Hello All,
I am using centos6.5 x64 on a server with 48 G RAM and 8
Cores.Managed by Ovirt
There is only one running VM with RAM 34 G and with 6 VCPU (pinned to
proper numa nodes)

Any idea why ksmd is not coming to normal CPU usage ,on a different
server ksmd was disabled and for testing when i enabled it initially
CPU usage was high but later settled down to 3% ,in that host i have 4
VMs running.
Before turning off ksmd can any one help me find out why ksmd is
behaving like this.Initially it had 2 virtual machines,because of high
CPU utilization of this guest other is migrated to another host.
Thanks
