How to fix a VCMI Error

VMCI or Virtual Machine Communication Interface is one of the many features offered by VMware virtualization software. It speeds up the communication between a virtual machine and the host operating system, as well as between two or more virtual machines on the same host.

Furthermore, it allows communication between virtual machines and the host operating system without risking network communication overhead. For certain types of communication, this can improve performance and reduce latency.

However, in some scenarios, we may come across VMCI errors. To begin with, our experts suggest checking if the VMCI device is enabled in the Virtual machine’s settings.

If you have been unfortunate to come across the following error message, you have come to the right place.

VMware Workstation Error: Unable to Open Kernel Device ‘\\.\VMCIDev\VMX

Let’s take a look at how to solve this error:

1. First, we have to locate the Virtual machine’s folder.
2. Then, find the VMX file and open it with a text editor.
3. Next, look for the line that begins with vmci0.present and change its value to FALSE.
4. Finally, save and exit the file before restarting the computer.

If the above fix doesn’t seem to resolve the issue, our experts suggest uninstalling the VMWare workstation program and reinstalling it. If you need further help, drop us a line in the comments.
