Hi I have a class C network and I am trying to change the start address of my dhcp range, i tried :

nova-manage fixed reserve --address x.x.x.x

but it doesn't seem to work, instance still spawn with ip at the beginning of the network. I also tried to change it with dnsmaq but it didn't work either (according to the OS admin guide this is expected) I am using legacy nova-network in flatDHCP mode.

Thanks
