+------------------+ +------------------+
| Hypervisor1 | | Hypervisor2 |
| +-----+ | | +-----+ |
| | VM1 | | | | VM2 | |
| +--+--+ | | +--+--+ |
| | (vnet0) | | (vnet0) | |
| +--+--+ | | +--+--+ |
| | br0 | | | | br0 | |
| +--+--+ | | +--+--+ |
| | | | | |
| (ethws0) (eth0) | | (eth0) (ethws0) |
+----||--------+---+ +----+-------||----+
 || | +---+ | ||
 || -----+--------| R |--------+----- ||

then you can type following commands.

# etherws server
# brctl addbr br0
# brctl addif br0 vnet0
# brctl addif br0 ethws0
# ifconfig br0 up


on Hypervisor2:

# etherws client --uri ws://< Hypervisor1's IP address >/
