I began to work on Qemu/KVM and install virt-manager to set my network. Here is my configuration: On my RedHat 32bits guest: I have 4 interfaces eth0 eth1 eth2 and eth3 with some IP addresses configured. --> eth0 has 3 VLAN (can be changed to aliases) and eth3 has one alias and one VLAN/alias. On my Redhat 64 bits host: I have 4 interfaces p1p1 p1p2 p1p3 ans p1p4 with IP adresses on the same network as the guest. --> p1p1 has 3 VLAN/aliases and p1p4 has one alias and one VLAN/alias (also same network as the guest) I set br0 br1 br2 and br3 so I can ping each interfaces: it works. But no way to set VLAN or aliases! I am mailing you because it's been weeks that I'm searching, nobody can help me in my company and there is nothing on the Internet ;( Thank you very much for your concern, Cécile Mignot </div> </body> </html>
