[Zhang, Xiong Y] yes, both host and guest use the same kernel/driver.

[Zhang, Xiong Y] it is close to work.

[Zhang, Xiong Y] Please check whether intel_iommu is enabled on host or not. If it isn't , please add intel_iommu=on to host grub.
is the dmesg from host or guest ?
If it is guest, this message shouldn't appear according to your qemu boot parameter.

Please paste qemu output.
