> 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:
> ===========
