Abstract
A hybrid state for a virtual machine (VM) in a cloud computing system enables a VM to communicate with other VMs that belong to a virtual network (VNET VMs) while maintaining connectivity with other VMs that do not belong to the virtual network (non-VNET VMs). A non-VNET VM can be transitioned to a hybrid VM that operates in a hybrid state. The hybrid VM can be assigned a private virtual IP address (VNET address) for communication with other VNET VMs. The hybrid VM can continue to use a physical IP address to communicate with other non-VNET VMs. In this way, the hybrid VM is able to maintain connectivity with other non-VNET VMs during and after migration to the VNET. A network stack can be configured to process data packets that are destined for non-VNET VMs differently from data packets that are destined for VNET VMs.
