Hi Ray,
The VM name is csit-nested-1.6.img but nested VMs to me usually means a VM in a
VM. In this case a VM is running testpmd only.
The command below should be run while the test is running I assume?
-s

Hi Sean,
Since I guess all this is running a VM (right?), it would be good to
understand what KVM stat dump looks like. For the HP+Dell compared to
UCS/SuperMicro.
sudo ./perf stat -e 'kvm:*' -a sleep 1h
Are we using nested virtualization?
