I have a Proxmox cluster implemented and configured on my environment with PVE 5.4 version. All virtual machines are working about 1 months or 2 moths and then the network inside the virtual machines becomes showing yellow triangle on the network icon (then unable to ping from another hosts). I need to disable and re-enable network connection and then working ok. I am using virto driver to provide link for those vms. can anyone know what is the problem? how to fix it?

Thanks,

Sor
 
Please upgrade to the latest virtIO drivers inside the VM (I assume Windows). And best also upgrade your installation to the latest packages.
 
Thank you Alwin, I will try to upgrade virtIO drivers. I can't do upgrade Proxmox OS yet. I never try it as I have many production servers are running on this. It is clustering. Any upgrade guideline to process upgrade Proxmox?
