Which happens if the swap file of a virtual machine is inaccessible to the destination host during a vMotion?

If the designated swap file location cannot be accessed by the destination ESXi host, vSphere creates a new swap file in the VM's home directory - the same location as the .vmx configuration file - on a datastore that is accessible to the destination host. This behavior allows vMotion to complete successfully without requiring the original swap file to be accessible or transferred.

The swap file is not copied from the source to the destination host's local storage during vMotion; a new swap file is instead created at the destination in the VM's home directory on an accessible datastore.

vMotion does not fail when the swap file is inaccessible to the destination host; vSphere handles this scenario automatically by creating a new swap file alongside the VM configuration file.

vSphere does not replicate the existing swap file to a mutually accessible datastore; it creates a new swap file at the destination in the VM's configuration file directory on any datastore accessible to the destination host.
