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,
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-
$ virsh -v
1.3.1
affects: | qemu → libvirt (Ubuntu) |
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?
