I have a small personal Hyper-V server with 12 guests all sharing one virtual switch. I was doing some tests to see why some pings were randomly high and I wrote a script to log/email high ping times. It runs on one of the guests and pings IPs, such as the router and other devices on the LAN.
Out of curiosity, I had this guest ping another guest on the same server. In theory, I thought that this would go across the virtual switch without even leaving the physical server, but I've noticed randomly high ping times.
So, Guest 1 is pinging Guest 2 on the same Hyper-V server, same virtual switch, and some ping times are randomly high.
1. Between these two, would a packet even venture out into the physical network, or stay entirely on the virtual switch?
2. What would explain why some pings across the same virtual network are high?
3. Could this spike be due to some sort of software latency?
I don't really have a problem, but am more curious as to why this may be. It is usually 1 ping out of about 100 that is randomly spiked. TIA.
