| |
| | Installation
| |
| || Install F12 on the host, then install multiple virtual machines of the same type. To speed up this process you can install a single virtual machine and use virt-clone to make additional virtual machines for testing. For KSM to properly function you need to ensure you have the latest qemu installed (version should be 0.10.92-4.fc12).
| |
| If there are any installation errors or dependency problems, these are serious bugs and should be reported.
| |
| |-
| |
| | Start up
| |
| || First start the ksm service. Start up just one of the virtual machines. Take a look at /sys/kernel/mm/ksm/pages_shared. There should be a non zero value here, the actual value is less important, but take note of it. Next start up additional virtual machines and check /sys/kernel/mm/ksm/pages_shared again. The value should increase over a single running guest.
| |
| |- | |
| | ksmtuned | |
| || Try shut down all of the virtual machines and start the ksmtuned service. Once the service has started, restart the virtual machines one at a time. How does the ksm performance compare to ksm without ksmtuned? If there is a drastic difference for the better or the worse, please mention it in IRC.

| |
| * after turn off of all (two) KVM guests virt-manager frozen, known bug
| |
| * ksm and ksmtuned are quite the same wrt shared pages and memory consumption... tested on Rawhide host with two Rawhide guests (one cloned from the other)
| |
| ** KSM - 1620 MB / ~20.000 shared pages
| |
| ** KSMtuned - 1600 / ~15.000 shared pages (surprisingly)
| |
| * it is 2 GB system and some 500 MB of operating memory was still free after running two guests, shame I didn't know that the page merging is more often when the memory gets tighter...
