Re: [Xen-users] Disable memory balloon in dom0

good safety net.

Perhaps I am just mis-understanding. I take this to mean that domU can
steal memory from dom0 up until dom0 gets to the min-mem threshold. And
according to the config comments setting to 0 makes dom0 not balloon. So
I read that as domU can not ever steal memory from dom0.
