Subject: [Qemu-devel] [Bug 1633508] [NEW] libvirt cannot hot insert interfaces to qemu
Date: Fri, 14 Oct 2016 14:36:33 -0000 [thread overview]
Message-ID: <20161014143633.7783.6982.malonedeb@gac.canonical.com> (raw)
Public bug reported:
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
