ovs-vsctl vs. /etc/network/interfaces


Sep 24, 2019

i'm an absolute new in the world of proxmox, so i have a fundamental question about using ovs - yes i know ovs is not specific proxmox, but i will use it in a proxmox virtualization.
in which case i use ovs-vsctl and in wich case the classic interface configuration (/etc/network/interfaces).

the the main question, are there any commands to write the ovs-vsctl commands to the interface config file or thats absolut different thinks ?

so what i wanna do ?

i have two physical interfaces and one of the should be used as vlan trunk and the other with the untagged management.
internal are 3-4 vm which should only present a interface with untagged vlan as access port - so as i seen this can be tap Interfaces - right ?
but what are the recommented way to configure this envirionment ?

thanks a lot

you have to use the interfaces file if you like that your settings stay persistent.
Here is the Doku for it [1].
If you need ovs features where no interface notification exist then you can use
