May need to setup huge pages on kernel boot line (this is example, you may need to adjust):
The huge page configuration can be added to the default configuration file /etc/default/grub by adding to the GRUB_CMDLINE_LINUX and the grub configuration file regenerated to get an updated configuration file for Linux boot. # vim /etc/default/grub // edit file . . . GRUB_CMDLINE_LINUX_DEFAULT="... default_hugepagesz=1GB hugepagesz=1GB hugepages=4 hugepagesize=2m hugepages=2048 ..." . . . This example sets up huge pages for both 1 GB pages for 4 GB of 1 GB hugepage memory and 2 MB pages for 4 GB of 2 MB hugepage memory. After boot the number of 1 GB pages cannot be changed, but the number of 2 MB pages can be changed. After editing configuration file /etc/default/grub , the new grub.cfg boot file needs to be regenerated: # update-grub And reboot. After reboot memory managers need to be setup: If /dev/hugepages does not exist: # mkdir /dev/hugepages # mount -t hugetlbfs nodev /dev/hugepages # mkdir /dev/hugepages_2mb # mount -t hugetlbfs nodev /dev/hugepages_2mb -o pagesize=2MB Mike -----Original Message----- From: dev [mailto:dev-boun...@dpdk.org] On Behalf Of Abhijeet Karve Sent: Monday, November 30, 2015 10:14 PM To: dev at dpdk.org Cc: bhavya.addep at gmail.com Subject: [dpdk-dev] DPDK OVS on Ubuntu 14.04 Dear All, We are trying to install DPDK OVS on top of the openstack juno in Ubuntu 14.04 single server.

Can anyone please help us in getting the things if we are missing any and causing ovs-vswitchd to stuck while starting? Also, when we create vm in openstack with DPDK OVS, dpdkvhost-user type interfaces are getting created automatically. If this interfaces are getting mapped with regular br-int bridge rather than DPDK bridge br0 then is this mean that we have successfully enabled DPDK with netdev datapath? We really appreciate for all the advice if you have.
