-------------------------------------
Summary: [Multiple_IP_Ranges] user data service on VR does not
work in case of multiple subnets
Key: CLOUDSTACK-2644
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-2644
Project: CloudStack
Issue Type: Bug
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.2.0
Environment: Latest build on master:
CloudStack-non-OSS-MASTER-394-rhel6.3.tar.gz
Reporter: Sanjeev N
Priority: Critical
Fix For: 4.2.0
user data service on VR does not work in case of multiple subnets
Steps to reproduce:
================
1.Bring up CS in basic zone with xenserver6.1
2.Exhaust all the guest IP addresses in primary ip range
3.Add new guest IP range in new subnet
4.Deploy guest vm with user data using the IP address in new ip range.

5.Fetch the user data
Expected behavior:
================
from the guest vm executing the following command should fetch the guest vm
userdata provided while deploying guest vm:
curl http://10.147.43.195/latest/user-data
Actual Result:
=============
fetching userdata failed :
[root@e3e13452-7e1e-4939-95c0-c64c333d6937 ~]# curl
http://10.147.43.195/latest/user-data
curl: (7) couldn't connect to host
Observations:
============
On VR userdata service is running as a web server and listening on primary IP
address and port 80.
Following is the content of the /etc/apache2/port.conf :
# If you just change the port or add more ports here, you will likely also
# have to change the VirtualHost statement in
# /etc/apache2/sites-enabled/000-default
# This is also true if you have upgraded from before 2.2.9-3 (i.e. from
# Debian etch). See /usr/share/doc/apache2.2-common/NEWS.Debian.gz and
# README.Debian.gz
NameVirtualHost 10.147.43.6:80
Listen 10.147.43.6:80
<IfModule mod_ssl.c>
# If you add NameVirtualHost *:443 here, you will also have to change
# the VirtualHost statement in /etc/apache2/sites-available/default-ssl
# to <VirtualHost *:443>
# Server Name Indication for SSL named virtual hosts is currently not
# supported by MSIE on Windows XP.
Listen 10.147.43.6:443
</IfModule>
<IfModule mod_gnutls.c>
Listen 10.147.43.6:443
</IfModule>
But in case of multiple IP subnets, for every subnet one ip alis gets created
on router vm with IP address from each subnet. So the guest vm deployed in new
subnet can't fetch the userdata since there is no userdata service listening on
the ip alias address belongs to that subnet.
Either userdata service should listen on 0.0.0.0 ip address or for every ip
alis address one entry should be created in /etc/apache2/ports.conf file to
provide user data service to the guest vms in each subnet.
