This is because the virt board doesn't have an SD controller.

You could try plugging in the PCI SD controller with '-device pc-sdhci'
and then plugging the emulated SD card into that. But if you can
I would really recommend not trying to use SD card. Use some other
kind of block device -- surely OPTEE has support for other kinds
of disk ?
