After this commit, QEMU domains with PCI hostdevs running with managed=true started to fail to launch with the following error: error : virProcessRunInFork:1170 : internal error: child reported (status=125): unable to open /dev/vfio/1: Device or resource busy One way to avoid this issue is to disable this new feature in qemu.conf, setting remember_owner=0. However, given that this feature is enabled by default and it is breaking domains that were running before it, it is best to revert the change until it is fixed for this scenario as well.
Well, ideally, we want the feature to be turned on by default, just like namespaces for instance. I've temporarily disabled the feature back in the day because we were close to release and it turned out the feature was not ready. But now there is still plenty of time to fix it.
Anyway, I'll investigate. Meanwhile, can you share your <hostdev/> config or even better the full domain definition please?
