Hi Roman,
In my experience when using OVS the cloud0 bridge sometimes has to be
configured manually. Check my blog post from last year on this, it has some
examples on the cloud0 bridge setup:

I'm not sure if it is actually related to cloud0...
I'm troubleshooting this way now:
Copying one of /var/cache/cloud/processed/ip_associations.json.* to
/var/cache/cloud/ip_associations.json inside VPC
Running from the host
/usr/share/cloudstack-common/scripts/network/domr/router_proxy.sh
update_config.py 169.254.1.227 ip_associations.json
I'm immediately getting the error (I added few print lines and trying to
figure out where exactly in /opt/cloud/bin/* interface becomes ethNone)

Simon,
Thanks for your help. I posted all my configs and print screens with
labels (URL - first line in pastebin) here:

Interface and bridge configs would be helpful as well.

Can you provide your /etc/cloudstack/agent/agent.properties file on the
host?
Can you also screenshot your traffic label configuration for each network
type?

Simon,
I saw this but I thought that "cloud0" is something I have no control over?
(Some internal cloudstack bridge that it creates and manages completely
automatically)
Do you have any idea on how this can be fixed?
Thanks
Roman

Roman,
Take a look at these logs:
1.

You may need to change your underlying interface name to match one of the
supported types above. I'd fix that before you troubleshoot further and see if
it has any affect.

Simon,
Yes, I have traffic labels setup for my networks (2 guest networks with
different tags and 1 public). Advanced network setup / Centos-7.x on
hypervisors.
I enabled debug on hypervisor and tried to restart router VM via Cloudstack
GUI. Since its config overwritten I presume something happens exactly at this
stage..
Here it is: https://pastebin.com/6VRHyRnJ
[https://pastebin.com/i/facebook.png]<https://pastebin.com/6VRHyRnJ>
2017-06-16 14:54:57,513 DEBUG [cloud.agent.Agent]
(agentRequest-Handler-1:null) - Pastebin.com<https://pastebin.com/6VRHyRnJ>
pastebin.com
I really can't see anything wrong in there. It correctly associates VPC
public interface with my bridge for public network (brenp6s0-904)
Thanks
Roman

Roman,
Do you have a traffic label setup for your public network?
Can you put the host in debug mode:

- Si

Subject: ethNone problem with VPC
Hi Everyone,
Does anyone encounter "ethNone" interfaces in VPC routers?
I'm running cloudstack 4.9.2.0 with KVM hypervisor and every time I create
VPC router it fails to do proper setup, with errors:
====
Traceback (most recent call last):
File "/opt/cloud/bin/configure.py", line 931, in main
config.address().process()
File "/opt/cloud/bin/cs/CsAddress.py", line 103, in process
ip = CsIP(dev, self.config)
File "/opt/cloud/bin/cs/CsAddress.py", line 256, in __init__
self.dnum = hex(int(dev[3:]))
ValueError: invalid literal for int() with base 10: 'None'
====
Only local link IP (eth0) is up.
/etc/cloudstack/ips.json inside my VPC routers always look like this (I
guess this explains above):
====
{
"eth0": [
{
"add": true,
"broadcast": "169.254.255.255",
"cidr": "169.254.1.238/16",
"device": "eth0",
.....
...
}
],
"ethNone": [
{
"add": true,
"broadcast": "X.Y.Z.255",
"cidr": "Y.Y.Z.43/24",
"device": "ethNone",
.....
....
}
],
"id": "ips"
}
====
X.Y.Z.0/24 is my public network
If I manually edit /etc/cloudstack/ips.json (change ethNone to eth1) - then
restart VPC router manually (via virsh) - everything works, interfaces/iptables
are up..
Until next time I do anything with this VPC from GUI - then ethNone
reappears and everything is broken again..
Appreciate if anyone has any thoughts.
Thanks
Roman
