## The design and implementation of hypervisor
### The requirements:
-to implement a mechanism which help pfinet servers communicate with each other. For example, if pfinet 1 has IP A and pfinet 2 has IP B, the packet sent by pfinet 1 with destination address IP B should be received by pfinet 2.
-Sub-hurd should be able to use this mechanism to communicate with each other.
-Meanwhile this mechanism should allow non-privileged the user to start his own pfinet.

### The possible approach is to create a hypervisor whose roles are:
- 1. to create some virtual network interface, so pfinet can send packets to it.
- 2. to receive the packet from pfinet, and forward the packet to other pfinets in hurd
- 3. or forward the packet to the real network device in the kernel and send it to the network.
- 4. to guard the network traffic and filter illegal packets (forged by some malicious users) from pfinet or some other programs.

### To create a virtual network interface:
Implement the RPC interface defined in device.defs just as "boot" does.
-Publish the port, so other programs can get the port and open the virtual device by calling device_open(). The hypervisor now works as a translator and other programs can get the port by calling file_name_port().
