Hi Folks,
I claiming for your help for (What I think being a routing issue).
I've rebuild entirely my network everything work well but my guest VM's on my ubuntu server have no tnetwork access.
Network set-up:

UUID: 3e2315e4-7a64-44e6-b16f-c21111d4aca5

Does any one could help me to figure out what's wrong here?
Thanks ! :)
