Proxmox VM's hanging when one has issues (self.selfhosted)

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?

I typically prefer VM's just because I can change the kernel as I please (containers such as LXC will use the host kernel). I know it's overkill, but I have the storage/ memory to spare. Typically I'm at about 80% (memory) utilization under full load.
