Any help?

Answer 1

Do you have /usr/sbin/dhcpdon the system? If not, you either need to point Eucalyptus to the right location of your DHCP daemon using VNET_DHCPDAEMON parameter in the /etc/eucalyptus/eucalyptus.conf file or you need to install a DHCP daemon and ensure that the parameter above is pointing to it.

Answer 2

Yes, I have /usr/sbin/dhcpd on the system. and this is file configure of eucalyptus.

There may be a port conflict with dnsmasq preventing dhcpd from starting. Check if the "default" network is active on the node controller:

# virsh net-list

if it is then you can use:

# virsh net-destroy default

to destroy the default network and stop the associated dnsmasq process allowing dhcpd to run.
