Red Hat Bugzilla – Bug 827942
every upgrade enables 'ksmd'
Last modified: 2013-01-09 07:02:55 EST
Description of problem:
qemu-common scripts contain
| /bin/systemctl enable ksm.service
| /bin/systemctl enable ksmtuned.service
'ksm' is an expensive service ('expensive' in terms of money: power consumption of an idle machine increases from 36 watt to 40 watt after enabling ksm) without much gain (I have a KVM server with 6 windoze guests but do not see that physical memory usage is reduced after enabling ksm).
Therefore, please make usage of ksm optional and do not enable it at every upgrade.
