1. Add hosts fail to configure the firewall

Do not check the "Configure filewall" checkbox

Adding host will fail because engine cannot communicate with vdsm.

Fix - disable the firewall on the host.

$ iptables -F

There is probably a better way, but I did not find it yet :-)

2. Engine fail in Host.getCapabilties 

Libvirt changed the location and format of this file. This will cause Host.getCapabilties 

to fai, and the host will become "Unassigned"

This is a new issue revealed by updating our virt-preview repo this week.

Fix - install old cpu_map.xml

$ wget https://raw.githubusercontent.com/libvirt/libvirt/18cab54c3a0bc72390f29300684396690a7ecf51/src/cpu/cpu_map.xml -O /usr/share/libvirt/cpu_map.xml

Engine should retry and succeed after that.

3. Sanlock fail to write to its pid file, connecting to storage fail

Fix - set selinux to permissive mode

$ setenforce 0

To make this persistent edit /etc/selinux/config

SELINUX=permissive

We have a bug for this.

After that you should have a working system.
