A vSphere administrator is unable to vMotion a virtual machine between two hosts. An error message indicates that the USB device is not accessible on the target host.
What is causing this issue?
A. The USB device was not enabled for vMotion when it was added to the virtual machine.
B. ESXi does not support vMotion with a USB device attached to the virtual machine.
C. The VMkernel port for vMotion is not enabled for USB traffic.
D. The virtual machine has the wrong USB controller installed.
Correct Answer: A
Explanation/Reference:
Explanation:
A: You must select all USB devices on a virtual machine for migration for vMotion to be successful. If one or more devices are not enabled for vMotion, migration fails. You must remove then re-add the USB device and enable vMotion for a successful migration. The inability to vMotion between the two hosts could be that the USB device was not enabled and thus not accessible.
Incorrect Answers:
B: An ESXi host can indeed migrate a vm and maintain USB passthough connections to the original host provided that all the USB devices in question are connected and enabled for vMotion.
C: This is not a VMkernel port issue but rather a USB device that was not enabled for vMotion.
D: The virtual machine USB controller is not the problem; it is a case of a USB that was not enabled for vMotion when it was added to the virtual machine.
