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?

If the VM crashing is because of high CPU usage on all cores, high IO delay on the storage, or an out of memory situation on the host, that would cause all of the other VMs to struggle as well.
