Hi,
we use LXD containers on our CI-build nodes. For each build a container is
created and deleted afterwards. So, container creation and deletion happens
quite often.
Here is the problem: After some time, many virtual ethernet interfaces (veth*)
accumulate, they look like this:
vethY59JK1 Link encap:Ethernet HWaddr fe:12:cc:54:20:70
inet6 addr: fe80::fc12:ccff:fe54:2070/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:60 errors:0 dropped:0 overruns:0 frame:0
TX packets:14095 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6735 (6.7 KB) TX bytes:2417738 (2.4 MB)
...
vethYCP720 Link encap:Ethernet HWaddr fe:6c:d0:78:b0:63
inet6 addr: fe80::fc6c:d0ff:fe78:b063/64 Scope:Link
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:61 errors:0 dropped:0 overruns:0 frame:0
TX packets:14075 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6653 (6.6 KB) TX bytes:2414750 (2.4 MB)
These interfaces are not connected to any running container and cannot be
removed. It seems to me that they are somehow leftovers from previous
containers which don't exist anymore.
Could this be a bug in LXD?
We use version LXD version 3.9.
Thanks!
Best,
Holger
