Hello Anatoly,
I tested this patch series and encountered the same error on both Intel
E810 and Nebulamatrix NICs, as follows:
I used GDB for tracing and debugging, and found that there might be a
slight issue with the code of vfio_group_assign_device function? I won't
insist.
(1) vfio_device_create will alloc a vfio_device dev
(2) vfio_group_setup_device_fd will set dev->fd
(3) DEVICE_FOREACH_ACTIVE(cfg, idev) iterates through each idev->fd in
cfg to check if it is the same as dev->fd, but at this point idev is
actually dev.
So it will report the error "Device 0000:08:00.0 already assigned
to this container".
Hi Dimon,
Thank you for testing it! You're correct, of course. I shall fix it in
v2, along with other planned fixes.
