Open vSwitch (OVS)

Proxmox VE

Install Open vSwitch

Update the package index and then install the Open vSwitch and ifupdown2 packages by executing:

apt update
apt install ifupdown2
apt install openvswitch-switch

NOTE: In the version of Proxmox we are using, the package ifupdown2 is installed. Why is that important? Originally in Debian you have to reboot the whole server in order to apply changes to network settings. The ifupdown2 package allows us to apply changes without the reboot.

Before edit /etc/network/interfaces, please backup this file.

cp /etc/network/interfaces /etc/network/interfaces.backup

Editing:

vi /etc/network/interfaces
