This one does the same, just via a different syntax (the default block type for the 'virt' board is IF_VIRTIO). I'm not sure exactly how you would create an SD card for the 'virt' board (probably by using the sdhci-pci device which is a PCI sd controller) but I think it would be better to fix the guest to use the virtio devices and not insist on looking for an SD card -- the performance from an emulated SD card will be a lot worse. thanks -- PMM
