Hello
I'm running proxmox 3.4-6/102d4547 for about a year and so far I'm pretty satisfied.

A few days ago I created a new virtual machine, to be used as an Ubuntu 16.04 x64 LTSP server.
The hardest part about this is the pci passthrough. Since the ltsp server usually uses 2 NIC's, one for the internet and the other one for the thin client network, I added a second Realtek gigabit pci-e lan card and followed this wiki: https://pve.proxmox.com/wiki/Pci_passthrough

I edited grub and updated grub.The "dmesg | grep -e DMAR -e IOMMU" command showed some output. I added the 4 required modules, edited the VM's conf file and added "machine: q35" and "hostpci0: 03:00.0,pcie=1".

After rebooting everything was working great. I saw the Realtek lan card inside Ubuntu and I was able to make the ltsp server setup with the thin clients.

It was a few hours after that, when I decided to check the console of proxmox, when I saw this:

It's constantly moving, that's why there is flickering at the top and the bottom.

What seems to be the problem? Everything is working fine except for this error. I guess it's constantly looping and loading the cpu and it's just bugging me out.
