@rhtyd @jburwell @karuturi I confirm the same issue with this PR as with
'CLOUDSTACK-5922:Incorrect handling RHEL guests for 5.5 to 5.9
When Os type is specified as Ubuntu 16.04

and VM is started on VmWare it actually creates VM with OS type 'Other
(64-bit)'

The fix was to put a respective entry into
vmware-base/src/com/cloud/hypervisor/vmware/util/VmwareGuestOsMapper.java
https://github.com/apache/cloudstack/commit/05c6b455ae89480d84ba5dfa4dc79d3336ebd458
Can we roll back this PR and make it right? An alternative path wold be to
figure out why adding entries into tables is not good enough and why changes in
the code is still required.
