[dpdk-dev] Unable to start DPDK+Netshard

[harshavardhan Reddy]

Edit the /etc/default/grub file, and add the following to the
GRUB_CMDLINE_LINUX entry:
GRUB_CMDLINE_LINUX="hugepagesz=1G hugepages=
default_hugepagesz=1G"
There only you can mention cpu isolation also.

After modifying run

grub2-mkconfig -o /boot/grub2/grub.cfg

reboot system

vhost-user1 type=dpdkvhostuser
$OVS_DIR/utilities/ovs-vsctl add-port ovsbr0 vhost-user2 -- set Interface
vhost-user2 type=dpdkvhostuser

In my VM's xml file I have done the below "highlighted "changes as well

sudo virsh dumpxml AP1

[dpdk-dev] Intel DPDK support for ntop DPI

[harshavardhan Reddy]

Hi All,

Is ntop DPI integration available for Intel DPDK..?

I could see only Propretory qosmos ixEngine integrated with DPDK and
Windriver with its own DPI.

But not found any info about nDPI integration with DPDK.


Thank You,

Regards,
HVR
