Abstract: Disclosed is an improved approach for managing floating/virtual IP addresses in a virtualization system. Where a bare metal cloud provider does not provide adequate facilities to implement broadcast operations, the approach would capture broadcast packets, and from the captured packets, generate calls to the cloud provider to implement configuration changes to reflect the changes desired by the broadcast packets.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: Methods and systems are provided for detecting overlay end points which are a single physical hop away and employing a simplified overlay header instead of a regular overlay header for communications with the identified end points. The simplified overlay header may carry overlay protocol related forwarding and peer information and may be designed to carry locally significant forwarding information which avoids overlay lookup related overhead on encapsulation and decapsulation operations. The simplified overlay header may be handled in the same forwarding pipeline pass as the handling of the inner frame and may work across different forwarding engines. Upon detection of a single hop link/keepalive failure, the backup overlay (original overlay header) may be used for forwarding.
