VMware vSphere

8.0.3

Description

I have a terraform script that performs a clone operation on a VMware template created with packer. In the terraform script I add two NICs to the existing VM (for a total of 3) and then configure IP information on all three.

What I see is that the new NICs in Rocky Linux are configured but duplicated:

ens256 VMware customization ens256 ens224 VMware customization ens224 ens192 VMware customization ens192

I am running openvmtools on the system. It seems like network connections are getting created in two places:

The ens connections are created in /etc/sysconfig/network-scripts, and the "Vmware Customizations" connections are created in /etc/Network-Manager/system-connections

I don't think connections are supposed to be created in both locations and obviously, we don't want our NIC/connections named "VMware customization xxxx"

Is this a bug in the VMware terraform provider, openvmtools, Rocky Linux?
