Recently had a issue where my network connection would just die on a VM I was running every couple hours. I spent days trying to troubleshoot that and never found an answer and eventually resigned myself to having to restart the whole thing every day or so. A while back I realized that it had just.... stopped doing that. No, idea what changed other than some updates that had been done, but I never found any reports of that issue anywhere that would indicate it was on someone's radar to fix.
