While testing >=v5.0.0 on Fedora 32 I've stumbled across the following change in QEMU:

https://github.com/qemu/qemu/commit/cce8944cc9efab47d4bf29cfffb3470371c3541b

The change suggests that previously parallel requests to detach a PCIe device (such as virtio-blk) from QEMU would result in the original request being cancelled. We are hitting the above check and error with v5.0.0 in OpenStack CI that made me wonder if we are hitting the original issue in this bug where QEMU is < v5.0.0?
