[SOLVED] VM could not acquire IP address

[SpookyAction]

Installed Proxmox using all default options + running update. Version 8.04

First time using Proxmox. Please be lenient with the clumsiness of the report. Would appreciate guidance how to provide better feedback and diagnostic info.

Created a test VM using Alpine Linux 3.18.4, https://dl-cdn.alpinelinux.org/alpine/v3.18/releases/x86_64/alpine-virt-3.18.4-x86_64.iso. All default options. In particular, network device = bridge vmbr0, model = VirtIO, VLAN tag = no VLAN

The VM boots successfully. But doesn't have IP address and could not connect to the Internet. Connecting to the console of the VM. `ip address` doesn't show any local IP address. `ip route` retuns empty string

On the PVE node, System/Network. Shows Linux Bridge vmbr0 as IP4/CIDR = 192.168.1.80/24, Gateway = 192.168.1.250. Which is the address space of the home network. The home router is indeed 192.168.1.250.

Network is working on the Proxmox node itself. I could SSH into the node and run apt update/upgrade.

Thanks very much in advance for any help.

Proxmox does not give out IP addresses to VMs. You'll need to setup a (virtual) DHCP server for that or configure the IP address manually inside your VM. Maybe Alpine Linux has a guide on how to do that?

i setup a dhcpd local on an isolated vmbr, ipv4 with lan 10.10.x.0/24.
this run on a LXC with debian 12 and isc-dhcp-server is the dhcpd.

The setup is simple and you find many help pages.

Hi,

Please ignore the question. Actually, the VM could acquire a dynamic IP addr from the home router via the vmbr0 bridge.

The cause of the error had nothing to do with Proxmox. When booting the Alpine Linux VM. I had forgotten to complete the OS setup by running `setup-alpine`. After completing this step, the VM reboots and had network working OK.
