Task Description:

It'd be nice to be able to specify memory and disk using units such as GB or MB instead of being forced to use MB all the time. I believe ganeti will allow that (at least on the command line) but you should check the RAPI to be sure you can pass that info too.

Some examples include:

1GB
1024MB

I'm not sure if you want to include all forms (i.e. G, GB, gb, etc) or force GB/MB. Whatever makes it easier in the backend probably.
