The hard disk sm2262 controller cannot passthrough

[bigbug]

I encountered an error when I tried to passthrough the HP SSD Ex920, which caused the virtual machine to fail to start normally, and the prompt is as follows

swtpm_setup: Not overwriting existing state file.
kvm: -device vfio-pci,host=0000:02:00.0,id=hostpci2,bus=pci.0,addr=0x1b: vfio 0000:02:00.0: failed to add PCI capability 0x11[0x50]@0xb0: table & pba overlap, or they don't fit in BARs, or don't align
stopping swtpm instance (pid 109194) due to QEMU startup error
TASK ERROR: start failed: QEMU exited with code 1

Hi, i am not sure if you have fixed the issue by now, but i ran into the same issue with an SM2263 controller device and the solution you posted worked. I belive you need to make sure the ID of hotpci on the args you are adding to the vm.conf file has to match the ID of your device so in your case the line should look like this:

args: -set device.hostpci2.x-msix-relocation=bar2
