First off, I suggest you look into Windows Server 2008 and Hyper-V
(with SCVMM) instead of Windows Server 2003 and Windows Virtual
Server 2005 for your virtualization needs.
* Is this secure and stable ?
Depends on how you harden the box (both the host and guest(s)). For a
more secure stable MS-cluster solution, go for Windows Server 2008
Clustering + Hyper-V + SCVMM (System Center Virtual Machine Manager).
I would recommend configuring your host/parent partition to run
Windows Server Core 2008 for a much smaller OS footprint (lower attack
surface), install the Hyper-V role (Hyper-V is a much improved,
"thinner" hypervisor), and setup SCVMM on another box to serve as a
single point of management for your entire virtualization

* Will we have easy implementation and managment ?
It depends on your requirements. Factors like number of cluster nodes,
dispersed nodes (geo-cluster) requirements, storage requirements,
administration/management considerations etc could increase the level
of complexity of your implementation. Here's a whitepaper scenario
from Technet that details how you can use Windows Virtual Server 2003
to create and configure a two-node Windows Server 2003 cluster:
Again, as mentioned above, Windows Server 2008 offers a much robust
platform and easier deployment methods as compared to Windows Server
2003. Use SCVMM to manage your virtualization infrastructure from a
single management point:

* Which software use MS to make clusters ?
Microsoft uses MSCS or Microsoft Cluster Service for Windows Server
2003; for Windows Server 2008, it is uses Failover Clustering (role).
