Hello virtualizations, Please can anyone tell me what happens in the following scenarios: 1. freebsd-11 server, 5x freebsd-11 guests The server has 32GB ram installed. it's an i7 so 8 cores. There's 64GB swap. Each guest that bhyve loads is with m 8192M, so ram is overcommitted by 6GB. What happens to the guests and the server? Do either (or both) crash? Or is there something in bhyve that will make memory allocated on a best-effort basis? 2. In the following context, the server is the same but this time all five guests have -c 4 per guest, so bhyve is asking 12 more cores than that existing in hardware. Does the guest fail to load, do either guest or server crash? thanks, -- J.
