VIF isolation with shared network

[Mārtiņš Jakubovičs]

Hello,

I created shared network in advanced zone with network offering which 
don't have services. I want that user add this network, manually 
configure network in VM and use this network. But I stick with problem, 
that users can set different IP to VM and use this network anyway. Is it 
possible to use something like vif-locking which is available in XenServer?

Thanks.
