Thanks for that! Can you give me link to that doc?

all in all. Those ports "works" and they are created like that by XenServer... Is there any workaround for that?

I think We didn't have this problem with Xen Cloud Platform or Xen installed
on Xen on Debian. But it exist in XenServer6.5 (not sure if in newer).
Did you read the documentation?

        ofport: optional integer
               OpenFlow  port number for this interface. Open vSwitch sets this
               column’s value, so other clients should treat it as read-only.

               The OpenFlow ``local’’ port (OFPP_LOCAL) is  65,534.  The  other
               valid  port  numbers  are  in  the range 1 to 65,279, inclusive.
               Value -1 indicates an error adding the interface.
