When I operate a DPDK based application, the EAL always reports the followi=
ng:
EAL: WARNING: Address Space Layout Randomization (ASLR) is enabled in the k=
ernel.
EAL:      This may cause issues with mapping memory into secondary processe=
s.

Our application is DPDK client/server based and runs properly.

My questions are:

*         Is this warning of any importance?

*         Should ASLR be disabled?

*         Does ASLR affect DPDK performance?

Issue Update: 7. Re: How do you setup a VM in Promiscuous Mode using PCI

      Pass-Through (SR-IOV)? (Qiu, Michael)

The problem I had was due to the fact that RMRR was used by the HOST for th=
e HP 10G NIC card; which prevented me from performing a PCI Pass-Through.
HP provided a BIOS and NIC Firmware update to resolve this.  It is to note =
that an Intel NIC having an 82599 Ethernet Controller did not generate the =
RMRR issue!
