I’ve noticed that sometimes when a particular VM/ service is having issues, they all seem to hang. For example, I have a VM hosting my DNS (pihole) and another hosting my media server (jellyfin). If Jellyfin crashes for some reason, my internet in the entire house also goes down because it seems DNS is unable to be reached for a minute or so while the Jellyfin VM recovers.
Is this expected, and is there a way to prevent it?
That’s a good point; My Virtualization server is running on a (fairly beefy) Intel NUC, and it has 2 eth ports on it. One is for management, and the other I plug my VLAN trunk into, which is where all the traffic is going through. I will limit the connection speed of the client that is pulling large video files in hopes the line does not saturate, and long term I’ll try to get a different box where I can separate the VLAN’s onto their own ports instead of gloming them all into one port.
