Put two vNIC's on a VM and connect each NIC to a different standard switch. Is that what you want? For a VM to talk to 2 vSwitches?
yes that is exactly what i want.
i want this vm with bridge function to connect 2 standard vswitches , and another 2 individual vm connect to each vswitch seperately (vm_a connect to vswitch_a and vm_b connect to vswitch_b) , and vm_a can reach vm_b through this bridge.
