  1. On a PC unzipping is a two step process. The first unzip results in the file RHESSysWorkflows-VM-201501.tar. Unzipping this again is needed to obtain the folder with virtual machine files.
  2. When I first opened the virtual machine. I received the error "Failed to open a session for the virtual machine ... Implementation of the USB 2.0 controller not found! To resolve this I went to settings USB and unchecked the Enable USB 2.0 EHCI Controller that was checked by default. Then the machine launched. untitled

Just curious, did you install the VirtualBox Extension Pack and still get the USB 2.0 error?

dtarb commented 9 years ago

No I did not. Honestly I just blew by that in the instructions without noticing, since I had virtual box installed anyway. However if you go to virtualbox.org you do not see it immediately and need to go to downloads to find it. Lame excuse I know...

I am assuming that now that I have worked around the USB issue that I do not need the extension pack for anything. Will we need USB for your workshop.

The main reason to install it, aside from avoiding the error message, is if you would like to transfer data out of the VM by copying to a USB volume (and not have it take forever over USB 1.1; not sure why Oracle does not include USB 2.0 support in the opensource part of VirtualBox, it's only been a standard for 15 years). Of course you could also setup a shared folder to copy data to the host filesystem.
