+libvirt cannot hot insert interfaces to qemu
+
+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
+
+
+This seems to be an old bug, but is still present.  Other relevant information:
+$ qemu-system-x86_64 --version
+QEMU emulator version 2.5.0 (Debian 1:2.5+dfsg-5ubuntu10.5), Copyright (c) 2003-2008 Fabrice Bellard
+$ virsh -v
+1.3.1
+
+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?
+
+That seems to be the Libvirt of Ubuntu in Xenial.
+
+In the past similar issues were uncommon configs or changed behavior on updates that triggered apparmor or SELinux protection.

+
+It could as well be some variant of bug 1677398.
+
+If you are still affected by this, could you check:
+1. if it also happens on newer libvirt versions e.g. do a trial run in the most recent Ubuntu
+2. if it does could you check dmesg in your setup for related apparmor denials?
