That is better as renaming and moving default stuff around is not such a
good idea.

openSUSE does not have it.

Doesn't vmplayer have a native command to do just that? I do not use
vmplayer as I use VirtualBox, so I have no idea if it is possible.

>From what I found a good place to start is `vmrun -T player list`, find
the vmx('s) that are running and then in a loop kill them. e.g.

for I in `vmrun -T player list|<something to get the vmx full path>`
do
	vmrun stop $I
done

Obviously this might take a bit more time then just killing it, but it
might also prevent problems with VM when you just kill it. You could also
suspend it instead of stopping it:
http://www.vmware.com/support/ws5/doc/ws_learning_cli_vmrun.html
gives more info.

Under Virtualbox this would be:
for I in `VBoxManage list -l runningvms|grep ^UUID|awk '{print $NF}'`
do
	VBoxManage controlvm $I poweroff
done
