can't create servers until virtual router is initialized

[kcbraunschweig]

If you are using virtual networking, knife cs server create will fail if the virtual router has not been initialized, with the error below. The workaround is to create a vm instance via the webui. This will initialize the router. After that knife cs will work properly.

$ knife cs server create vrweb0 -S M -x foo -P bar-r 'role[base]' -VV
