To resolve this issue, you must disconnect the .iso image from the virtual machine, so that DRS can complete the migration.
To unmount the .iso image:
- From the guest operating system, Right-click the CD drive and click Eject.
- Right-click the virtual machine and click Guest > End VMware Tools Install.
Notes:
- If DRS is set to fully automated, the virtual machine begins to migrate automatically. If DRS is set to manual, you must migrate the virtual machine manually.
- On Linux guest operating system these steps may not resolve the issue. The virtual machine must be powered off to resolve the issue.
