Proxmox ve host maschine changes mac adress after restarting networking

[Andrey Prokopenko]

Hello, sorry for my not good English.
my host maschine changes mac adress on vmbr0 interface after restating /etc/init.d/networking
Proxmox Ve installed on other maschine and Hard disk with system was replaced on other maschine in same subnet.
How to resolve problem with networking?

Hi,
if I understand you right, you migrate your pve-installation to an host with different NICs?
Then the numbering of the eth-devices changed. See with following command and change /etc/udev/rules.d/70-persistent-net.rules to your needs (and reboot after that)

dmesg | grep eth
cat /etc/udev/rules.d/70-persistent-net.rules
cat /etc/network/interfaces

Why do you restart networking? There is no guarantee that a bridge keeps the same MAC (unless you hardcode a MAC with hwaddress - see 'man interfaces')
