[Qemu-devel] device_del

    Should device_del work with a vfio device and qemu-2.3? I
configure a pass-through device in a q35 machine:

-device vfio-pci,host=84:00.0,bus=root.1,addr=00.0,rombar=0,id=SAS.2

   And try to delete the device through the monitor:

virsh qemu-monitor-command scos --hmp --cmd 'device_del SAS.2'

    There are not complaints but the device did not go away:

        bus: root.1
          type PCIE
          dev: vfio-pci, id "SAS.2"
            host = "0000:84:00.0"
            x-intx-mmap-timeout-ms = 1100 (0x44c)
            x-vga = false
            x-req = true
            bootindex = -1 (0xffffffffffffffff)
            x-mmap = true
            addr = 00.0
            romfile = ""
            rombar = 0 (0x0)
            multifunction = false
            command_serr_enable = true
            class SAS controller, addr 04:00.0, pci id 1000:0097 (sub 1028:1fbd)
            bar 0: i/o at 0x5000 [0x50ff]
            bar 1: mem at 0xfe640000 [0xfe64ffff]
            bar 3: mem at 0xfe600000 [0xfe63ffff]

    Or is this a job for object_del?

    Thanks in advance....
