HI Wei, I have not tested with qemu-kvm-ev. I am willing to try but what effect will it have on my existing setup when I install qemu-kvm-ev in my existing qemu-kvm. Should I have to remove qemu-kvm and install qemu-kvm-ev? In the previous test I was able to start the machine with Fixed Offering but the option for Scaling the VM in UI was not present while the VM was in running state but was available when the VM was in shutdown state only.
Thank You.
