我买了一个4端口网络适配器PCIe卡（Intel E1G44HT 10/100/1000Mbps PCI-Express 2.0服务器适配器I340-T4）
我正在尝试将其安装在我的 hpZ600 工作站中，并将其传递到我的客户虚拟机
我正在运行 Artix Linux，但主要遵循 Arch Linux 的指示。
问题是我无法将该卡传递给我的 VM。
以下是我目前所做的：
首先我更新我的 default/grub
$ sudo -E nvim /etc/default/grub
...
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet intel_iommu=on iommu=pt vfio-pci.ids=8086:150e"
...
然后我重新制作我的 grub 配置
sudo grub-mkconfig -o /boot/grub/grub.cfg
我重新启动并确保一切正常
sudo reboot -h now
我检查 dmesg 的输出
sudo dmesg | grep -i -e DMAR -e IOMMU

我验证了我的 vfio 组
ls /dev/vfio
16 17 18 19 vfio
然后我启动我的虚拟机
qemu-system-x86_y4 \
-m 8G \
-enable-kvm \
-cpu host \
-smp 2 \
-net none \
-device vfio-pci,host=03:00.0,id=net0 \

-drive if=pflash,format=raw,readonly=on,file=/usr/share/edk2-ovmf/x64/OVMF_CODE.fd \
-drive if=pflash,format=raw,file=uefi_vars.fd
导致以下错误：

我不知道下一步该做什么。有什么想法吗？
