Regarding the screenshots, did you clear the cache? Is this FF or Chrome?

I'm trying to add a host running Fedora 28 to engine 4.2, and installation

Can you please send output of "rpm -qa|grep otopi" ? Please note that otopi and ovirt-host-deploy are installed on the 4.2 engine host and executed with ssh on the fedora 28 host. So you'll need otopi and ovirt-host-deploy from master installed on the 4.2 engine host.

On the 4.2 engine host I'm using latest 4.2 release and repos.

Tried again with engine master (2e3a05ffc83611a2cb18c2ca7268be2d489834f9)
on CentOS 7.5 (1804).

$ rpm -qa | egrep 'otopi|ovit-host'
otopi-common-1.8.0-0.0.master.20180614102257.git6c66781.el7.noarch
python2-otopi-1.8.0-0.0.master.20180614102257.git6c66781.el7.noarch

$ rpm -qa | egrep 'ovirt-release'
ovirt-release-master-4.3.0-0.1.master.20180620000053.git025660e.el7.noarch

Building and installing engine was great pain. Developer documentation is
in the same poor state it was 5 years ago.  Thanks Daniel for the help!

Adding Fedora 28 host fails with (in host deploy log):

AttributeError: 'str' object has no attribute 'decode'
2018-06-21 02:12:18,864+0300 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Initializing': 'str' object has no attribute 'decode'

After fixing this we fail with (in host deploy log):

TypeError: a bytes-like object is required, not 'str'
2018-06-21 02:21:50,148+0300 ERROR otopi.context context._executeMethod:152 Failed to execute stage 'Setup validation': a bytes-like object is required, not 'str'

With this patch we reach the next failure in otopi, fixed in

Next failure is in TASK [ovirt-provider-ovn-driver : Install ovirt-provider-ovn-driver]:
The conditional check 'ovn_central | ipaddr' failed. The error was: The ipaddr filter requires python-netaddr be installed on the ansible controller

After installing python-netaddr on the engine host, we passed
this step.

I don't know why this ansible playbook is running, I answered NO
when engine-setup asked about OVN.

I'm not sure where the dependency on python-netaddr should be.

Next failure is in TASK [ovirt-host-deploy-firewalld : Enable SSH port] 
unsupported version of firewalld, requires >= 0.2.11

# rpm -q firewalld
firewalld-0.5.2-2.fc28.noarch

Obviously the complain is incorrect, "0.5.2" > "0.2.11".

I worked around this by disabling firewall configuration when adding
a host.

The host was added but was not reachable.

To fix this, I disabled the firewall on the host using:
iptables -F

The next issue is missing ovirtmgmt bridge on the host, using setup networks
fixed the issue - and the host became UP.

I tried to add storage, and found that:

- engine "New Domain" dialog is very broken now. See attached screenshots.

- block storage is broken because of lvm bug, caused by GCC bug

- file storage is broken because sanlock fail to write to its lockfile - selinux again.

To work around this, I switch to permissive mode:
setenforce 0

At this point I could upload and download images from engine UI!

So in summary, to add Fedora 28 host:
- patch ovirt-host-deploy: https://gerrit.ovirt.org/#/c/92437/ and install on engine host
- patch otopi: https://gerrit.ovirt.org/#/c/92435/ and install on engine host
- install python-netaddr on engine host
  - need to file a bug
- disable firewall setup in engine "Add host" dialog
  - need to file a bug
- disable firewall on the host
- use setup networks to add ovirtmgmt network to the host
- forget about block storage for now
- change selinux to permissive mode
- we need a tracker bug for fedora 28 issues
