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 Thanks to *Masaru OKI & * *Christian Ehrhardt for the info*
