Windows – virtualbox virtual hard drive on external hdd (ubuntu guest on Vista host)

Ubuntuvirtualboxvirtualizationwindows

Guest VM : Ubuntu 9.04
Host : Vista
Phys RAM : 4GB
Guest RAM : 1.3 GB
processor : core duo
disk for guest : 18GB

I am new to virtual machines. Although, VirtualBox has been very user friendly, I have few doubts (perhaps from concepts of virtualization)

1) I was thinking of creating the virtual hard drive (vhd) for guest (ubuntu) on my external hdd? is this alright?

2) Given the physical RAM (3GB accessible from 4GB – Vista 32bit) Can I work on both the guest and host together (interchange often as every 2-5 mins)? will that be a problem?

Thx in advance.

EDIT (updated app usage): I plan to use eclipse/netbeans with running Jetty on Ubuntu and OfficeApps-outlook,IMs,spreadsheet.. (everything else) on Vista.

You should not have any problems creating the virtual disk on the external drive.

What applications will you be using?
