An administrator is attempting to power on a virtual machine with 32GB of memory. The operation fails with the
following error:
Could not power on VM: No space left on device
Checking the space on the virtual machine’s datastore, there is 30GB free.
Which action would allow the VM to power on?
A.
Set a 2GB memory reservation on the VM.
B.
Mount the virtual disk from the affected VM on to another virtual machine and free up space from within the
OS.
C.
Enable vSphere HD admission control on the cluster in which the VM resides.
D.
Set a 2GB memory limit on the VM.
Explanation:
You must reserve swap space for any unreserved virtual machine memory (the difference between the
reservation and the configured memory size) on per-virtual machine swap files.
