The reason I ask this question is because that I don't have any virtio-pci and virtio-blk modules loaded in my guest but still I could access the virtual block device.

Can somebody explain me the roles of virtio-pci and virtio-blk modules on the guest in accessing the virtual block device. I am unable to understand the design.
