I've been running proxmox on a DL380G7 for a couple of years. I've slowly been migrating machines from an old ESXI server. Yesterday, while troubleshooting an unrelated network issue, I noticed that I was significantly behind on updates so I upgraded using the option in the web gui. Upon a reboot, I had zero connectivity into the box either on vmbr0 (management, single VLAN access port) or vmbr1 (trunked VM bridge).
After grabbing a crash cart of sorts, I began to poke around. I tried rebooting, using systemctl to restart the networking service, and many other options that my internet searching turned up.
Eventually, I was able to get vmbr1 up by using the 'ip link set vmbr1 up' command. After a short while, I began to see VM's with network connectivity. Using the qm command to bring up additional VM's I was able to restore most functionality, But I still had/have no management interface. Performing the same ip link command on vmbr0 appeared to bring it up, but it did not have an IP, despite what was configured in /etc/network/interfaces.
i have searched and read so many different posts, but have not found an answer. At this point, I feel like my only recourse is to re-install proxmox and import the existing VM's, but I still feel that I should be able to get the management interface back up, if for nothing else than to help ease operation while I migrate a handful of ESXI VM's over and then wipe ESXI and rebuilt it into a new proxmox server.
For now, if I need to access management functions, I have to RDP into a Win10 box and then use HP iLO to access the console, or go sit in front of the machine. Neither option is ideal
Happy to provide any additional information.
