Hi, on libvirt 3.10 I see a set of qemu processes used for capability probing [1] (in my case 8x x86_64 and 3xi386 which seems a lot, but ok). But when stopping the service those still stay around [2]. That is correct for guests that were started by libvirt as their lifecycle isn't tied to the libvirtd service. But those probes are IMHO tied to the service. At first this might seem non-relevant, but e.g. when users want to uninstall they might think on stopping their guests, but I'd assume no one will clean up the capability probes before the hard removal. But then on the removal scripts will run into issues e.g. failing to remove users as they are still in use by those qemu processes. Right now Distro's have to be aware to clean those up at least at times where packaging would expect them to be gone, but I wanted to ask if there would be a consensus that it would be "correct" to stop the processes on a libvirtd stop?

I discussed this on IRC last Friday, but other than Michael confirming the current state there was no further traction on the discussion yet. -- Christian Ehrhardt Software Engineer, Ubuntu Server Canonical Ltd -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
