VMware Player error on Linux

Recently I decided I needed to spend more time on Linux. I am using a Dell Latitude 7480 with 16GB RAM and a 500GB SSD. I installed Linux then I tried to install the latest version of VMware player 16.0.2.

VMware Player Installing

The installation would say it was “successful”, but there would be a bunch of errors.

When I started VMware Player, it behaved as expected—prompting for licence agreements etc.

I created a virtual machine and tried to start it. I then received the following error. “Could not open /dev/-vmmon: No such file or directory. Please make sure that the kernel module ‘vmmon’ is loaded.”

This error would make me curse for hours! I followed various guides telling me to install different packages, gcc, essentials, etc. Then, I saw posts telling me I was using the wrong Linux. Initially, I had installed Ubuntu 21.04. Instead I tried Ubuntu 20.04 LTS, with similar results. It appeared something was wrong with VMware and the Kernal.

After much testing without success, I managed to get lucky. I was in the laptop UEFI/BIOS settings and thought to change “Secure Boot -> Secure Boot Enable” and set it to “Disabled” I was grasping at straws. However, after rebooting, I could now start virtual machines without error! VMware Player is currently working for me. I hope other people who experience this error find this blog post before burning too much time.

    I’ve recently been messing with Vagrant in Linux and see that there’s a need to disable the KVM kernel module to allow other hypervisors (such as VirtualBox, that I was using). Details here: https://ostechnix.com/how-to-install-vagrant-on-linux/#troubleshooting-vagrant under the “Vagrant Troubleshooting” heading. e.g. for Intel x86_64:
    # echo ‘blacklist kvm-intel’ >> /etc/modprobe.d/blacklist.conf
    and reboot…
