COMPONENT NAME

CLOUDSTACK VERSION

4.14

CONFIGURATION

ACS 4.14, Ubuntu 18, KVM, Advanced Networking, Local Primary Storage.

OS / ENVIRONMENT

SUMMARY

I did configure ip reservation strictness set to true, but forgot to create an IP range for system vms.
I create a new cluster, and it starts, System VMs are generated with Public IPs despite the setting.
When I attempt to restart the System VMs later on, I get Insufficient capacity exception.

STEPS TO REPRODUCE

configure system.vm.public.ip.reservation.mode.strictness =true
create a zone,
create networks
create traffic types
ip ranges (do not create any range for system IPs)
create pod, cluster
enable zone
enable networks
add hosts,

I am using this ansible playbook: https://pastebin.com/z40KKhEt

EXPECTED RESULTS

cluster creation should fail, or SVMs should report insuficient capacity

ACTUAL RESULTS

cluster was created and SVMs assigned public IPs despite setting
when attempting to recreate the SVMs, insuficient capacity is reported. 

[rvalle]

is it possible that modifying system.vm.public.ip.reservation.mode.strictness=true requires a platform restart?

[rvalle]

OK, after manually setting it on the UI I can see that the setting requires the cluster to restart.
