From Console logs of the vm, eth0 interface is not configured correctly as it
have IPv4LL address instead:-
Nov 25 08:44:45 cirros daemon.info dhcpcd[316]: eth0: using IPv4LL address
169.254.203.238
From DHCP aggent logs, there were DHCPDISCOVER/DHCPOFFER but no
DHCPREQUEST/DHCPACK

For in other failures it was seen differently like dhcp took time to
configure and in meanwhile metadata failed(failed 20/20: up 56.38. request
failed):-
