qemu does not have a PCI endpoint capable controller device and you cannot link
2 VMs to communicate over PCIe (one VM as host the other as endpoint). So unless
you get a PCIe-endpoint capable board, you cannot run this driver easily.

We can add a blktest case for sending an unsupported command though. That is
easy to do. But FYI, right now, running blktest/nvme group against a pci-epf
device, we get a hang... Shin'ichiro is looking into that.
