I'm using two virtual functions per VM, mainly because I need loopback (the LLE(PFVMTXSW[n]) register is not allowing loopback on a VF by default). After adding a second VF to the VM's I often see issues where no traffic is passing between the VF's. Each VM has 4 legs: 1. mgmnt (vmxnet over the onboard 1 GB)- ssh connections 2. data mgmnt (vmxnet over the physical function) - "Trusted interface" to ping DPDK apps/KNI 3 + 4) VF bound to igbuio - for the application. The issue I see, is that some VF cannot communicate with other VF's either same nic or a different Nic. For example two "data mgmnt" vmxnet3 interfaces (not bound to DPDK) cannot see each other. The only thing that seem to solve it is a VM shutdown (a reboot of a VM will not help). Has anyone seen something like this? any suggestions how to debug analyse what I'm seeing.
