I have an OpenSuse server that runs some services (including Apache web server, mailing list, etc.). Now I need to move all these service to a virtual machine (Virtualbox could run on the same physical machine or somewhere else).
It's ideal if I can "copy" everything to the VM so that the VM will work exactly as the original machine runs. All the user's data (/home/*) is stored in an NFS, that should not be transfer to VM. Then I can have a relatively small (several Gigabyte) VM image so it could be backed up every several days.
I need all the system and application settings be moved to the VM, so I can switch to use the VM smoothly.
Is there any tool or something can do this simply? If not, how should I do this?
