XCP-ng 8.3 updates announcements and testing

marcoi

went well with test systems. going to do prod soon.

Ran into some issues with sdncontroller.py (XCP-ng 8.3 and xcp-ng-xapi-plugins-1.16.0-1) when creating traffic rules on VLAN VIFs (and networks) in XOA — same error on both Premium and Community. The problem turned out to be a line feed sent by XOA.

On line 236 of sdncontroller.py, I added a fix that solved the problem, and it now works perfectly managing traffic rules in XO on VLAN networks:

def update_args_from_ovs(args):
    # FIX: strip line feed (\n \X0a) sent by Xen Orchestra
    args["bridge"] = str(args["bridge"]).strip()
    # get parent...

I had another problem when adding rules on networks that weren't connected on all hosts, because those hosts didn't have VMs running on that network (default). Manually connecting them worked fine.

I think it's more of an XO error than xapi plugin, but worked ok in my case.

Thanks for the great work!

Ah good catch @andersonalipio ! We'll check that

Ping @Team-XAPI-Network

semarie

@andersonalipio I would be interested to get some elements from your installation.

your /var/log/sdn-controller-plugin.log file (on the host) in order to check the parameter passed by XO.
output of xe network-param-list uuid=$UUID (for the network concerned) or xe network-list params=all (if uuid is unknown)
output of xe pool-list params=other-config (for xo:sdn-controller:* elements)
output of xe vif-list params=uuid,network-uuid,other-config (for xo:sdn-controller:* elements)

Feel free to share it privately via PM if you prefer, possibly using https://paste.vates.tech/ .

Cc @Team-XO-Backend too (as it could be from XO side)

@andersonalipio can you also share the XOA version you're running? @semarie did a bunch of improvement on lifecycle of hosts and VM at some point XO side.

andersonalipio

@semarie I'll do it as soon as I get access to the server, hopefully tomorrow.

andersonalipio

@bleader XOA 6.7 premium (updated last friday - latest channel), as all updates on XCP-ng 8.3 from latests available updates on same day (not testing, ci or other repos)

@semarie sorry for the delay.

this output is pointless because our current rules are on network, not on VIF anymore.

@andersonalipio Let's continue the discussion with @semarie in a separate thread
