Resovled: Not Enough Physical Memory in VMware [5 Fixes]

Why not enough physical memory in VMware Workstation

VMware Workstation is a Type 2 hypervisor that is used to create and manage virtual machines. Although it provides convenience to users, sometimes there are some issues may occur in VMware Workstation. Some users report that they have encountered VMware not enough physical memory error when they power on VM. The error message was like: Not enough physical memory is available to power this virtual machine with its configured settings.

The most direct cause of the error is probably not allocating proper memory. For example, you have allocated too much memory for the VM, while some other applications and VMs are also using a lot of memory on your computer. In addition to this, there are some other reasons may cause this insufficient physical memory error:

• Non-Optimal VMware Settings
• Non-Availability of Administrator Rights
• Conflicting Windows Update
• Outdated VMware Version
• Conflicting Applications
• Wrong Configuration of VMware

This article will introduce 5 tips to fix not enough memory in VMware error one by one.

How to solve VMware not enough physical memory error (5 fixes)

The error of not having enough physical memory in VMware may be due to your system's RAM memory being too low. So how much ram to give to virtual machine? Besides this, sometimes this error can still occur even if there is enough memory. Please continue to read the following part that describes the efficient fixes.

Fix 1. Allocate proper RAM

Some users are wondering “how much memory should I allocate to virtual machine”. Generally speaking, the rule is “2.5 x Amount of RAM" = amount of virtual memory you need. So if you have 500MB of RAM you need 1.25GB of free hard drive space for VM.

If your virtual machine is asking for too much memory, you could decrease the memory size of this VM and increase physical memory. Open File Explorer and right click This PC to select Properties.

In order to make sure your system has enough RAM to run VMware, you could also shut down unnecessary applications or disable startup programs.

Fix 2. Adjust VMware Memory Settings

According to their preference, some users will tweak the system using VMware Settings. However, during this process, users sometimes set VMware to non-optimal settings which will eventually cause VMware to show the error of not having enough physical memory.

1. Power-off the virtual machine on VMware Workstation.

2. Click on Edit >> Preferences.

3. From the left pane, select Memory. It’s more recommended to choose the third option.

Fit all virtual machine memory into reserved host RAM: This option should be chosen when you have a large memory.
Allow most virtual machine memory to be swapped: This option should be chosen when you have a slightly larger memory and you want the virtual machine to run more smoothly.
Allow some virtual machine memory to be swapped: This option should be chosen when you do not have much memory.

4. Click OK.

Fix 3. Run as Administrator

VMware needs administrator access to different files/services/resources of the host environment to complete its operation. If you are using VMware without administrative privilege, your VMware may show the error under discussion.

1. Shut down the VMware Workstation.

2. Press Windows key and type VMware Workstation.

3. Right-click on VMware Workstation and select Open File Location.

4. Right-click the VMware Workstation icon and select Properties.

5. Click on the Compatibility and select the checkbox of “Run this program as administrator”.

6. Click OK.

Fix 4. Uninstall Windows update

Windows Update is designed to improve features and patch loopholes. However, one of the major reasons that can cause this error is a recent Windows update that restricts users from starting the virtual machine. Therefore, you can solve this problem by uninstalling it.

1. Press Windows key and select the Settings >> Update & Security.

2. In the left pane, click Windows Update >> View update history.

3. Click Uninstall Updates to uninstall the latest updates from your system.

Fix 5. Modify the config.ini file

If none of the above methods has worked so far, you can try to add or modify a configuration file to limit VMware Workstation to use a certain percentage of the host's available memory. This will ensure that the virtual machine only uses 75% of the host's memory.

1. Locate the path of config.ini file.

2. Open the config.ini file, and add the following line to the end of the file.

3. Save the file and restart your system.

4. Reboot your host computer and virtual machine.

These methods can help you solve the issue of “not enough physical memory is available to power on this virtual machine with its configured settings” in VMware Workstation. At the same time, this error may make users lose access to their data, which poses a huge security threat to your virtual machine, or even lead to irreversible data loss. So it’s necessary to backup VMware virtual machines.
