Comment 2 for bug 497955

I think the GUI should add the helpful info I got from entering 'testdrive' from the command line (see below). Test Drive should also detect whether kvm or virtualbox is best for one's PC.

Not knowing how to install the patch, I installed virtualbox-ose. Seems to be working as advertised now.

My output was as follows:

matt@matt-laptop:~$ testdrive
  1. Ubuntu Desktop (lucid)
  2. Ubuntu Server (lucid)
  3. Ubuntu Alternate (lucid)
  4. Ubuntu DVD (lucid)
  5. Ubuntu Netbook Remix (lucid)
  6. Other (prompt for ISO URL)

Select an ISO to testdrive: 1

ERROR: You must have either /usr/bin/kvm or /usr/bin/VBoxManage installed.
HINT: Consider installing kvm if your CPU supports VT, or virtualbox-ose...
 egrep "flags.*:.*(svm|vmx)" /proc/cpuinfo && \
   sudo apt-get install kvm || \
   sudo apt-get install virtualbox-ose

matt@matt-laptop:~$ ^C
matt@matt-laptop:~$
