  • Applies to:
  • Virtuozzo
  • Virtuozzo containers for Linux
  • Virtuozzo hypervisor

Symptoms

  1. Sporadic network outage is experienced inside containers from time to time.
  2. The node has several physical network interfaces teamed into a bond with load balancing mode.
  3. Containers are configured in bridged mode.

Cause

The node is configured with one of the load-balancing bonding modes (balance-rr, balance-xor, 802.3ad or balance-alb), which requires additional configuration or needs support of LACP on the switch side.

Resolution

See the article Which bonding modes are supported on PVC/PCS/PSBM servers? for the details on the proper bonding configuration.
