You want the "appliance" image, or a service that provides you with hosting 
for virtual machine?

For the former, you can get lots of prebuilt images. For instance:

http://www.enomalism.com/downloads/download-virtual-appliances/
http://www.vmware.com/vmtn/appliances/directory/
http://virtualappliances.net/downloads/

I use KVM/QEMU for all my own virtual machines. VMware is slightly faster 
than QEMU on CPUs without KVM support. With qemu-img you can convert VMware 
images for use with QEMU or vice-versa, with a couple limitations (e.g. 
driver issues since emulated hardware is different; can't emulate an ARM on 
an x86 with VMware, etc).

I personally find it's easiest to make my own images quickly and easily by 
starting with a clean base image (i.e. an up-to-date minimal Debian stable 
already set up with testing/unstable/experimental pinning) and just 
installing whatever I need on top of that. But see below:

One downside of most "appliance" images (including ones I usually make 
myself) is that they are NOT "nano" by any stretch. Almost everything is 
built on top of some normal operating system, like a Debian or Slackware 
install (or, worse, something like Windows XP).

But this is also an "upside" since it generally makes them easy to 
administer, configure, and use. For example, a "nano" web server sounds 
great, until you realize that you have to give it files to serve somehow, 
and oh, you wanted to run a rails application, and ... etc ....
