 * GCE allows per-user SSH key specification, but Nova supports only one key.
 Solution: Nova GCE API just uses first key.
 
+* Default Openstack flavors are available as machine types. GCE doesn't allow symbol '.' in machine type names,
+that's why GCE API plugin converts symbols '.' into '-' in 'get' requests (e.g. request of machine types converts
+the name 'm1.tiny' into m1-tiny) and vise versa in 'put/post/delete' requests (e.g. instance creation converts
+the name 'n1-standard-1' to 'n1.standard.1').
