Proxmox - Troubleshooting - No internet on VM
Installed Ubuntu Server 20.04, but no Internet.
During the install of Ubuntu it gets to networking, where it reports no networking found.
- Tried with DHCP and with Static IP.
- The VM does get created but no networking on it.
Can ping the Proxmox host, but nothing else.
Check PCI devices
lspci | grep Ethernet
returns:
03:00.0 Ethernet controller: Intel Corporation Device 15f3 (rev 02)
Does the NIC support bridge mode with the default driver
On the Proxmox host:
brctl show
returns:
bridge name bridge id STP enabled interfaces vmbr0 8000.a8a1592fb8a6 no enp3s0
NOTE: A newer driver might need to be compiled to get bridge mode supported.
Check udev
udevadm info /sys/class/net/vmbr0
returns:
