   ACS 4.19 RC1
   
   VMware ingestion is broken when testing with VMware 8.0.0.2as the hypervisor 
and Rocky Linux (8 or 9) - this is a consequence of changes implemented in 
https://github.com/apache/cloudstack/pull/7380:
   
   - if no record for 8.0.0.2 in the hypervisor_capabilities table, then use 
"capabilities" of the "parent" version which is VMware 8.0; 
   - if no records in the guest_os_hypervisor table, then use the 
records/mappings of the "parent" version - from 8.0
   - this all works fine during VM deployment
   - this does not work during VMware ingestion, where we do reverse-mapping, 
and code seems to look for a DB record for "rockylinux_64Guest" for version 
8.0.0.2 in the guest_os_hypervisor table - and this record does not exist
   
   The logic of "mapping minor version guest OS mappings, if missing, to a 
parent version mappings" - sounds fine, as long as:
   
   - It's supported by all ACS features/code where we try to use guest OS 
hypervisor mappings (this now includes VMware VM ingestion that needs to be 
fixed, but there might be other places)
   - there is detailed logging similar to "The guest OS mappings for XXX was 
not found for the hypervisor version YYYYY (8.0.0.2), looking for parent 
version mappings (8.0), found, using that mapping etc" - something similar to 
this, needs to be very verbose, otherwise troubleshooting will be impossible.
   
   For the hypervisor capabilities, I would propose the following:
   
   - Revert the logic of dynamically "assuming" that the minor version has the 
same capabilities as the major version (in fugure, VMware e.g. 8.5 version will 
certainly NOT have the same capabilities as the 8.0 version, it would have more 
capabilities) - so revert the code and recreated the needed DB records in the 
hypervisor_capabilities table
   - Worst case, even though it's a bad solution - leave it as it is, but add a 
loooot of logging, similar to the guest OS mappings logging (not found this, 
using that version capabilities)
