Question looking for advice about VM's


Hi,

I have 5 machines, all under Nux OS (One nux as firewall, one Debian's like, one Ubuntu 9.04, one Ubuntu 10.04 and one Debian Lenny).

All web and various servers installed on the Debian'machine. I recently made a huge shell mistake (remote rm with an empty data in a cronjob, well done ...) and had to reinstall from scratch the Debian's machine. Great fun with special Apache and PHP compiled.

So I spent quite a lot of time to set up some back up cronjobs on all these machines.

And I tried to install a VM (virtual box on the Debian machine) as it looks like to offer some significant advantages, like adding another distro, or ... enabling easy backups, as it would be an entire (virtual) disk.

I've installed the VM and it looks running on the Debian machine.

=> Questions: Assuming this would be a good choice, how to access and manipulate the VM from a remote machine on another subnet on my LAN ..? (could not find a detailed HOWTO for noobs)

Thx in advance

Access to a VM is transparent for the most part. Only thing you may need to be aware is the three basic ways one can setup the virtual network. One is bridged, another is nat and another is local. Local would only allow VM's to network. Remember the VM application has a router software sort of hidden for both nat and local. I tend to use nat so you have to watch your routes to any VM.

Setup the VM network in bridge mode and you can access the VMs over the network the same way as a physical box.

Thx guys.

In the case I would use that VM to embed an Apache web server (inc. an FTP server as well, PHP, MySql, Ajax and so on..), what would be the best way between a bridged or a natted "virtual router" ?

(I understand "nat" but did not experienced yet a bridge connection, so NAT looks easier for me, but a bridge might be a better choice)

Thx in advance
