Date Tue, 17 Sep 2019 19:46:00 GMT

    [ https://issues.apache.org/jira/browse/CLOUDSTACK-10167?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16931771#comment-16931771

efansoftware commented on CLOUDSTACK-10167:
-------------------------------------------

[~aconn21], Is your script a totally new one or updates to existing one? If it is new one
what is your recommendation the best place to call it in CS-4.9.2.0 code base? Thanks!

>                 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: 4.9.2.0, 4.9.1.0, 4.9.0.1, 4.9.3.0
>         Environment: * CloudStack 4.9.3 / CentOS7
> * CloudStack 4.9.2 / CentOS7
> * CloudStack 4.9.1 / CentOS7
> * CloudStack 4.9.0.1 / CentOS7
> * KVM / 4.9.1 + 4.9.2 + 4.9.3 + 4.10.0 / CentOS7
> * XenServer 6.5 SP1
> * VMware vSphere 6.5
> * Issue observed on isolated and shared networks
> * 4.6 "new" system VM templates: http://packages.shapeblue.com/systemvmtemplate/4.6/new/
>            Reporter: Dag Sonstebo
>            Priority: Major
>
> Note: problem seems to be only in 4.9.x, seems fixed in 4.10.
> Environment:
> * CloudStack 4.9.3 / CentOS7
> * CloudStack 4.9.2 / CentOS7
> * CloudStack 4.9.1 / CentOS7
> * CloudStack 4.10.0 / CentOS7
> * Tested and reproduced with:
> ** KVM / 4.9.1+4.9.2+4.9.3 / CentOS7
> ** XenServer 6.5 SP1
> ** VMware vSphere 6.5
> * Issue observed on isolated and shared networks
> * 4.6 "new" system VM templates: http://packages.shapeblue.com/systemvmtemplate/4.6/new/
> 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.
