nvazquez opened a new pull request #2295: CLOUDSTACK-10109: Enable dedication 
of public IPs to SSVM and CPVM
URL: https://github.com/apache/cloudstack/pull/2295
 
 
   JIRA Ticket: https://issues.apache.org/jira/browse/CLOUDSTACK-10109
   
   ### Description
   This feature allow admins to dedicate a range of public IP addresses to the 
SSVM and CPVM, such that they can be subject to specific external firewall 
rules. The option to dedicate a public IP range to the System VMs (SSVM & CPVM) 
is added to the `createVlanIpRange` API method and the UI.
   
   ### Solution
   Global setting 'system.vm.public.ip.reservation.mode.strictness' is added to 
determine if the use of the system VM reservation is strict (when true) or 
preferred (false), false by default.
   When a range has been dedicated to System VMs, CloudStack should apply IPs 
from that range to
   the public interfaces of the CPVM and the SSVM depending on global setting's 
value:
   - If the global setting is set to false: then CloudStack will use any unused 
and unreserved public IP
   addresses for system VMs only when the pool of reserved IPs has been 
exhausted
    - If the global setting is set to true: then CloudStack will fail to deploy 
the system VM when the pool
   of reserved IPs has been exhausted, citing the lack of available IPs.
