Abstract
A virtualization management component of a particular host at a virtualized computing determines that a packet duplication phase of a migration of a virtual machine from a source host to the particular host has begun. The virtualization management component detects that a migrated version of the virtual machine, instantiated at the particular virtualization host, has generated a baseline packet directed to a destination address. The virtualization management component sends a first encapsulation packet comprising the baseline packet to an encapsulation intermediary associated with the destination address. The virtualization management component sends a second encapsulation packet comprising the baseline packet to the source virtualization host, with a directive to forward the second encapsulation packet to the encapsulation intermediary.
