PCI passthrough issue

[kifeo]

Hi !

I have a usb device that I would like to attach to a VM.
It was working previously, but now the pci passthrough does not work with the message :
"Parameter verification failed. (400)

usb1: hotplug problem - VM 102 qmp command 'device_add' failed - usb port 2 (bus xhci.0) not found (in use?)"

And in case I use the USB port attachment I have this message :
"checksum missmatch (file change by other user?) (500)"

Do you have an idea on how to resolve this ?

Thanks !

Hi,

can you post the version (pveversion -v), the config (qm config ID) and the pending config (qm pending ID) ?

Thanks @dcsapak , here is in attachment the requested outputs.
note that the current usb device is spice, as I cannot set the correct one

mhmm what happens when you shutdown the vm and then add it, does that work?

i can only see a single usb port (spice) that is configured/pending

maybe that spice port blocks the addition?

also can you try to set it on the cli?

qm set ID --usb0 <your usb device port/vendor/id>

(see man qm.conf for a detailed explanation of the usbX config format)

Thanks for the help @dcsapak , I thought I tried it when it was shut down, but apparently not.

It works now.
