Hi,
i had yesterday evening updated one production-server from 1.8/2.6.35 to 1.9/2.6.32.
The update process run very well and the VMs also.
But on one kvm-guest (an router with ipsec-gateway) i see this morning cpu-loads of 12-30%. This is for such an VM not normal.
I take a look inside the VM: nothing! No diskio and also not realy network-io.
Who eat the CPU-power??
top inside VM:
top on the host (pid 12658 is the one of this VM)
some more info:
The kernel inside the VM is an 2.6.32.25.
Any hints ??
Best regards
Udo
