Hi Mr. Rajesh Battala,
Thanks a lot for your nice reply. We have installed NetScaler VPX (*Version 10.5-55.8*) on XenServer and using the 90 days free license. *We have tried the following steps for AutoScaling with NetScaler:* 1. We have installed cloudstack with with *Basic zone* and added netscaler by selecting the network offering as DefaultSharedNetscalerEIPandELBNetworkOffering. 2. We gave the management (pod) network as 192.168.1.0/24 (vlan1), guest network as 192.168.1.0/24 (vlan1) and public network as 192.168.2.0/24 (vlan2) 3. Registered an Ubuntu 12.04 server iso, installed an instance and prepared a template with snmp agent running on the VM and application running on 8080 port for the autoscaler. 4. Then we configured the autoscaler by clicking Network -> Configuration -> LoadBalancing -> configured a Autoscale rule (e.g., cpu >80% add VM and cpu<20% remove VM). But the problem we are having in this configuration is that we can not ping the public ip assigned to the autoscaler getting from public network (192.168.2.0/24). 5. We stopped the firewall in XenServer by using the command 'service iptables stop'. Not really sure the above steps are correct or not. Please let us know your valuable comments or suggestions. Waiting for your kind response. Thanks in Advance
