Specifying dom0 RAM in Xen – update

Another thing from the xen-users mailing list:

Apparently the way to specify the dom0 RAM at boot in Xen has changed. You should now specify the maximum memory – dom0_mem=2G,max:2G instead of dom0_mem=2G.

Also, a new addition to the Xen Best Practices suggests preventing Xen from auto-ballooning the dom0 memory down by changing autoballoon in /etc/xen/xl.conf to 0.
