When disabling IP tables the above works Actual results: DHCP requests are blocked by host's iptables Expected results: DHCP requested should be passed and IP assigned to VM Additional info:
Our plan presently is to support Quantum only when network namespaces are enabled. There are too many caveats and configurations that do not work when netns is disabled, such that it is not a supportable configuration for our customers. Because of that, I am closing this bug as WONTFIX. The workaround should be to enable network namespaces and use a kernel/userspace that supports netns.
