ISO update (as recommended) for my pool of three XCP-ng 8.3 RC1 hypervisors.
Everything went perfectly for each server.
I had to reinstall the additional packages (traceroute vim-enhanced mtr etc...), re-enable LLDP advertisements on the network interfaces (lldptool -L -i eth0 adminStatus=rxtx) and recreate the multipath configuration file (/etc/multipath/conf.d/huawei.conf).
In short, nothing seems abnormal.

:@stormi For us, the openvswitch-2.17.7-2.1.xcpng8.3 update has definitively solved the problem of overlay networks that weren't working (thanks David M. for all your help and hard work).
Unfortunately, the sm-3.2.3-1.1.xcpng8.3 update seems to have broken something in our iSCSI sessions. We now have 3 sessions instead of the usual 4 (2 interfaces on the host to two controllers on the storage array).
We have a less-than-ideal configuration with a large, flat network ( we have a project planned to put everything back the way it should be) with interfaces named c_eth4 and c_eth5, as recommended in the documentation in such cases.
It seems that the new version respects the use of interfaces for one of the two targets, but not for the other, which uses the default interface.

yum downgrade sm sm-fairlockI can confirm that it works again on 4 paths via both interfaces after downgrade.
