Hi Thiago,
as James said this is a known dpdk behaviour - not special to OpenVswitch.
Any other DPDK tool like l2fwd or such would have killed you just the same.
We documented it in the serverguide.
No release for 16.04 yet but you can take a look at

DPDK_OPTS='--dpdk -c 0x1 -n 4'

with Linux 4.4 (same Xenial kernel), but with DPDK 2.0 and OpenvSwitch
2.4 from Liberty Cloud Archive, it works!!
At least, the Trusty guest doesn't lose connectivity and soft reboot
works too! Precisely where Xenial
