Methods, systems and computer program products for deploying a virtualization system onto cloud computing infrastructure. Virtual machines of a virtualization system are deployed onto computing nodes that are interconnected via a cloud provider's networking infrastructure. When migrating a virtual machine from a source computing node to a target computing node that is also interconnected to the cloud provider's networking infrastructure, the addressing of the to-be-migrated virtual machine changes. Dynamically-updated media access control translation tables are maintained at the computing nodes. The media access control translation tables are populated with cloud provider media access control addresses received from the cloud provider. A virtual switch at each computing node modifies incoming and outgoing packets of a to-be-migrated virtual machine based on contents of that node's media access control translation table. On an ongoing basis, addressing information for migrated virtual machines is received at the computing nodes by operation of address resolution protocols.

Virtual machine migration in cloud infrastructure networks

Methods, systems and non-transitory computer readable media for handling IP network addresses in a virtualization system. Embodiments are configured to receive, from a cloud provider, a cloud provider media access control address to assign to a network interface of a computing node. Also received from the cloud provider is a cloud provider's IP address associated with the cloud provider's media access control address. A virtual machine on the computing node is configured such that the cloud provider's IP address serves as an IP address of the virtual machine and such that a virtualization system media access control address serves as a MAC address of the virtual machine. The virtualization system correlates the cloud provider's media access control address to the IP address of the virtual machine. In some cases, the cloud provider's media access control address stored in a virtual switch of a hypervisor.

Handling IP network addresses in a virtualization system

Disclosed is an improved approach for updating address mappings when migrating a virtual entity in a virtualization environment that is installed onto a bare metal cloud infrastructure. The solution reacts to VM migration events rapidly and converges faster with minimal packet loss, as well as avoiding any interruption to existing connections between the VMs.
