I've enjoyed having BT4 installed to the HD (I use Finnish keyboard layout, enjoy customisations too much and only use BT4 on the one machine to much to use a LiveCD myself) but recently I've been building a library of VMs for research purposes and have started considering the use of BT4 in Virtualbox instead which would allow easier backing up and save a dual boot scenario with Slackware.

I often see videos here produced with BT4 in VMware but how many people actively do their research and assessments using a virtual BT4 instead of HD install against physical machines on a local network?

I tend to do research work against VMs then run the findings against physical machines so any experiences with this would be appreciated.

This is not a "Can it be done" thread, I'm interested in people's tried and tested experiences over time.

Thank you very much in advance.
