Fixing Low Memory Warning in VmWare-Hosted Windows Environments

VMware Workstation is one of the best virtualization software packages for Windows. However, some users see an error message when they try to start virtual machines in VMware Workstation. That error message says, “not enough physical memory is available to power on this virtual machine,” and virtual machines won’t start up.

This VMware issue can arise when there’s more than enough RAM available on a PC. However, there are numerous possible causes for the “not enough physical memory” error. This is how you can fix the “not enough physical memory” WMware error in Windows 10 and 11.

1. Configure VMware to Run as an Administrator

Not running VMware as an administrator places restrictions on its system permissions and access to resources. So, run the software with elevated rights to ensure a lack of permissions isn’t causing any issues.

You can check out how to run any program as an administrator on Windows for more help, or you can set VMware to always run as an administrator like this:

1. If there’s a VMware shortcut on your desktop, right-click it and selectOpen file location. Manually open VMware’s installation directory in File Explorer if you can’t right-click a shortcut for the software.
2. Then click the VMware EXE file with the right mouse button to select itsProperties context menu option.
3. SelectCompatibility to view that tab’s settings.
4. Click the checkbox for theRun this program as administrator option to select it.
   
5. SelectApply to save the new administrator option for VMware.
6. Then selectOK to close WMware’s properties window.

2. Edit the Config File

Lots of users have been able to fix the “not enough physical memory” by editing VMWare’sconfig.ini file. Those users disabled a Host parameter within the software’s configuration file. To disable that Host parameter, open and edit VMware’sconfig.ini file as follows:

1. PressWin + E to access File Explorer.
2. Open this VMware directory in Explorer:
   C:\ProgramData\VMware\VMware Workstation
3. Right-click theconfig.ini file and selectOpen with .
   
4. SelectNotepad to view the configuration file in that text editor.
5. Then input vmmon.disableHostParameters = “TRUE” at the bottom of the configuration file as in the image below.
   
6. ClickFile on Notepad’s menubar.
7. Select the menu’sSave option.
   

3. Expand the Virtual Memory for the Virtual Machine

The “not enough physical memory” error can occur because not enough virtual memory has been allocated to the virtual machine. You can expand a virtual machine’s memory allocation in VMWare like this:

1. Open your VMware software.
2. Right-click the virtual machine for which you need to fix the error and selectSettings .
3. Increase the virtual machine’s memory allocation with the bar slider. That amount should always be higher than your PC’s available RAM.

6. Perform a Clean Boot

Performing a clean boot will disable non-essential apps and services from the Windows startup. Clean booting can potentially resolve the “not enough physical memory” in two ways. Applying this troubleshooting method will ensure there aren’t any third-party programs conflicting with VMware and free up RAM for the software.

To disable all third-party startup programs and services, check out the guidelines in our guide on how to clean boot in Windows . This will perform a clean boot whenever you restart Windows.

Try utilizing your VMware virtual machine after clean booting. If this works,

7. Set Up a New Virtual Machine

If the issue persists despite applying the resolutions above, consider setting up a new virtual machine to replace the one that needs fixing. Download the latest ISO for the virtual machine’s platform. Then you can set up the virtual machine again, as outlined on the VMware support page .
