Cloudstack 4.11 - Ubuntu 16.04 Agent UFW firewall issues


Hello Devs,

When we deployed cloudstack 4.11.0 into production, we found that the UFW rules for the KVM host overrides the firewall rules set by the user in cloudstack. This prevented network access to the VMs on most ports.

We followed the guide on this page for the advanced zone – ubuntu.
http://docs.cloudstack.apache.org/projects/cloudstack-installation/en/4.11/hypervisor/kvm.html

Disabling UFW on the KVM host fixed the issue but obviously not a great solution ☹

Is there any logging that would help? I have a spare server in the production cluster that I can test the issue on.
Kind regards,
Glen Baars
