I recently had to move my ProxMox instance to a new computer as the fan in my HP Prodesk was going out causing the CPU to overheat and shutdown. I moved the Hard Drive from my Prodesk into an Intel Nuc with the same amount of memory and a newer CPU. It boots up just fine but the Network is always down on reboot. When running "IP A" I see the interface has a new name and I went through the process of updating the /etc/network/interfaces to reflect that in both of the locations the old interface was being referenced. I can manually bring the interface up after rebooting but every time I reboot it goes back down. I tried running both ifdown and ifup commands on that interface and I don't get any error for ifdown but ifup doesn't recognize the interface name.
