That sounds like a likely candidate. I've only used VMWare server before
(the free one, not expensive GSX server), so I have no experience with
Virtual Box. Can you tell me five things about it?
1) Will it allow you to setup a network interface that acts as a pass
through to the host network (i.e. if the HOST box gets 192.168.20.5 as it's
IP, can the guest OS use 192.168.20.6, on the same network) without using
bridges or the like?
2) Does it simply pass the MAC of the HOST network interface as the MAC to
the guest boxes (VMWare server does that), or does it generate new MAC
addresses for it's boxes? If it does generate new MAC addresses, is there a
place where those can be seen/changed on the HOST file system?
3) Does VirtualBox allow you to start it, and it's machines, as soon as the
computer boots up?
4) Does VirtualBox allow for Copy-on-Write to it's hdd image files? (VMWare
server doesn't, but I hear GSX server does)
5) Does VirtualBox maintain the USB connections between system boots? I.e.
if the system goes down (say due to power failure), then comes back up,
will the rebooted systems automatically get their assigned USB devices
back? Or would I have to reconnect them manually?
I appreciate the information on this! It's going to be a big help!
