OVS should be able to do what you want. You set up your physical NIC as a trunk port and your VM's port as an implicitly tagged VLAN port. (But I did not read the PDF that you passed along.) The userspace-only Open vSwitch might have problems with VLAN tagging that the kernel implementation does not. In particular I believe that the kernel prevents the userspace OVS from using the full MTU size. At any rate it has certainly not been tested as much as the kernel implementation. You say that the Open vSwitch kernel module won't compile on 2.6.32.8, but it should. What errors did you see? _______________________________________________ discuss mailing list [email protected] http://openvswitch.org/mailman/listinfo/discuss_openvswitch.org
