Accordingly, this disclosure provides techniques for rebuilding a network stack of a guest operating system after the virtual machine has been moved.
由此,本发明提供了用于在迁移虚拟机之后重建客户操作系统的网络堆栈的技术。
constructing a network stack for a guest operating system of the virtual machine based on the second set of network parameters.
基于第二组网络参数为虚拟机的客户操作系统构建网络堆栈。
For example, a network stack of a guest operating system of the virtual machine may need to be rebuilt, e.g., when the destination computing device has a different attachment circuit for attaching to a virtual private network than an original computing device from which the virtual machine was moved.
In another example, which may be implemented in addition to the example above, the control unit is configured to determine the second set of network parameters for the second attachment circuit, and construct a network stack for a guest operating system of the virtual machine based on the second set of network parameters.
All hypervisors need some operating system-level components-such as a memory manager, process scheduler, input/output (I/O) stack, device drivers, security manager, a network stack, and more-to run VMs.
The computing device may begin executing the migrated virtual machine and provide the network parameters to the migrated virtual machine to cause the migrated virtual machine to rebuild a network stack for an attachment circuit for the one of computing devices 124. In this manner, the migrated virtual machine can become reconnected to the VPN using a different type of attachment circuit.
Accordingly, the application extracts the network parameters from the ICMP router advertisement message (208) and rebuilds a network stack of the guest operating system using the network parameters (210).
Therefore, after migrating a VM from a computing device of data center 108A to a computing device of data center 108N, a network stack of the migrated VM may need to be rebuilt to accommodate a new type of attachment circuit.
In this manner, using the network parameters specified in the ICMP router advertisement message, virtual machine 138N may rebuild a network stack of OS 136N and establish or re-establish an attachment circuit to a VPN, to which virtual machine 138N had been attached prior to being migrated to computing device 130.
