Hi all,
i have spent a few days on this particular error. I would like to share the solution here.
A few weeks back i converted my BSD systems to run virtio. At first i thought it had no problems but last week i checked the proxmox server and came accross the error below.
After searching for the problem i found on launchpad a guy which converted his BSD systems back to using e1000 network card and the error disappeared. So i did the same and my Warnings are gone.
