"A specified parameter was not correct" Error in the VI Client Interface When Trying to Power On a Virtual Machine (2173)

  • 52 Ratings


The following error message appears and the virtual machine does not power on:
A specified parameter was not correct.
Note: This article is specific to this error message on VMware VirtualCenter 2.0. If you are receiving this error message on other versions of this product, contact VMware Support. For information on opening a support request, see How to submit a Support Request.


This error occurs because disk space is low on your datastore where the virtual machine is located. During power on, enough space must be available to store the swap file associated with the virtual machine. Typically, this is equal in size to the amount of memory allocated to the virtual machine. A large-memory virtual machine (that is, a virtual machine allocated 4GB of RAM) requires 4GB of free disk space on its datastore in order to power on.

To fix this issue, free up enough disk space on the datastore and power on again.

Note: This issue is fixed in VirtualCenter 2.0.1. The error message no longer appears and you can power on the virtual machine.

For information on a similar error message reported in vCenter Server 4.x, see Powering on a virtual machine fails with the error: memoryAllocation.reservation (1036914).
