[one-users] VM networking configuration CentOS

[Mark Kusch]

Hi list,

feels like an issue with NetworkManager in CentOS (not confirmed yet).
ifcfg-eth0 has configured eth0 to be managed by
`NetworkManager' (NM_CONTROLLED="yes").

Current approach is to mount and modify the qcow image
and configure NM_CONTROLLED="no".

Currently no success.
