines on Sun X4600 (snv_b77), and see if [Open]Solaris+xVM(+ZFS+...) is a reasonable replacement right now for VMWare ESX... Does anyone have near-hardware performance? Maybe just a few times worse? Which OSes andversions? For our integrations, Solaris 10, RHEL 3-5 and Windows 2000/2003/XP are of primary interest. With the problems we had, I wonder: did we do something (many things) wrong, or does everyone suffer similarly, and that's just the way things are right now? ;) Here's some results of the few attempts so far (Solaris 10U4 works well, others suck at best): While we did get Windows XP SP2 (32-bit) to boot and even go on configuring in graphics mode (first reboot), it took a couple of hours to get to the TCP/IP Settings screen (Setup will completein approximately 29 minutes)... BTW, VNC screen loses somepart of the display bottom side (due to unusual resolution in the Windows installer); can it possibly adapt to VM resolution changes? Windows 64-bit releases failed (froze fordays) in the text mode part, Starting Windows - as expected, I see now. I did get a Solaris 10u4 8/07 running in a "--vnc --hvm" installation mode, but in the textmode installer over VNC (got a corrupted white screen in graphical attempts). Got the full install okay (End User + OEM packages), booted up all the way to the JDS. Apparently it works as 32-bit, without an amd64/boot_archive and amd64/multiboot parts yet, and seemed reasonably fast working. I did *not* get a guest snv_b77 running (best I did was text mode and Signal 11 in install-solaris after Reboot Warning screen).
