Root cause: Default cpu config when the VM has be been started by qemu does
not support SSE.

I have resolved this issue. Here the resolution which I used. Might be
helpful for others

Method 1
After Configuring VM by GUI based Virtual Machine Manager, go to the CPU
config & make SSE as "Required"

Method 2
pass -cpu options to qemu-system-x86_64 with your cpu type [Nehalem] in my
case.
-cpu
Nehalem,+rdtscp,+x2apic,+dca,+pdcm,+xtpr,+tm2,+est,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme
