CS 4.11 : Error display fresh install

[Olivier GUIN]

Hello,

I juste install fresh CS 4.11
Manager CentOS 7
Cloudstack 4.11 from repo
Host Xen 6.5
Secondary and primary are under nfs for the moment

when I display 'Infrastructure' I have 3 Hosts, 2  SystemVMs 0 Virtual 
Routers

But When I go to Hosts I have only this message : 'No data to show'
But When I go to System VMs I have nothing only 'sablier' !

Do you know this problem?
Best regards,
Olivier
