1. Check that your VM has the virtio PCI adapters present. You can do this by running lspci from a livecd/installer or grep 1af4 /proc/bus/pci/devices. Look for PCI adapters with vendor ID 1af4 (Red Hat). 2. Check that the virtio kernel modules are loaded by your initramfs. Either check the kernel messages as it boots for virtio-pci or vd* related messages. Or get a debug shell in the initramfs and grep virtio-pci /proc/bus/pci/devices. 3. Did you really mean 'virtoi-blk' in /etc/modules? You can gunzip and cpio extract the initramfs to check that virtio, virtio_pci, virtio_ring, virtio_blk are present.
