Qemu CLI:
---------
-device pcie-root-port,slot=0,id=rp0
-device nvme-subsys,id=subsys0
-device nvme,id=nvme0,bus=rp0,serial=deadbeef,subsys=subsys0,sriov_max_vfs=1,sriov_vq_flexible=2,sriov_vi_flexible=1

Guest OS:
---------
sudo nvme virt-mgmt /dev/nvme0 -c 0 -r 1 -a 1 -n 0
sudo nvme virt-mgmt /dev/nvme0 -c 0 -r 0 -a 1 -n 0
echo 1 > /sys/bus/pci/devices/0000:01:00.0/reset
sleep 1
echo 1 > /sys/bus/pci/devices/0000:01:00.0/sriov_numvfs
nvme virt-mgmt /dev/nvme0 -c 1 -r 1 -a 8 -n 1
nvme virt-mgmt /dev/nvme0 -c 1 -r 0 -a 8 -n 2
nvme virt-mgmt /dev/nvme0 -c 1 -r 0 -a 9 -n 0
sleep 2
echo 01:00.1 > /sys/bus/pci/drivers/nvme/bind
