At least with the kvm setup I have, there is no way to overcommit memory, other than to use the hosts swap. Things are pretty tight memory wise for me, I'm hoping KSM in 2.6.32 will help alleviate matters some what. -- Thomas Fjellstrom tfjellstrom@xxxxxxx -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
