connection to host broken during packstack installation

[Manuel Sopena Ballesteros]

I try to install openstack newton using packstack and the following command:

packstack --allinone --provision-demo=n --os-neutron-ovs-bridge-mappings=extnet:br-ex --os-neutron-ovs-bridge-interfaces=br-ex:enp1s0f1 --os-neutron-ml2-type-drivers=vxlan,flat --cinder-volumes-size=8000G --ntp-servers=0.au.pool.ntp.org

I only have 1 NIC on host (enp1s0f1)

Installation goes through but before it finish I loose connection to host.

I can see the following ifcfg-br-ex content:

ONBOOT=yes
PEERDNS=no
NM_CONTROLLED=no
NOZEROCONF=yes
DEVICE=br-ex
NAME=br-ex
DEVICETYPE=ovs
OVSBOOTPROTO=dhcp
TYPE=OVSBridge

I can add static IP to br-ex and reinstall but instances won't be able to connect to host gateway and beyond

thank you

I haven't been able to reproduce the exact issue with the latest code, but I found a similar situation where, after a reboot, br-ex did not get an IP address. After some tests, I think it is related to using DHCP in br-ex, because it works fine with static IPs.

Could you try running Packstack again on a system with a static IP and see if you can reproduce the disconnections?
