Hi,

I am having trouble to compile the dpdk in a = virtual machine. I am using KVM as a hypervisor, and guest os is ubuntu 12.= 10, kernel 3.5.0, x86_64. I have been using dpdk for a week and run the exa= mples in a native platform. But when I try to move it to virtual machine, i= t gives me the following error:

/home/guest/dpdk-1.2.3r1/lib/librte_eal/linuxapp/eal/eal.c:1:0: e= rror: CPU you selected does not support x86-64 instruction set

I am sure that I have installed 64 bit version as it shows in "u= name -a". Also, /proc/cpuinfo shows "model name: QEMU Virtual CPU= version (cpu64-rhe16)".

Do you have any idea?

Thank you,

I figured out just now. It was because gcc version. = I used to use 4.4,=20 but in the guest virtual machine, I used 4.7 which may have additional=20 functions to check strictly. - Jinho
