Description Zhouping Liu 2013-10-31 09:27:40 UTC 
Description of problem:

ksm.service and ksmtuned.service, which are provided by qemu-kvm-common package, can't be started through systemctl:
[root@hp-dl585g7-01 git_test]# systemctl status ksm.service
ksm.service
   Loaded: not-found (Reason: No such file or directory)
   Active: inactive (dead)

and I found the reason is ksm.service and ksmtuned.service were located in /usr/lib64/systemd/system, not in /lib/systemd/system/ :

[root@hp-dl585g7-01 git_test]# rpm -ql qemu-kvm-common | grep ksm
/etc/ksmtuned.conf
/etc/sysconfig/ksm
/usr/lib64/systemd/ksmctl
/usr/lib64/systemd/system/ksm.service
/usr/lib64/systemd/system/ksmtuned.service
/usr/sbin/ksmtuned


Version-Release number of selected component (if applicable):
[root@hp-dl585g7-01 git_test]# rpm -q qemu-kvm-common
qemu-kvm-common-1.5.3-8.el7.x86_64

How reproducible:
100%
