Subject: [dpdk-dev] Crashing OVS+DPDK at the host, from inside of a KVM Guest
Date: Sun, 15 May 2016 01:08:32 -0400	[thread overview]
Message-ID: <CAJSM8J063W1nKCkUnPtOMQiT0K82wfxC-H6nXXewz6cBZYaRKA@mail.gmail.com> (raw)

Guys,

 If using OVS 2.5 with DPDK 2.2, on Ubuntu Xenial, it is possible to crash
the OVS running at the host, from inside of a KVM Guest.

 Basically, what I'm trying to do, is to run OVS+DPDK at the host, and
also, inside of a KVM Guest, with multi-queue, but it doesn't work and
crashes.

 Soon as you enable multi-queue at the guest, it crashes the OVS of the
host!

OVS+DPDK segfault at the host, after running "ovs-vsctl set Open_vSwitch .
other_config:n-dpdk-rxqs=4" within a KVM Guest:

Thanks!
Thiago
