The sriov agent was polling devices via 'sudo ip link show', and this resulted in a severe memory leak. The usage of 'sudo' uses the host 'dbus-daemon', and somewhere the host does not clean up login sessions. Symptoms: - gradual run out of memory until system unstable, host spontaneous reboot due to delay or OOM - huge growth of kernel slab - thousands of /sys/fs/cgroup/systemd/user.slice/user-0.slice session-x*.scope files with empty 'tasks', i.e., sessions that should have deleted - huge latency seen with ssh and various systemd commands The problem is mitigated by disabling 'sudo' for sriov agent, using a helm override that configures [agent]/root_helper='' . Testing: - Verified that we could launch a VM with SR-IOV interface; VFs were able to set MAC and VLAN attributes.
