This is something that's plagued me for many versions. I've read the bug reports where this was marked as fixed back in version 12.x Currently with Kernel 2.6.37.4 64bit. modinfo kvm filename: /lib/modules/2.6.37.4/kernel/arch/x86/kvm/kvm.ko license: GPL author: Qumranet depends: vermagic: 2.6.37.4 SMP mod_unload parm: oos_shadow:bool parm: ignore_msrs:bool modinfo kvm-amd filename: /lib/modules/2.6.37.4/kernel/arch/x86/kvm/kvm-amd.ko license: GPL author: Qumranet depends: kvm vermagic: 2.6.37.4 SMP mod_unload parm: npt:int parm: nested:int cli used (drive image is raw format) - qemu-system-x86_64 -cpu core2duo -smp 2 -hda test -m 2048 -net user -net nic,model=e1000 -usb -usbdevice tablet -vnc :0 -boot c [673051.444876] Out of memory: Kill process 23037 (qemu-system-x86) score 778 or sacrifice child [673051.444879] Killed process 23037 (qemu-system-x86) total-vm:7418732kB, anon-rss:6018088kB, file-rss:0kB With a RAM amount of 2GiB specified, qemu-kvm will continue to consume RAM until 7GIB physical and 2GiB swap is exhausted.

Core2duo works fine. On a core2duo (e8400/e8500) all cpu options are supported. -- 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
