Re: [Dpdk-ovs] Questions about the OpenStack Neutron with Intel Architecture document

Thank you for the reply.

I installed DPDK 1.7.0 on RedHat 6.5 with Kernel 3.7.10 and it seems
compiled successfully.

When execute the HelloWorld example, however, there was a panic error as
below:
1024 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for
that size
PANIC in rte_eal_init():
Cannot get hugepage information

The PC has Intel ATOM Processor and I binded a NIC to igb_uio module. I
think the hugepage reservation is also correctly done since I put "echo
1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages"

What should I check to solve this problem?

Thanks in advance.

Best regards

 Hi BYEONG-GI KIM

 1.      This is only needed if you are working from a machine behind a
proxy.

2.      By Accelerated OVS we mean ovs from openvswitch.org compiled and
running  with dpdk support.

You don’t have to deploy the “Accelerated OVS” compute node.

3.      We didn’t try running it on RH 6.5, let us know if you have any
issues.



Regards

Przemek

Architecture document



Hello.



I've noticed that the new version of both DPDK and corrresponding OVDK
finally has been released and the document for OpenStack Neutron with those
technologies also has been updated.



The latest guide seems changed from the past guide. Here are several
questions about those changes.



1. The guide includes "Configuring Proxies", but I'm not sure this is
essential part. If it is essential, which <PROXY> and <PROXYPORT> should be
set? And the <YOUR HOST IP ADDRESS> is also confused. Does it mean I need
to deploy another proxy PC in addition to both Compute Node and Controller
Node for OpenStack?



2. Another Sample Compute local.conf is added at 6.1.1.3, but I wonder the
difference between past one and the new one. It is described as OpenStack
Accelerated OVS Compute Node. Does it mean the new one accelerates packet
processing but the past one does not?



3. Finally, I assume that the deployment would be fit at kernel 3.1.4
version of Fedora (actually we are trying to install it on RedHat 6.5)
since the Fedora 20 is recommended. Is it right?



Best regards



Byeong-Gi KIM
