Abstract
Techniques for optimistic locking of virtual machine instances during a migration are described herein. Application programming interface requests are classified by type. When a request such as an application programming interface request is received during the migration of a virtual machine instance from a source location to a target location, the request is classified according to the type and according to the state of the migration. Based on that classification, it is determined whether to block the request, allow the request, or cancel the migration.
