@MSoares,
Apologies for my absence. I hope you are having a good start to the new year. The floating IP pool should have been created with a separate command. It seems that you possibly used the same CIDR range for both the nova network
command and the nova floating-ip-bulk-create
command.
nova network-create vmprivate --fixed-range-v4 10.11.12.0/24 --fixed-cidr 10.11.12.0/24 --bridge br100 --bridge-interface veth1
The above command you used is for the creation of the private network segment shared internally by the VM instances. To create the floating IP range, you should execute:
nova floating-ip-bulk-create <cidr>
where the CIDR is a different range from the one you used in the creation of vmprivate. It should likely be on the same network segment as the host machine which is 192.168.1.64/24. This is assuming that whomever is handing out the DHCP addresses to this host will also do so for any other VMs that show up on that segment.
Regards,
Tom
