Issue
- Which bonding modes work when used with a bridge that virtual machine guests or containers connect to?
- When using certain network interface bonding modes on RHEL or RHV virtualisation hypervisors, with the bonded interface in a bridge that virtual guests have their network interfaces bridged into, the guests will suffer network connectivity issues such as packet loss, poor performance or no connectivity altogether.
- When using containers with certain networking modes and bonding modes where the container uses its own MAC address and does not NAT on the container host, the same loss of connectivity can apply.
Environment
- Red Hat Enterprise Linux (any version)
- Red Hat Enterprise Virtualization Hypervisor (RHEV-H) (any version)
- KVM-based or Xen-based virtual machine hypervisor
- Multiple network interfaces bonded on hypervisor
- Bonded interface in bridge
- Virtual guest network interfaces in the same bridge
- Containers (for example, LXC, Docker, Kubernetes, OpenStack, OpenShift, CoreOS, and others)
- Container configuration where the container uses its own MAC address, such as Docker's MACVLAN mode
- OpenShift Virtualization
