(I got the lists mixed up, sorry :P) You should be able to limit dom0 memory by editing grub.conf and add dom0_mem=1GB (or whatever ammount of memory you choose) to xen.gz line. I'm not sure how much memory an opensolaris dom0 should have at minimum, so you can try at 1GB, and reduce it gradually. 384 MB is safe for Linux, but opensolaris needs more. Note that this does not directly affects domU speed though. It would probably only get you several extra MB for domU, plus reduce (by a little) the time needed to startup domU (since dom0 wouldn't need to balloon-down memory). As for PV drivers, they should improve performance greatly. However to tell the truth I haven't had the chance to try out GPLPV with opensolaris dom0 in a long time. Last time I test, networking was broken. You should either try GPLPV (http://meadowcourt.org/downloads/), or Sun's own PV drivers (don't have the link handy though). -- Fajar _______________________________________________ xen-discuss mailing list [email protected]
