In RHEV 3.3, ksmtuned service is stopped. So, how is KSM being controlled?
Issue
Checking ksmtuned service in RHEV 3.3, I noticed it's stopped:
# service ksmtuned status
ksmtuned is stopped
But KSM is still turned on/off when needed. Low loaded hypervisor:
# cat /sys/kernel/mm/ksm/run
0
High loaded hypervisor:
# cat /sys/kernel/mm/ksm/run
1
Who is in charge of KSM now?
Environment
- Red Hat Enterprise Virtualization 3.3
NOTE: For RHV 4.0, we recommend using management interface as the preferred way for changing KSM configuration: RHV 4.0 Administration Guide, section 5.2.2.2. Optimization Settings Explained
