How does traffic flow in OVS/VXLAN networks

Assuming VM1 resides on compute node 1 and VM2 on compute node 2; both VMs are on the same VLAN network. Further assuming both compute nodes are using OVS driver and inter-connected via a VXLAN overlay network.

When VM1 sends a packet to VM2:

Q1: How does the compute node 1 know where the VM2 is? in other words, how does it know the virtual tunnel endpoint (VTEP) of another compute node which is hosting VM2, with or without L2 Population driver?

Q2: If I have multiple tenant networks (VLAN) on the integration bridge (br-int), does every network get a patched port to the tunnel bridge (br-tun) to carry the VXLAN traffic?

Q3: Where does the VXLAN encapsulation take place? Does the entire process (striping VLAN id, adding VNI, adding outer IP) all happen on the tunnel bridge?

Thank you very much.
