Overhead Test Progress
Dr. Windley came up with an idea to estimate the overhead created by VMWare. The setup is fairly simple. Have a load balancer in front of a group of virtual machines. The test is simple also, you run a simple download test and note machine statistics for the parent system. Start haveing the load balancer include more and more virtual machines in the test. Watch the parent machine statistics. If VMWare had no overhead the parent machine statistics should stay the same. We should be able to tell the overhead for each virtual machine by the increase in the parent machines stats.
The big assumption here is that the overhead added by the OS itself is very small. This may or may not be true. We will need to test that to see.
If you look here you can find the list of todos that we have still to work on as well as other miscellaneous thoughts regarding the test.
Feel free to comment there on under this entry.
