Hi Andre Arapov,

Thank you for the guide. I am attempting to replicate your results on my 14,3 Macbook Pro from a fresh install of Qubes4.1(built in mid May). I started by removing the wireless card 03:00.0 from sys-net in Qubes settings → Devices tab so that starting sys-net will not freeze the system. I am encountering an error when running “sudo xl pci-attach sys-net '03:00.0,permissive=1'” where Domain 1 is sys-net and the only other running domain is dom0.

libxl: error: libxl_pci.c:1575:libxl__device_pci_add: Domain 1:PCI device 0000:03:00.0 already assigned to a different guest?

libxl: error: libxl_pci.c:1735:device_pci_add_done: Domain 1:libxl__device_pci_add  failed for PCI device 0:3:0.0 (rc -1)

libxl: error: libxl_device.c:1414:device_addrm_aocomplete: unable to add device

I get this error despite "xl pci-assignable-list" showing 0003:00.0. I am not sure how it could already be assigned to a different guest because there are no others running. Am I doing something wrong? I even tried unbinding the pcieport by running “ echo 0000:00:1c.0 | sudo tee /sys/bus/pci/drivers/pcieport/unbind” before I ran “sudo xl pci-attach sys-net '03:00.0,permissive=1'”?

Any input would be appreciated.

Thank you in advance,

LinuxTom
