[SOLVED] Brand new install - VMs cannot connect to network. No traffic.

[denormalize]

Firstly, please don't berate me. I am new to Proxmox.

I recently purchased a dedicated server and loaded Proxmox 8 on to it. Loaded up Ubuntu Server 24.04.1 and all was going well until I realized I had no connection at all. Cannot even launch the Ubuntu server.

I have only 2 entries for "pvehost" --> System --> Network. They are:
enp5s0 (Network Device) - No IPV4 or Gateway or Port
vmbr0 (Linux Bridge) - Active (Yes) Autostart (Yes), Ports/Slaves are enp5s0, CIDR/IPV4 is my correct main dedicated IP for my server and the gateway is also correct.

Isn't there supposed to be more entries there? For eth etc?

I've played with configuration to make sure it wasn't a virtual network card issue, rebooted, poked around in the console of the host; nothing.

lspci -nnk | grep -A2 Ethernet

shows the following (just so we know I do have a functioning Ethernet port):

05:00.0 Ethernet controller [0200]: Intel Corporation 82599 10 Gigabit Network Connection [8086:1557] (rev 01)
        Subsystem: Intel Corporation Ethernet OCP Server Adapter X520-1 [8086:0001]
        Kernel driver in use: ixgbe
        Kernel modules: ixgbe

Any help would be greatly appreciated. I reached out to my host to see if they had any suggestions. They talked about DHCP but I don't think that is applicable here as I can't even boot the server, and the install .iso also was offline.

Hi,

usually no, that is just fine.

Would you like to share the configuration of the Ubuntu Server VM (qm config <vmid>and the errors you get, when trying to launch it?
And for the network: how does the VM get it's IP address, if there is no DHCP server available, IP address has to be assigned manually.

Hey man,

So, I ended up fixing it. I set up a local DHCP type thing (https://pve.proxmox.com/wiki/Setup_Simple_Zone_With_SNAT_and_DHCP) and created a bridge like outlined in that documentation, which allowed me to connect flawlessly. Now, I am tackling the issue of reusing gateway addresses to assign static IPs w/ Linux Bridges, but that's another thread for another day...

Thank you for your willingness to help! <3
