Could not unbind VFIO Error on Drop #107
Description
Hi,
When working with vfio, I store Arc<VfioContainer> and VfioDevice. When I drop the structures at the end of my application, I get the following error: ERROR: [vfio_ioctls::vfio_device]: Could not unbind VFIO group: 15.
This error message prevents me from binding the default driver back to the PCI device: "Device or resource busy."
Do you have any idea what could be going wrong?
