[rdo-list] [TripleO] quickstart undercloud problems.

[Nate]

Good Morning rdo-list,
im attempting to get a test openstack install up and running using RDO, and ooo quickstart on Centos 7. 

I'm following the brief instructions found here: https://www.rdoproject.org/tripleo/

I am running quickstart from the same system i'm targeting.  So i'm setting $VIRTHOST to localhost, or the local IP of the box (192.168.3.10), I've tried it both ways, which doesn't seem to make a difference.  I'm running quickstart as my local use, not the stack user. 

Initially things appear to run along nicely, the script downloads images and whatnot, it even starts up the undercloud vm as the stack user. 

[stack at fog ~]$ virsh list
 Id    Name                           State
----------------------------------------------------
 2     undercloud                     running


When quickstart gets to the point where it's attempting to determine the IP of the undercloud VM, it fails.  I did a little digging on how exactly that works, and found that the script which it runs is not getting any results. 

>From the script:
mac=$(virsh dumpxml $VMNAME | awk -F "'" '/mac address/ { print $2; exit }')

# Look up the MAC address in the ARP table.
ip=$(ip neigh | grep $mac | awk '{print $1;}')

I've tried these manually, and sure enough the mac address is not in ip neigh. 

stack at fog .quickstart]$ virsh dumpxml undercloud | awk -F "'" '/mac address/ { print $2; exit }'
00:e4:b2:54:b5:fb
[stack at fog .quickstart]$ ip neigh | grep '00:e4:b2:54:b5:fb' | awk '{print $1;}'
[stack at fog .quickstart]$ ip neigh | grep -v FAILED
192.168.3.1 dev enp13s0 lladdr 52:54:00:ab:d2:15 REACHABLE
192.168.3.251 dev enp13s0 lladdr 52:54:00:f2:90:b7 REACHABLE
[stack at fog .quickstart]$ 

I did a virsh console on the undercloud vm, and reset it, so I could watch it boot, and I see the following in the boot messages:

[FAILED] Failed to start LSB: Bring up/down networking.
See 'systemctl status network.service' for details.

I cant login to the undercloud vm, as I don't have the local username/pass.  or I'd troubleshoot that further. 


As far as I can tell the undercloud system uses standard linux bridges to setup network communication, They appear present, but as they're not configured in the same manner i've used in the past, I can't be certain if they're working properly. 

[stack at fog ~]$ brctl show
bridge name	bridge id		STP enabled	interfaces
brext		8000.525400af4796	no		brext-nic
							tap0
brovc		8000.525400180812	no		brovc-nic
							tap1
virbr0		8000.525400a3f6b5	yes		virbr0-nic
[stack at fog ~]$ ifconfig brext-nic

I've tried some other basics, like setting selinux to permissinv and re-trying (which was a long shot) and it didn't help. 

Any suggestions on what to tr next would be helpful. 

Thanks!
