VMFS and Test Data for the VMs
So I have learned a couple of things about VMFS. First it is a propriatary file system that is best suited for very large files, such as isos and disk images. This makes sense because its primary purpose is to host disk images that are use by virtual machines.
Second it looks like it should be possible to mount a VMFS drive under the host system. However, I have not figured out how to do that quit yet. I have discovered though that I can create a disk image that can be loaded into multiple virtual machines. What this means is that we can create a disk image of the data we want to use for benchmarks and then just have each of the virtual machines load it for use. One thing to note however is that you have to make all of the machines discard any changes they would actually make to the drive. If they don't then only one machine can power up with that drive at a time, I think it must do some sort of locking.
My current todo is
- Create less beafy virtual machine
- Get example websites and files (I've contacted Steve about this)
- Run some initial tests and benchmarks that will help me figure out how to run tests and benchmarks
