Syntax error in dnsmasq config file while deploying vm in a new subnet
Steps to Reproduce:
=================
1.Bring up CS in basic zone with xen61 server.
2.Add guest ip range in a different cidr compared to what was given during zone
deployment.
3.Try to deploy vm using the ip address from new cidr
Expected Result:
==============
When CS tries to deploy guest vm with the ip from new CIDR an ip alias should
be created on domR and dnsmosq conf should be updated with new cidr info and
dnsmasq should be reloaded.
Actual Result:
============
On domR ip alias was created but observed syntax error in dnsmasq.conf file due
to which dnsmosq reload failed and vm deployment also failed.
Observations:
===========
