I have a HP laptop with decent specs:
- Processor: AMD A8
- Memory: 4 GB
- Graphics: 1.5 GB (1x 512 MB integrated, 1x 1 GB dedicated; configured in CrossFireX)
- Operating System: Windows 8 x64
I have installed Ubuntu 13.04 on a VirtualBox virtual machine and have allocated 1 GB of RAM and 1 processor core to it.
The problem is the VM runs painfully slow. When I allocate similar configuration to another VM running Windows 7, it works just fine, even with Aero turned on.
Another problem is when I switch to any VM with mouse integration on, and I switch back to the host OS, the trackpad swipe gestures stops working, even after switching off the VM(s).
