Well it's quite difficult to debug your issue.
I can tell only what helped me in such cases :

 1. Get the vnet interfaces from your VM (virsh dumpxml s-xx-VM)  2. Get bridge 
infos using brctl show  3. Log into the system VM from the hypervisor as root 
using ssh -i
    .ssh/id_rsa.cloud [email protected] -p 3922 ( The IP is the link
    local IP)
 4. Check each interface if you can ping gateways

Bye,
Bjoern
