The disclosure provides an approach for dynamically reprogramming network and network infrastructure in response to VM mobility. The approach provides a hypervisor layer that can observe changes in VM-host relationships and reprogram the associated network and network infrastructure to maintain network communication. The hypervisor layer notifies a controller of a data center to migrate an ENI of the migrated VM to the same destination host as the migrated VM, in response to VM migration.

Reprogramming network infrastructure in response to VM mobility

The disclosure provides an approach for dynamically reprogramming network and network infrastructure in response to VM mobility. The approach provides a hypervisor layer that can observe changes in VM-host relationships and reprogram the associated network and network infrastructure to maintain network communication. The hypervisor layer notifies an elastic network interface of a new IP address to include within its whitelist in response to VM migration to that elastic network interface.

A method for migrating a virtual machine disk (VM disk) from first physical storage to second physical storage while the virtual machine (VM) is running, the method comprising: (a) creating a first child VM disk to which writes are redirected from a first parent VM disk, the first parent VM disk being on the first physical storage; (b) copying the first parent VM disk to the second physical storage as a second parent VM disk; (c) re-parenting the first VM child disk to the second parent VM disk; and (d) consolidating the first child VM disk and the second parent VM disk.

Online virtual machine disk migration

A method for migrating a virtual machine disk (VM disk) from first physical storage to second physical storage while the virtual machine (VM) is running, the method comprising: (a) taking a snapshot of the VM disk as represented by a first parent VM disk stored on the first physical storage, whereby a first child VM disk is created on one of the first or second physical storage; (b) copying the first parent VM disk to the second physical storage as a second parent VM disk; (c) re-parenting the first VM child disk to the second parent VM disk; and (d) consolidating the first child VM disk and the second parent VM disk.
