i have tried to change setting of bridge in the second node, but the vmachines, later the migration, if i reboot the second node run!!
but later the other migration do not run...
thank
 
Hi,
can the guest reach the network if you start the vm on node2 (no life-migration)?
Has the client more than one NIC? Or only eth0 (-> vmbr2 -> eth0.2150)?

node2 can ping 10.0.0.1?

Which ip-adress use the guest?

node 1 have eth0-->vmbr0 ( public ip) 188.x.x.x/24 eth0--> eth0.2150--> vmbr2 10.0.0.1/28
node 2 have etho-->vmbr0 ( public ip ) 188.x.x.x/24 etho--> eth0.2150--> vmbr2 10.0.0.2/28
in this vlan 2150 ther is one block ripe/28 (guests ip block)
the 10.0.0.1 ping 10.0.0.2
but for example i create a kvm machine in the node 2 run but if i migrate in the node 1, not ping the network
for the node 1 it's the same, if i create one vmachine in the node 1 and i migrate in the node 2 not ping the network
there machines in hosted in ovh, i have tried to shutdown on vmachine and migrate but is the same
sorry for my orrible english
thank

And OVH has special config at switches to avoid mac spoofing - not sure if that can be a problem.
 
i have tried to migrate and demove and add new ethernet adapter with an other mac address.. and run..!! is layer 2 protection on vlan....
if i can solve i post here the solution....
