high-memory host-memory insufficient-memory-cpu-disk memory-overcommited sufficient-host-memory increase-ram

Resolution

Note: If you are seeing this error after installing Service Pack 1 for Windows 7 or Windows 2008 R2, see After installing Windows 7 SP1, VMware Workstation reports the error: Not enough physical memory is available to power this virtual machine (1036185).

This error is generated when the VMware application is unable to reserve the memory (RAM) necessary to successfully power on or run a virtual machine. Typically, this occurs when the memory allocation settings for a virtual machine do not match the resources available on the host.

To resolve this issue, decrease the memory assigned to each virtual machine, increase the amount of physical memory installed in the host, or both.

For more information about making changes to:

VMware Workstation and Player, see the VMware Workstation 4.5 Memory Usage Notes.

VMware GSX Server, see the VMware GSX Server documentation.

VMware ESX, see the Resource Management Guide for your version of ESX.

VMware Fusion, see Resolving the VMware Fusion error: The virtual machine is unable to reserve memory (1014958).
