package: qemu-kvm severity: wishlist tag: patch qemu's default emulated cpu is pentium2. This is often enough not what the user wants and can lead to out of dateness problems like: http://bugs.debian.org/775235
kvm has a "-cpu host" option that automatically emulates the host cpu, which could be better default. Here is an incredibly simple patch to the kvm launcher script that does just that. Including another "-cpu x" option on the command-line overrides the hardcoded "-cpu host" one. Best wishes, Mike
