Howto choose partition with bigsuds to get VirtualServer

Hello,

I have several partitions on my LB and I try to get VirtualServer with bigsuds But when a use it to ask VirtualServer, I have only VirtualServer defined in Common partition. Below an extract of my code

bigip_api = bigsuds.BIGIP(bigip_access_point, bigip_user, bigip_password)
print bigip_api.LocalLB.VirtualServer.get_list()

How can I get VirtualServer for all partitions or VirtualServer for a dedicated partition ?

Thanks in advance for your help.
