Good day,

1) When i tried use control panel template and choose Proxmox VE (6) template, after auto-installation is server reachable and interfaces file contains this default DHCP config:

Code: 
auto lo
    iface lo inet loopback

    iface eno3 inet manual

    auto vmbr0
    iface vmbr0 inet dhcp
      bridge-ports eno3
      bridge-stp off
      bridge-fd 0

2) THEN, whe i tried change config from DHCP to STATIC, after (full server and OS) reboot still all work as should - FINE, node is still reachable :

Code: 
auto lo
    iface lo inet loopback

    iface eno3 inet manual

    auto vmbr0
    iface vmbr0 inet static

      address 54.38.192.11/24
      gateway 54.38.192.254
      bridge-ports eno3
      bridge-stp off
      bridge-fd 0

3) BUT: when i reinstall server in IPMI console and install Proxmox 7 from its booted ISO, when i use the same interfaces config, server is unreachable (no ping, no network connection to internet):

Code: 
auto lo
    iface lo inet loopback

    iface eno3 inet manual

    auto vmbr0
    iface vmbr0 inet static

      address 54.38.192.11/24
      gateway 54.38.192.254
      bridge-ports eno3
      bridge-stp off
      bridge-fd 0

4) but then when i run command from IPMI console
service networking restart
network begin work FINE and server is reachable.. after reboot again the same issue - network unreachable

Can anybody or someone from staff @Richard @oguz @Dominic pls explain me WHY is network reachable after reboot with static configuration on Proxmox 6 installed from OVH template,
and with the same static config (/etc/network/interface content) is network not reachable after each reboot on Proxmox 7 installed from ISO through IPMI?
+ when i ran manually networking restart command, then begin network work normally and server/network is reachable (till to another full reboot) :'(

I cant resolve this and do not understand what i should to do or change something in any config on Proxmox 7 to have working it = reachable network with static IP config after each reboot

thank you very much in advance for each help

additional info:

when using OVH template Proxmox 6 + static config

Code: 
auto lo
    iface lo inet loopback

    iface eno3 inet manual

    auto vmbr0
    iface vmbr0 inet static

      address 54.38.192.11/24
      gateway 54.38.192.254
      bridge-ports eno3
      bridge-stp off
      bridge-fd 0

then command ip route
gives:
Code: 
default via 54.38.192.254 dev vmbr0
54.38.192.0/24 dev vmbr0 proto kernel scope link src 54.38.192.11

when have installed Proxmox 7 from ISO and the same interfaces static config + manual networking restart ( service networking restart )
then ip route
gives:

Code: 
default via 54.38.192.254 dev vmbr0 proto kernel onlink
54.38.192.0/24 dev vmbr0 proto kernel scope link src 54.38.192.11

BTW: DHCP config

Code: 
auto lo
    iface lo inet loopback

    iface eno3 inet manual

    auto vmbr0
    iface vmbr0 inet dhcp
      bridge-ports eno3
      bridge-stp off
      bridge-fd 0

also not works on SoYOuStart with Proxmox 7 (network unrechable)
 
Hello,

I have the same issue with a dedicated server from Kimsufi (low-end branch of OVH and SoYouStart).

Since I dont have acces to IPMI, I did investigate via rescue boot image, chrooted in my disks, and read the logs with journalctl -u networking :

Code: 
-- Boot 1d7b66b4b10e4870b9c19a354be86dcf --
Jul 28 10:00:14 pve systemd[1]: Starting Network initialization...

Jul 28 10:00:16 pve systemd[1]: Finished Network initialization.
-- Boot fd6fb88a3e094183baf8a14c81f98d36 --

Jul 28 10:48:48 pve networking[718]: error: vmbr0: bridge port enp1s0 does not exist
Jul 28 10:48:48 pve systemd[1]: Finished Network initialization.

enp1s0 was perfectly fine with ProxMox 6, but no more with ProxMox 7.
 
Hello to all,

my another update: After discussing about my issue on another forums several ppl confirmed the same issue (after installation or upgrade on v7 they got network UNREACHABLE). BTW: On Reddit also many ppl have reported network issues of PVE7

So imo v7 ISO must still contains bugs..
 
and here is (mine) working network log from SYS with PVE6.4 (installed from ISO) with bridged (above mentioned) config, bridge port found and works as should:

-- Logs begin at Tue 2021-07-27 20:23:58 CEST, end at Wed 2021-07-28 13:49:12 CEST. --
Jul 27 20:24:03 pve systemd[1]: Starting Raise network interfaces...
Jul 27 20:24:04 pve ifup[1059]: Waiting for vmbr0 to get ready (MAXWAIT is 2 seconds).
Jul 27 20:24:04 pve systemd[1]: Started Raise network interfaces.
 
It seems people are able to run PVE7 on OVH/SYS/KS with some network adjustments...
Should'nt you add hwaddress in /etc/network/interfaces ?? You have to specifically use the provided MAC

I managed to finally run PVE7 on Kimsufi, by following this tutorial (in french).

In rescue mode, I install PVE7 in a qemu VM with physical disks attached to it.

The hwaddress is mandatory, I had no network access until I added it.
 
Hello I have the same situation: OVH proxmox6.4 template is installing / working without issues
then upgrading following https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0
I looked even at https://pve.proxmox.com/wiki/Upgrade_from_6.x_to_7.0#Linux_Bridge_MAC-Address_Change

read and reinstallated 4 times as I lost network access to box : inbox upgrading : perfect showing proxmox 7 in GUI everything working
tried to get proxmox 7 from upgrading or from installing on debian bullseye box
same result :
after reboot to test setup loosing control and access
access via KVM / IPMI is possible as well as rescue mode
etc/network/interfaces looks like
auto vmbr0
iface vmbr0 inet static
address xx.xx.xx.xx/24
gateway xx.xx.xx.xx
bridge-ports enp1s0
bridge-stp off
bridge-fd 0
hwaddress aa:bb:cc:dd:ee:ff ( added before upgrade)
so network ok till reboot
any suggestions from people here ?
 
Great
after a consulting a networkexpert we got the solution :
/etc/network/interfaces must looks like
auto lo
iface lo inet loopback
iface enp3s0f0 inet manual
iface enp3s0f1 inet manual
auto eth0
iface eth0 inet static
address xx.xx.xx.xx
netmask xx.xx.xx.xx
gateway xx.xx.xx.xx
bridge-ports enp3s0f0
bridge-stp off
bridge-fd 0
dns-nameservers xx.xx.xx.xx
.....
