Embodiment 1
[0019] like figure 1 Shown is a flow chart of Embodiment 1 of a virtual machine network connection redirection method during cross-subnet online migration according to the present invention, including:
[0020] Step 1. The virtual machine is migrated from the first subnet to the second subnet;
[0021] Step 2, the foreign agent set in the second subnet initiates a registration request to the home agent set in the first subnet;
[0022] Step 3. After receiving the registration request, the home agent establishes a two-way data transmission tunnel with the external agent;
[0023] Step 4. The data to be sent from the communication peer to the virtual machine is first sent to the home agent, and then the home agent sends the data to the external agent through a two-way data transmission tunnel, and the external agent sends the received data to the virtual machine.
[0024] Through the above method, a two-way data transmission tunnel between the home agent in the first subnet an...
