[one-users] Migration to 4.0.1 problem

[André Monteiro]

Hi,

Glad Carlos found the error so everyone can be assured of a smooth
migration, nice work! After this error was removed and old VMs cleaned up
ONE worked like a charm.
About my migration, I have a sloted instalation of ONE with mySQL, always
upgrading with the source tarball and compiled on SL6.2 Using KVM
hypervisors on two similar hosts.
