Installation of Proxmox was successful. But vmbr0 is showing down. tried manually making the port up but still not coming up. Installation was done on one of the blade HPE BL 460c server, The blade is enclosed in HPE C700 Chassis. Any idea why this might be like this.

Hi @Abinsha , welcome to the forum.

It would be extremely helpful if you can provide any illustration to go along with your report. Basic network troubleshooting in Linux starts with :
- review /etc/network/interfaces
- review output of "ip a"
- review system log: journalctl -b0

The main thing to keep in mind that the PVE, as a product, uses Debian Linux as the base OS. So simple network troubleshooting is the same as for almost any Linux system.

Good luck
