[one-users] Migration issue(s) from 3.7 to 4.2

Hi,

Something did not work in the migration process...
The HOST/VMS element you mention should have been added by this file [1],
and your VM xml is missing the USER_TEMPLATE element, which is added here
[2].

Can you compare the contents of your migrator files
in /usr/lib/one/ruby/onedb/ to the repo [3]?

Regards
