An VMWare player "appliance" is really just a disk image & config file.
Running a disk image in QEMU is just a matter of executing

   qemu -hda /path/to/image  

Perhaps adding "-m XXX" to set increased  RAM.

This is no harder to do than using VMWare player

  vmplayer  /path/to/appliance

Since QEMU already understands VMWare disk images, there's even a good
chance that QEMU can run a VMWare "appliance" image itself. So it looks
to me that QEMU is already on a par with VMWare player in terms of being
able to quickly & simply test 'appliance' images.
