Have you compiled the Virtio Block device into your kernel ? You need  
it in the kernel, not as as module.

In 'make menuconfig' you can find it under "Device Drivers" -> "Block  
Devices" -> "Virtio Block Device". It's experimental so you need that  
enabled as well.

Hope that helps - it helped me when I had that exact same error :-)
