Another finding is that i can change the mtu less then 1500 my system is dell precision 490. i have other system on squeeze with no issue at all. but they are on proxmox.
i have tested that i can set any value less then or equals to 1500 mtu but when i even try 1501 it says SIOCSIFMTU: Invalid argument i have same system working on proxmox. deployed on debian squeeze and i can go up to 9000 with no problem. this problem is in non proxmox system having debian wheezy with libvirt. Please guide.
