Hello all! Has anyone had success using Network Configuration Profiles with vCenter 7? I've setup a network profile using David's instructions here: https://www.virtualthoughts.co.uk/2020/03/29/rancher-vsphere-network-protocol-profiles-and-static-ip-addresses-for-k8s-nodes/ Rancher (2.7 & 2.6.9) deploys the VM, but at power on, errors. Out of IP addresses on network x

Obvious question - are you out of assigned ips in that pool? What is shown when you hover your mouse over the red exclamation point?

Yes, this is a fresh setup...no IPs have been allocated yet. I have a case open with VMware to hopefully figure out what the issue is. Getting a similar issue in vCenter deploying a VM directly in vCenter and enabling vApp Options to use the pool. There are ips in the pool, but vCenter does not "see" them.

@blue-jelly-47972 Another question, what does your ip address assignment look like in the network profile? Not looking at the numbers but more the syntax at the end.

Not sure what you mean by "syntax at the end", but here's the Profile

Ip address looks wrong
In the vapp

ah yeah, I see that -- should be the portgroup name. I was testing by network profile name vs the portgroup name
same thing

No the formatting is wrong

Ip range is different from subnet?

blue-jelly-47972

12/11/2022, 10:09 PM
ip range is a /21 so 10.7.8.0-10.7.15.254

Ok. Sounds like a vmware thing. Let's see what they come back with. What version of vcentre and esxi do you have

7.0.3 -- mix of f and g on the hosts.
thank you for your input... really do appreciate your time! 🙂

Interesting. At work and home I have vcentre 7 and 6.5 esxi and they both work.
If it was me for troubleshooting purposes I would try with 24, instead of 21 and the ip address pools on the same range as the subnet mask
If that works Then troubleshoot from there as a base. Because for me I know that this approach works. I have implemented it on two sites
