Do you have the full command line? Also, why/where is device_add failing? Can you add a puts(driver); before the unrefs? I tried something very similar to the above, with commands like netdev_add bridge,helper=/usr/libexec/qemu-bridge-helper,br=virbr0,id=dev1f0 device_add virtio-net-pci,netdev=dev1f0,id=nic1f0,addr=0x1f.0,multifunction=on and it hotplugged all 224 devices this way without any failure. Did you try running with MALLOC_PERTURB_=42
