It was 33rd in 2010:
In November 2010, the Air Force Research Laboratory created a powerful supercomputer, nicknamed the “Condor Cluster”, by connecting together 1,760 consoles with 168 GPUs and 84 coordinating servers in a parallel array capable of 500 trillion floating-point operations per second (500 TFLOPS). As built, the Condor Cluster was the 33rd largest supercomputer in the world and was used to analyze high definition satellite imagery at a cost of only one tenth that of a traditional supercomputer.

I work around this by enabling rdp or ssh on guests as soon as possible and connect from my terminal for ssh, I use remmina for rdp, paste works there.
I don’t know other situations where I would need this.
