Vlad,

You should provide a little bit more than that. At least the following:
1. Hypervisor type and version.
2. Network setup (physical and logical). In brief. I guess you use KVM, so do you have openvswitch or do you use linux bridge?
3. Cloudstack version and type of zone you are trying to configure (basic, advanced) ?
4. Agent conf file would be also great

Hi Vladislav,
As per the bug you mentioned, its fixed in 4.2.
Which version of cloudstack are you using? If its not working in 4.2+, can
you reopen the bug?

Vlad,

Check the settings for your network traffic labels. I assume mgmtbr
might be defined there..
