Selecting Multiple Virtual Machines and Attempting to Migrate Them All Concurrently Might Fail (1383)


Why can I not migrate multiple virtual machines at the same time?


While migration and migration with VMotion of multiply selected virtual machines typically succeeds, VMware does not recommend this as a common operation practice due to two known issues:
  • pre-migration checks conducted on a virtual machine prior to a migration with VMotion are circumvented
  • failed migrations might fail to generate a pop-up dialog and will only appear in the task list

VirtualCenter performs a pre-migration check on any virtual machine as part of the pre-process for a migration. When multiple virtual machines are selected, this cannot be completed. Consequently, migration of the virtual machines might fail.

When migrating or migrating with VMotion multiple virtual machines simultaneously (through a multiselect and drag), popup error dialogs are not generated for any failed migrations or migrations with VMotion.

When doing a single migration with VMotion, certain failures can generate popup error dialogs. However, if you are doing a drag of multiple virtual machines to initiate multiple migrations with VMotion, some failure cases will not generate popup error dialogs.

Refer to the task list to view the reasons for any failures.
