I have found setting dom0_mem to 2G (with zfs in dom0) works pretty well as long as you don't balloon down. If you want to set dom0_mem to 1G, you should limit the amount of memory zfs uses. e.g. set the following in /etc/system. set zfs:zfs_arc_max = 0x10000000 MRJ _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
