I am running one Win7 VM in VirtualBox v4.3.12. I have it setup to use 2GB of RAM. When I start the VM I can slowly see the RAM usage in the VirtualBox Web Admin page creep all the way up to 12GB before it seems to settle down. Is there a memory leak? I searched in Google and someone else said they saw something similar and had to turn off 3d acceleration in VirtualBox to fix it. Anyone have an issue with like this?
