ESX and VMWare Workstation

We can load the vmx files in both of the above softwares.

VMWare Workstation

After installing VMWare workstation 7 on SLES, we can create or open existing virtual machines. But, once you reboot the SLES and try to load existing virtual machines (which previously loaded), it throws error saying "Unable to find /dev/vmmon" module.
Do the following steps:
mv /usr/lib/vmware/modules/binary /usr/lib/vmware/modules/binary.old
vmware-modconfig --console --install-all

The reason is:
VMware comes with some pre-built binaries which somehow don't work on SLES. So we are deleting them, and by running that tool they are built again, this time for this OS.

Some Puzzles

- Producer Consumer Problem:
Scenario 1: Traditional Problem
Scenario 2: Producer should produce and puts in the shared buffer. Every consumer should consume the item before we delete it from the shared buffer.

- In race court, there are 5 tracks and 25 horses to race. We need to find the top 3 from the 25 horses. Assumption is - Horses perform in the same way during all the races and we can't record the times. You can make horses to participate any number of times. In how many races, you can find the top 3?
