what if one of the tokens are null/empty? why not simply add the hostname
(if only it's not null/empty) at the end of vmInternalCSName; simply do a
`vmInternalCSName + "-" + vmSpace.getHostName()` (iff
!Strings.isNullOrEmpty(getHostName()))
Using the same internal CS name on vmware should be alright and ideal,
solve the issue of inconsistent and unique naming.
