I am seeking advice in regards to OpenBSD and the vic driver on ESXi server.
I currently lease a physical ESXi server. One of the VMs is an OpenBSD 5.0 system which is configured as a router and serves as a gateway for all the other VMs. This configuration has many advantages for me because it gives me a single point to firewall with pf as well as the ability to upgrade hardware with my provider without changing IP assignments because my /29 and /64 are routed. Recently I have noticed that my speeds are asynchronous. I have tested to various places using various methods and am getting the same results. I am getting 500-700Mbps ingress and 10-50Mbps egress. My ESXi server is in a data center, so I should not be getting asynchronous speeds. In my experience results like these are normally caused by a duplex mismatch or one interface configured for auto-negotiation while the other side is hard set. And here in is my confusion. I canât find any solid documentation as to how to configure the media for a virtual switch. So I assume auto is the way to go. However, I noticed that on my OpenBSD 5.0 router the output of the ifconfig vic0 command simply says: media: Ethernet autoselect It doesnât say what speed or duplex it has negotiated to. Does this matter at all? I noticed that my Enterprise Linux systems the virtual NIC appear to be hard set to 10,000BaseT Full, auto-negotiation disabled (and not available) using the ethtool command. Does anyone have any advice for me? I am paying for a 1000Mbps Internet port and I am only getting a fraction of that on my egress speeds. I opened a ticket with my provider and they confirmed my settings and that my physical switch port is set to auto, as is my physical port on the ESXi server.
