Beta VXLAN Issue

[Keyninja]

Hi Guys,

So, I'm attempting to roll out the new GUI SDN at my home Prox lab. Currently, when I create a VXLAN Zone "mynet" and a VNet "vnet1", and attempt to apply the config, I get an error on all nodes, picture attached.

I checked in Syslog and all I can really see is an entry of "pvestatd[2577]: local sdn network configuration is too old, please reload", and some ovsctl commands clearing LACP and a few other items. Nothing really seems to point to where the error is.

Does anyone know of some more verbose troubleshooting for SDN? Also, if there's any better docu around for the EVPN zone, I'd love to try that out too.

Thanks,

can you send content of /etc/pve/sdn/vnets.cfg && /etc/pve/sdn/zones.cfg , + /etc/network/interfaces config file ?


do you /etc/network/interfaces have a line
"source /etc/network/interfaces.d/*" ?

because sdn generate an /etc/network/interfaces.d/sdn config, and it must need to be include in main config.


about documentation, I'm currently working on new sdn version with a lot of new features, including an improved doc, but it's not yet commited yet

Sorry my interfaces is a bit busy, I was playing with using OpenvSwitch bridges for my 10G Ceph traffic.

Found it!

By echoing that line onto my interfaces file:

echo "source /etc/network/interfaces.d/*" >> /etc/network/interfaces

And reloading network from the main SDN tab, that made them available! Thanks for the help! I'm surprised it doesn't add that line by default though when it applies the SDN configuration.

ok, just add ""source /etc/network/interfaces.d/*" at the end of /etc/network/interfaces , and re-apply sdn config, it should works.

This is in documentation, but not at the begin. (you are not the first to ask for this). I have rewrote the documentation to not forget it.

yes, currently I don't change /etc/network/interfaces. I'll try to auto-add it for next version

One other thing too, is clicking on the "mynet" zone under each host tab freezes the Web UI. I'll be testing the VXLANs today and hopefully EVPN in the future.

yes, it's a known bug. I have already fixed it for next release. (currently it's not blocking, it's only for monitoring state of a special vnet in a zone and add permissions)

Coming version have also support for evpn with ebgp, if you use ebgp in your environnement. (currently it's only ibgp with full mesh between proxmox nodes). but evpn is already working.
