Re: [AMBER-Developers] [AMBER] Installation of Amber in Cygwin

I tried Ubuntu 12 Windows Installer a few weeks ago. It is really
meant for people Dave is referring to, but there are some serious

Pros: It installs like any other Windows program on a Windows machine
and takes care of dual boot automatically. Basically, virtual machine
and Ubuntu 12 are integrated AND the VM uses the real hardware
(graphics, network, etc.), which is generally not the case with VBox
or VMware.

Cons: The maximum size of the VM is 30 GB, but the real problem is
that file I/O is fairly slow and often makes the VM seem to freeze.
The reason, I believe, is that the VM actually uses NTFS via
mount-ntfs, which constantly drains the CPU resources. I haven't
tried it yet, but using /dev/shm for file I/O might solve this problem
if there is enough physical memory available.
