I used the same arguments that vpp dpdk-config is using, and passed it to the dpdk-testpmd, with hugepages set to 2M.

Strange. I usually unmount and then mount the hugepages mount point before using it, just to be sure. Maybe the two different mount points confuse DPDK somehow. By the way, if you have dpdk-testpmd, what is its output? Does it return the same error message? - Shmuel Hazan mailto:s...@tkos.co.il | tel:+972-523-746-435 | http://tkos.co.il On 26 May 2020 20:57:30 "Manoj Iyer" <manoj.i...@arm.com> wrote: ________________________________ From: Benoit Ganne (bganne) <bga...@cisco.com> Sent: Tuesday, May 26, 2020 12:31 PM To: Manoj Iyer <manoj.i...@arm.com>; vpp-dev@lists.fd.io <vpp-dev@lists.fd.io> Cc: Rodney Schmidt <rodney.schm...@arm.com>; Kshitij Sudan <kshitij.su...@arm.com> Subject: RE: [vpp-dev] VPP fails to start - error message EAL: FATAL: Cannot get hugepage information. > I removed the plugin and it starts the service!

Which interfaces are you going to use to rx/tx packets? VPP natively supports some Intel, Mellanox and virtual NICs but otherwise you'll need to use DPDK. And for that you'll need the DPDK plugin. That is exactly the problem now. I need to use DPDK, and how do I get the plugin to work? Do we know the root cause of the issue why the plugin fails? Any pointers on this would be really appreciated. Thanks Manoj Iyer IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
