Proxmox Open vSwitch API

[hanoon]

For KVM machine creation Proxmox API works however for the creation of the OVS elements such as bridge (ovs-vsctl add-br) - Is there an API way to do that? or any recommendation on how to automate that over an API?

Thanks in advance

the api exist to create ovs config in /etc/network/interfaces

(pvesh create /nodes/<node>/network --iface ... )

with last version of ifupdown2, it's also possible to apply/reload the configuration now. (ifupdown2 will use ovs-vsctl)

(pvesh set /nodes/<node>/network)

Thanks for the quick response - Is there any way to configure without making changes to /etc/network/interfaces file - I would like to use one bridge for all guests in the interface file then the rest is over OVS.

my manual flow is like that:

ovs-vsctl add-br sw
ip link set sw up
ovs-vsctl add-port ${vm_ID}_sw vxlan${vm_ID}_host2 -- set interface vxlan${mv_ID}_host2 type=vxlan options:remote_ip=x.x.x.x options:key=${vm_ID}

That should be saved in conf.db, not in the interfaces file.

Note: I read in another post that ifupdown2 doesn't understand OVS syntax ...

I'm also exploring the set-manager option but not sure what is the best way!

No. proxmox don't manage ovs config, it's using ifupdown or ifupdown2 from /etc/network/interfaces

my manual flow is like that:

ovs-vsctl add-br sw
ip link set sw up
ovs-vsctl add-port ${vm_ID}_sw vxlan${vm_ID}_host2 -- set interface vxlan${mv_ID}_host2 type=vxlan options:remote_ip=x.x.x.x options:key=${vm_ID}

do you want to add port when vm is starting ? (as I'm seeing vmid variable in your example)
if yes, it could be possible to do it in vm hook script

I have create a native ovs plugin for ifupdown2 last month, it's available now, and reload is working now
