I have a Windows 10 machine, with VirtualBox v5.0.16 r105871 installed. Over this, I am trying to host an Ubuntu 14.04.4 OS so that I can install and run the Robot Operating System (ROS). Here are some screenshots that show my setup:
The initial install of ROS desktop needs about 1.5GB, so I allocated 4GB of space for the Ubuntu OS. During installation, I run out of memory. This is the screenshot from Terminal:
So I go into the System Monitor to check. But everything looks fine - I have 4 GB and 3GB more to go:
I followed the installation instructions at the ROS Indigo installation site to reach this point, and I'm stuck. I highly suspect that has nothing to do with ROS and can be solved if I can get the Ubuntu OS to recognize all 4GB of the disk, but I don't seem to be fiddling with the right controls.
Any help or guidance would be appreciated, thanks in advance!
