Upgraded My Fedora to 26 today and found my VMplaye-12.5.7 can not be started on Fedora 26. So I reinstalled vmplayer with version 14. VMplayer14 started properly, but when I started a VM, an error occurred as

” The virtual machine is unable to reserve memory“.

I tried several times, it reported either

” The virtual machine is unable to reserve memory” or “Not enough physical memory is available to power on this virtual machine”.

The vm’s memory is 1G, and I still have more than 4G free memory at the moment, so it can’t be the shortage of the memory that causes the problem. I searched for a while and found the solution here: https://communities.vmware.com/thread/573966

What is needed is the vmware-host-module patch from GitHub. Download the correct branch which corresponds to the vmware version, that is player-14.0.0 in my case, and do the following operations :

tar -cf vmmon.tar vmmon-only/

tar -cf vmnet.tar vmnet-only/

cp *.tar /usr/lib/vmware/modules/source/

Then remove the .ko files from /lib/modules/$(uname -r)/misc.

now do

vmware-modconfig –install-all

Then I rebooted the system and tried to run VMplayer again, everything went ok now.
