The OREC does not have the software I need. Can additional software be added?

  • It is possible to include additional software packages in VCL images; however, it is important that licensing limitations are not exceeded.

What happens if I leave my work on a VCL desktop?

  • Images are reloaded at the end of each reservation. As a result, all user created data will be lost if you do not copy the data off of the virtual desktop at the end of your session.

How do I copy data from a virtual desktop?

  • You will need to use a Secure Copy (SCP) program to copy files from the VCL desktop. If you are using a Linux or Mac computer to access the virtual desktop it will have an existing SCP client installed. If you are using a Windows computer to access the virtual desktop you will need to install a Windows SCP client, such as WinSCP.

I forgot my password to a virtual desktop that I have reserved. Where can I lookup the password?

  • Login to the VCL website. From the menu on the left hand side of the page, click Current Reservations => Connect. Your credentials will be displayed.
