I've installed VMWare Player 6.0.1 build - 1379776 on a Red Hat Enterprise linux Server release 6.1 Beta ( Santiago ). When I attempt to start my virtual machine, I get the following the error:

  Could not open /dev/vmmon: No such file or directory.
  Please make sure that the kernel module `vmmon' is loaded.

uname -r


When I install vmmon I get the following error:

sudo modprobe vmmon

FATAL: Error inserting vmmon (/lib/modules/2.6.32-122.el6.x86_64/misc/vmmon.ko):    Invalid module format 

My 2nd question is:

When I install it with vmware-modconfig –console –install-all I get the following error. How can I install all these packages?

Gtk-Message: Failed to load module "pk-gtk-module": libpk-gtk-module.so: cannot open    shared object file: No such file or directory
Gtk-Message: Failed to load module "canberra-gtk-module": libcanberra-gtk-module.so: cannot open shared object file: No such file or directory
Logging to /tmp/vmware-root/vmware-modconfig-9282.log
Icon name must be set.

VMWare player and workstation comes with Linux drivers, You need to install to get /dev/vmmon.

You can find linux.iso on installed directory. Run vmware-config.pl instead of rpm installation.

It will compile the two modules vmmon and vmnet which are require to run a virtual machine. I rather use tar.gz or tar.bz2 files instead of RPM files.


I got the same problem. then disabling secure boot worked for me. try the following

disable UEFI Secure Boot

restart+Shift key Go to Boot Manager and disable the option Secure Boot.

Change the UEFI boot order according to the medium you want to boot the computer
