Abstract: Techniques are disclosed herein for migrating virtual machines. In an embodiment, path configuration information for the source virtual machine is stored within storage allocated to a source virtual machine that is managed by a first hypervisor. A source virtual disk is allocated to the source virtual machine. The source virtual disk includes storage blocks that are accessible by a guest operating system of the source virtual machine. The source virtual disk further includes at least one source management block containing data utilized by the first hypervisor to manage the storage blocks. The guest operating system of the source virtual machine is migrated to a destination virtual machine managed by a second hypervisor. A destination virtual disk is generated that includes the storage blocks that are accessible by the migrated guest operating system. The destination virtual disk further includes at least one destination management block containing data utilized by the second hypervisor to manage the storage blocks.
