[dpdk-users] Issue in installing DPDK on VM

[hou guanghua]

I had met the same problem with your before. In the GUI dialog (after run virt-manager), you can set the attributes of cpu, such as sse4_1,sse4_2. 
BTW, KVM is used in my enviroment.

Regards,
Guanghua

主题: [dpdk-users] Issue in installing DPDK on VM

Hi,

We are installing dpdk2.2.0 on a VM having linux kernel 3.13.0-77 and we
are getting the following error.

When we searched online, we got similar issue in
http://rumpkernel-users.narkive.com/qJxwkczX/rump-kernel-for-dpdk.
They mentioned setting the CPU flags ssse3, avx and aes to resolve this
issue. These flags are enabled on the physical machine but not on the VM
even though they both have the same kernel and OS (ubuntu14.04). We have
used virt-manager with kvm-qemu as the hypervisor to host the VM. How can
we enable these flags in the VM. Or are we missing out on some other
parameter that need to be set?

Thanks,
Mitali
