1 Introduction
Testing OpenFOAM installations on several different Operating Systems can take its toll. But at least with virtualization, one person can handle 3, 4 or even more virtual machines at the same time or in sequence, all with a single real machine.
For the readers that don't know what machine virtualization is, here are some pages on this subject at Wikipedia:
- Page about what a Virtual machine is.
- The global description of what Virtualization is.
- Extended descriptions of selected virtualization software.
From the last link there are 2 popular and free virtualization applications for the general public:
- VirtualBox - The preferred among the open-source community, given the code is open-source.
- VMware Player - The one described in this How To page and which will be referred to from here on as VMplayer.
The choice of using VMplayer is somewhat simple: it's free, very good (if not best) performance and easy to use. (and personal preference - Wyldckat 00:11, 7 July 2012 (CEST)) Nonetheless, VirtualBox is a very good competitor, specially for testing PXE boot images. (Wyldckat 00:11, 7 July 2012 (CEST))
This wiki page is divided into the following chapters:
- How to install VMplayer
- How to create a new virtual machine
- Troubleshooting - as in don't shoot your computer, shoot only the troubles themselves
Final introductory note: this tutorial would probably be more appreciated as a video tutorial, but that exercise is left to the readers that wish to contribute!
2 How to install VMplayer
First a few links for reference:
- The official page for VMware Player: www.vmware.com/vmplayer
- Official documentation: Getting Started with VMware Player

4.1 The yield() function is not activated
Issue: A message dialogue box appears saying:
The yield() function is not activated
And doesn't allow running the machine.
Note: This is happens on Linux with kernel versions greater or equal to 2.6.31.
Solution: To fix this until next boot, run as root:
echo "1">/proc/sys/kernel/sched_compat_yield sysctl -w kernel.sched_compat_yield="1"
For a permanent solution, run as root as well:
echo -e "\n\n#This is needed for Virtual Machines to run at full power\!\nkernel.sched_compat_yield = 1" >> /etc/sysctl.conf
4.2 Unable to operate the VMplayer window
Issue: Error and warning windows sometimes pop to the wrong side of the window, namely to the back of the VMplayer window!
Note: This is more common on Linux.
Solution: The main window is sometimes still usable, in the sense that it can still be moved out of the way, to reveal the small error/warning dialogue in the back of the main window.
4.3 /dev/vmmon does not exist
Issue: A dialogue appears with the message:
/dev/vmmon does not exist
Note: This is more common on Linux.
Solution: run as root:
/etc/init.d/vmware stop /etc/init.d/vmware start
