There is regression of hotplug removal of virtio-net-pci on q35 introduced long time ago in 3.0.0 with commit: 48564041a73adbbff52834f9edbe3806fceefab7 exec: reintroduce MemoryRegion caching
virtio-net does not destroy some of caching resources upon hot unplug and on further hot plug the device with the same name can not be added. These 2 patches solve the problem.
