After that you are well on the way to a full upgrade to Testing. Markus: I can't use dom0-min-mem 0, for my Play Machine I'm running Xen with 256M of physical RAM. It's impossible to give the DomU enough RAM for good performance without having less RAM for the Dom0 than is sufficient for booting the system. For my more serious Xen servers I usually leave the dom0-min-mem at it's default setting which prevents it from decreasing too much.

Also in my lenny setup i set "(dom0-min-mem 0)" in /etc/xen/xend-config.sxp to be save there will no down sizing of ram.
