Ritu,

That tutorial is a bit old.

Let me try to answer them, i do have an alternative solution, perhaps we 
can get on the phone and do a webex session or something similar - this 
week is bad for me, i'm traveling, but next week, Thursday and beyond - 
my schedule is flexible. I assume you are on PST timezone somewhere in 
bay area.

Please see response inline to your inquiries.

The path is incorrect, this use to apply to CloudStack 4.0 or 4.1, but 
anything post 4.2 has cloudstack in its path.
Here is the snippet of my install script:

/usr/share/cloudstack-common/scripts/storage/secondary/cloud-install-sys-tmplt 
-m /mnt/nfs/secondary -u 
http://my-webserver/systemvm64template-latest-master-vmware.ova -h vmware -F

Note that /mnt/nfs/secondary - is nfs mount - either local or remote
That mount must be accessible by hypervisors. Cloudstack needs to access 
hypervisors and vcenter on port 443.

Depends on your setup. Storage network is used when you have a separate 
segregated NFS or alike storage network. In that case, that storage 
network must be trunked  to you hypervisors.
If you are deploying for POC and you dont have a specific storage 
network, dont add storage network traffic label.
Public network - also depends on your setup, if you are doing Advanced 
Zone with VPC (amazon like cloud), you will need a larger IP pool as you 
want to assign public IPs to your guest VMs. However, if you are 
deploying Advanced Shared  Zone without VPC, where you are using your 
physical network and routers/firewalls, then all you need is 2 public 
ips per zone - which arent really public in the internet sense.

Cloudstack deploys System VMs in following fashion.
Per zone, you have:

Advanced Shared Zone (non VPC)
- Storage VM - doing storage things
    uses 1 public ip and 1 management ip (private communication link)

- Console Proxy VM - proxies VNC console session from hypervisor to end user
    uses 1 public ip and 1 management ip (private communication link)

- RouterVM - 1 per VLAN
    uses 1 management ip (private communication link)

Advanced Shared Zone (VPC - dont use this type of env so i'm not certain 
- but from what i'm told)
- Storage VM - doing storage things
    uses 1 public ip and 1 management ip (private communication link)

- Console Proxy VM - proxies VNC console session from hypervisor to end user
    uses 1 public ip and 1 management ip (private communication link)

- RouterVM - 1 per VLAN per Account
    uses 1 management ip (private communication link)

It depends yet again :) If you have VMFS datastores, then yes you have 
to specify existing VMFS store already defined in vCenter.
If you are doing NFS, then cloudstack will create it on your behalf.
