Environment: MOS 9.0 ISO 459, hardware lab
1 controller + 1 compute with DPDK (In our case node-1.domain.tld) + 1 compute.
Steps to reproduce:
Run this script on freshly deployed environment. Just replace value for compute_
http://
Expected result:
Instance is available via SSH, ping.
Actual result:
Instance is not available via SSH, ping.
Additional information:
On compute with feature
ovs-vsctl get Open_vSwitch . other_config:
vcpu_pin_set from nova.conf - 6,26,7,

Confirmed on 9.0 release.
This case is quite narrow. Additional information should be added to release notes.
Main option is to step on 16.04 packages.
So it won't be fixed in 9.0 since DPDK consider to be experimental.
