dnsmasq internal details for processing host file entries
1) dnsmasq reads the host file from EOF.
2) So it first picks up stateless IPv6 entry,
fa:16:3e:8f:9d:65,set:aabc7d33-4874-429e-9637-436e4232d2cd
3) But dnsmasq doesn't have sufficient checks to skip this entry and
pick next entry, to process dhcp IPv4 request.
4) So dnsmasq uses this entry to process dhcp IPv4 request.
5) As there is no ip in this entry, dnsmasq logs "no address available"
and fails to send DHCPOFFER message.
As we rely on internal details of dnsmasq to understand and fix the
issue, Ihar sent a mail to dnsmasq-discuss mailing list
http://lists.thekelleys.org.uk/pipermail/dnsmasq-discuss/2015q2/
009650.html

so that entry for stateless IPv6 comes first,

If the graphical consoles VNC and SPICE are disabled, the

VNC and SPICE are usually disabled on IBM z systems platforms
