Re: [uyuni-users] VMware cloned VM's are treated as one system in Uyuni - SOLVED

31 Mar 2020

      Apologies for my failure to RTFM

This is indeed documented in
https://www.uyuni-project.org/uyuni-docs/uyuni/administration/tshoot-registe...

Thanks for the pointers Nicola and Tobias!

I have a VMware CentOS7 VM which was cloned from another.  When I
import the first as a Salt client everything is fine.  When I go to
register the second, a new salt key is generated for the second hostname
but when the key is accepted, some attributes of the original registered
machine are replaced by the second.  In other words, a second registered
system is not created, the first system is converted into the identity
of the second.
The UUID in Uyuni is NOT changed to the hardware uuid of the second
machine; 
The system name IS changed to the second machine; 
The hostname and ip address remains set as the first machine. 

UUIDs in the individual VM .vmx files are different
Hardware uuids revealed by dmidecode for each VM are different
ifcfg scripts on each VM contain unique uuids for the network
interfaces
IPv6 address for each system are different 

I've recovered all the salt grains.items by registering each server
separately and there is no duplication of any grain value I can find. 

In short the systems appear to be unique but Uyuni thinks they are the
same.

Interestingly both systems were originally registered separately
without this problem in Spacewalk version 28

Any ideas as to what to look for next?!
