The problem I've seen with this feature is that Windows guests end up taking all of their available memory once they are up and running. For example, booting Windows XP in KVM 82 show a steady increase in memory. Then about the time the login box is about to appear, memory usage jumps to the maximum allowed to the VM (512 MB in this case). I remember reading somewhere Windows would try to initialize all memory during boot, causing KVM to allocate all memory. VMware, however (and I don't know about VirtualBox) knows about this and works around it, making sure memory isn't all allocated during the Windows boot process. Would there a way to work around the Windows memory allocation issue in KVM as well? -- 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
