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 examples in a native platform.
But when I try to move it to virtual machine, it gives me the following
error:

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

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

Do you have any idea?

Thank you,

Jinho

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

You should try "-cpu host" option of Qemu/KVM in order to have the full 
instruction set of your host.

Please confirm it's working.

Hi, I'm new to DPDK and Im trying to compile on a x86 Ubuntu 14.04 VM(KVM).
And I'm getting this error:

"error: CPU you selected does not support x86-64 instruction set"

I've seen in the Archive that Jinho had this same issue last year, I'd be
glad to know how it was resolved.

Thanks
Alex.

This error can also be cause by the VM's CPU definition not being defined. The following xml snippet of code is from my DPDK VM's definition.
