Error that I get when running it is:

Hmm. It is arguably wrong, but it appears that it expects that the volumes attribute will include volume objects (not a hash of volume attributes). So you could do something like volume = $connection.volumes.new(volume_attributes) and then pass :volumes => [volume] in to create_vm. Worth trying as-is anyway, then we can certainly discuss a fix if that gets us to working.
P.S. that is a somewhat outdated version of fog, though updating doesn't seem like it would fix this particular issue.

Edit: deleted my own comment by accident when wanted to press edit, it is getting late here :(
To give you some background:

• I have a quite outdated vmware 4.1 infrastructure to deal with
• I've found that the latest fog brings as a dependency rbvmomi -v=1.8.1 which doesn't work with vsphere 4.1
• I haven't tried latest fog with rbvmomi -v=1.6.0, this might work fine ( unknown as of now )

Lets continue the discussion to iron out this bug, when we do finish it I can raise a github issue against fog with all necessary details if you want.

@ Revision 6 the error is linked to networks - nic type specifically.

I think you want/need $connection.interfaces.new(...) instead of $connection.networks.new(...).

$connection.interfaces.new() fixes that bit issue in Rev 6.
This is where it breaks down this time coming from

~/.rvm/gems/ruby-1.9.3-p392@fog/gems/fog-1.16.0/lib/fog/vsphere/requests/compute/get_folder.rb

which goes into rbvmomi to get the path. I think I'm giving it the right path but not apparently.

Discussion moved to fog/fog#2798
