A question about ovs-vlan-test

Asked by Havent

What is ovs-vlan-test(ovs-test)'s purpose? What can it prove?
The document says that there must be a host proved no problem with vlan as server, to test a host whether it has vlan problem as client. But how do I find this no problem host? Do both of ovs-vlan-test server and client can run on one single host to prove this host doesnot have vlan problem?

Another question, if there are two VMs in the same VLAN and they're on the same physical host, when I ping from VM1 to VM2, and I can be connected, does the ICMP packet go through the physical ethernet interface card or just go within the openvswitch not through the physical ethernet interface card?

regarding ovs-vlan-test, that utility is not related to openstack, so your best bet is to look at the OVS docs or email the OVS list.

for your second question, communication between two VMs on the same server using the same VLAN will be handled entirely within OVS, without the packet reaching the NIC.
