I have vCloud Director with many vCenters connected. Each vCenter has “it own” organization VDC. After upgrading vCloud Director from 8.20 to 18.104.22.168 organization networks used in vCenter A are visible in all org VDC.
Networks from different vCenters visible in all org VDCs
This causes many issue. For example when building new virtual machine and you choose network from different vCenter, build will fail. And because I have similar network names in vCenters, it is difficult to tell, if I’m choosing correct one.
Issue was reported to VMware. It looks like a known issue, but there is no KB or workaround for it. Issue will be resolved in the next release of vCloud Director 9.5 which is scheduled for early October 2018.
