KVM/Qemu Crashes

I'm trying to get a KVM to work but right after the boot menu it crashes, I've tried both CentOS and Arch, so I know it's not specific to the image. The images also work because I have used them in VirtualBox just fine. My processor supports hardware virtualization (it's a Core i7 Ivybridge) and I have the modules loaded.

I'm using Linux-CK from GraySky's repository and that also supports kvm and virtio

 [bran@ra ~]$ zgrep CONFIG_KVM /proc/config.gz

CONFIG_VIRTIO_MMIO_CMDLINE_DEVICES=y

Yet when I try to boot the CentOS image via sudo qemu-system-x86_64 -cdrom centos.iso -boot order=d MyMachines/Linux/Linux.img it just gives me this error failed to access perctr msr(msr c0010004 is 0) and the rest of the screen is white (probably a hung splash screen?) and it just stays there. Arch will give me that same error but then the kernel will crash.

What's the problem here?
