[Bug 1633508] Re: libvirt cannot hot insert interfaces to qemu

[Thomas Huth]

This looks like a libvirt bug at a first glance. Have you tried to
report it to the libvirt project? (See https://libvirt.org/bugs.html )
... also, can you re-create the bug with the very latest upstream
version of libvirt and qemu, or does it only occur with an (older?)
version of Ubuntu?

Title:
  libvirt cannot hot insert interfaces to qemu

Status in QEMU:
  Incomplete

Bug description:
  When attempting to hot insert an interface using Ubuntu 16.04.1, I get the 
following
  $ virsh attach-interface --domain gluster1 --type direct \
  >         --source test0 --model virtio \
  >         --mac 2a:b6:b0:dc:c7:c4 --config --live
  error: Failed to attach interface
  error: internal error: unable to execute QEMU command 'getfd': No file 
descriptor supplied via SCM_RIGHTS

  test0 exists:
  $ ip link show test0
  35: test0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast 
state DOWN mode DEFAULT group default qlen 1000
      link/ether aa:8c:65:2e:79:61 brd ff:ff:ff:ff:ff:ff

  Just in case I did it wrong with direct, I did network
  $ virsh net-list
   Name                 State      Autostart     Persistent
  ----------------------------------------------------------
   default              active     yes           yes
   mgmtnet0             active     yes           yes

  $ virsh attach-interface --domain gluster1 --type network \
  >         --source default --model virtio \
  >         --mac 2a:b6:b0:dc:c7:c4 --config --live
  error: Failed to attach interface
  error: internal error: unable to execute QEMU command 'getfd': No file 
descriptor supplied via SCM_RIGHTS
