I use Cygwin in a (VMware Player) VM with XP all the time and it's not
like you describe at all. I think the main Cygwin developers also use
VMs (at least from time to time), so there's nothing intrinsic to
running in a VM that causes the performance you describe.

I can't say for sure what your problem is, but I'd start by checking
your PATH for any directories on a remote machine (including any "host"
directories provided by your VM software). Or, perhaps simply try

  $ PATH /bin /bin/ls

and see if your problem goes away.

If none of that works, follow the directions here:

No.
