Whether you've switched on DHCP-server on the subnet which VM belongs to? If yes - check logs of DHCP-server (dnsmasq) on the node where it resides - whether it receives DHCP requests and whether it sends answers or why it rejects requests. If DHCP-server don't receives requests or if it sends answers and VM don't receives them - check using tcpdump entire chain of ports between VM and DHCP server and find where it drops DHCP exchange.
