-	~~This~~ can be done by editing /etc/xen/~~xend-config~~.~~sxp~~ and ~~modifying the "dom0-min-mem" option to (dom0-min-mem 512) and also change the "enable-dom0-ballooning" option to (enable-dom0-ballooning no)~~. ~~These options~~ will ~~make sure xend never takes any~~ memory ~~away from~~ dom0.	+	If you are using the [[XL]] toolstack then this can be done by editing /etc/xen/xl.conf and setting autoballoon=0. This will prevent [[XL]] from ever automatically adjusting the amount of memory assigned to dom0.

-	After making these changes to grub.conf and to xend-config.sxp, reboot the system. After reboot you will notice dom0 has only 512 MB of memory, and the rest of the RAM is available in Xen hypervisor as a free memory.

New page

This page lists a number of things we could do to make the default experience of xapi on debian more smooth

# "xe" could detect when it's talking to another webserver (e.g. apache) and print something more helpful than "Server internal error."
# the NFS SR could detect when "nfs-common" hasn't been installed and prompt to install it (or it could depend on it)
# the regenerate templates md5 stamp shouldn't be written if the regenerate templates fails (eg due to a dead xapi)
# xapi startup should print a more useful message if libXc doesn't work because the "xen" init.d script hasn't done the necessary setup
