Unable to create instance with knife.

[jjasghar]

This is throwing an error here: https://github.com/fog/fog/blob/master/lib/fog/rackspace/core.rb#L145

It looks like fog.io updated this recently too. I'm betting the issue lies with fog not this gem. But i'd like someone else to reconfirm this.

I've begun testing it by downgrading fog then removing the newer version (so it would stop using it)
So far I've recreated the issue on:
fog versions:
1.27.0
1.26.0
1.25.0
1.24.0

Last error I saw:
/usr/local/share/gems/gems/fog-1.24.0/lib/fog/rackspace/core.rb:141:in escape': undefined methodgsub' for 2:Fixnum (NoMethodError)

This would be easier if I had a version number to test against. Any idea when the change came out?

Utilizing fog I am able to create a machine:

server = Compute.new({:provider => 'rackspace', :rackspace_region => :dfw}).servers.create({:name => "Test Fog Instance", :flavor_id => 2, :image_id => "8aac6fb5-4bd3-4256-bf6e-ff8500bf60cd" })

It looks like it's an issue w/ passing the flavor ID as an integer vs a string, which makes it interesting that you can do it directly in fog w/ :flavor_id => 2 rather than :flavor_id => "2".

However, before you go any further you might want to take a look at the list of supported server flavors. In case you're not aware, flavor ID "2" (for "512 MB Standard Instance") is "being phased out and should not be used for new servers". I recommend updating to the smallest general flavor: "general1-1", a "1 GB General Purpose v1".

@jjasghar actually I see this is coming from a default value in this gem, so it probably makes sense to change the default value at https://github.com/chef/knife-rackspace/blob/c05cf2161bac8a010238e7d4fe7b492d0c760989/lib/chef/knife/rackspace_server_create.rb#L49 from 2 to "general1-1".

I can confirm:
The following commands get past the error above using rackspace-knife(0.10.0) and fog(1.27.0):
[wlightning@test-management-server ~]$ knife rackspace server create -f 2 -I 8aac6fb5-4bd3-4256-bf6e-ff8500bf60cd

This appears to be purely a problem with the default behavior. I also successfully passed a -f "2". This purely seems to be an issue when no flavor id is passed.
