View source for Wake-On-Lan fail with VM

== How Wake-On-Lan Work ==

*Cloud server will request "Agent1" to wake up another "Agent2"
*Agent1 will send broadcast magic packet which payload is the MAC address of Agent2.
*When Agent2 receive magic packet, it power on device.

== Routing Table Problem with VM installed ==

*There are two broadcast address.
**Global broadcast address: 255.255.255.255
**Local broadcast address: ex: 172.22.15.255

**PowerOnOff plugin send WOL packet to global broadcast address.

*We found VM network adapter will modify global broadcast route rule that may makes broadcast fail.

*Routing priority of windows:
*#Small metric rule will pick up first.
*#Then it will pick up the first interface that avaliable.
*PowerOnOff plugin will choose "255.255.255.255 | 192.168.189.1" rule from routing table in this example.

== Possible Solution ==
*Send WOL packet with local broadcast address to each interface in current agent.
