Xen DomU's do not have network access on bonded NICs

This document (3180769) is provided subject to the disclaimer at the end of this document.


SUSE Linux Enterprise Server 10 Service Pack 1


When the physical NICs have been bonded the following may exist:
  • Xen Dom0 looses network access when in Xen kernel, but network access works correctly in non-Xen kernel
  • Xen DomU's do not have network access, but Dom0 does.


For SLES 10 SP1 and earlier, bonding is not supported by SuSE Development while running in the Xen kernel; there a variety of reasons for this, but most it has to do with the default handling of creating the network devices. Further, the default Xen Networking script, network-bridge, does not handle multiple NICS very well.
In the future release of SLES 10 SP2 the "network-bridge" script will support VLANs and bonding.
