             Summary: New VR after network restart w. cleanup is missing DNS and DHCP entries
                 Key: CLOUDSTACK-10167
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-10167
             Project: CloudStack
          Issue Type: Bug
      Security Level: Public (Anyone can view this level - this is the default.)
    Affects Versions: 4.9.3.0
         Environment: * CloudStack 4.9.3 / CentOS7
* KVM / 4.9.3 / CentOS7
* Issue observed on isolated and shared networks
            Reporter: Dag Sonstebo


Steps to reproduce:
* Create isolated or shared network with running VM
* Confirm that everything works OK - DNS resolution and DHCP.
* Restart network with cleanup.
* On new VR check DNS and DHCP settings.
* Result:
** /etc/dnsmasq.d/cloud.conf: file is missing, hence no base DHCP config
** /etc/hosts: file present but missing all user VM entries, hence no DNS resolution
** /etc/dhcphosts.txt: file is missing, hence no DHCP 
** /etc/cloudstack/dhcpentry.json: file is present and contains expected JSON VM entries 

As a result the new VR:
* Will not hand out DHCP entries
* Will not do name resolution

Workaround:
* Creating new VM or stopping and starting a VM restores all settings.
