My box is running with this KVM enabled inside kernel. I also built qemu-kvm-0.12.2 using above kernel headers etc. I enabled virtualization in BIOS. I didn't try to install any guest from CD etc. I made a hard disk image, installed grub on it, copied kernel, initrd onto it.

So right now "-m 128", which is default, works. Why is that? I have 4G RAM in my setup and my native linux is using less than 1G.
