For cluster we need a Quorum disk. Below are the steps to make a Quorum virtual disk. In the menu of Virtual Server, click on "Create" under "Virtual Disks" and select "Fixed Size Virtual Hard Disk".
Create Virtual Disk
After clicking there, you should get below screen. Fill in the details as shown. E:\Virtual Server\Q-Drive.vhd is the path which I have entered. Lets give size as 250 MB.
Q Drive 
And click on Create. you should see vhd file under path which we provided in above screen.

Create heartbeat Network

Click on "Create" under "Virtual Networks" and provide below details as shown below.
Give Name as HeartBeat and "Network adapter on physical computer" to be select as "None (Guests Only)"
HeartBeat
Click on "OK"

Add SCSI Adapters

Now to attach this to MyNode1 and MyNode2, we need to Turn Off those machine.  Go to "Master Status" link and select link to "Turn Off"
Once done, we need to choose "Edit Configuration" as shown below:
MyNode1_Edit Configuration
At “MyNode1” Configuration page, click on SCSI adapters as shown below
SCSI
Then you will get a screen like below
Add SCSI Adapter
Click on the button and fill information as below. make Sure that you check "Share SCSI bus for clustering" and ID as 7.
MyNode1_SCSI_ID7
And Click "OK"
You should see below on final screen.
Final Setting SCSI MyNode1
Above Steps to be done as MyNode2 also. Difference is SCSI adapter ID. For MyNode2 it should be ID as 6.
MyNode2_SCSI_ID6
here also, Click OK once added.

Add Network Adapters

Go back to "Edit configuration" Page for MyNode1 and this time we will choose "Network Adapters"
Network Adapters
You will get below screen
MyNode1 Network Adapter1 
Click on "Add Network Adapter >>" and Provide "HeartBeat" network.
MyNode1 Network Adapter2
Hit "OK"
Follow the same steps with MyNode2 configurations
MyNode2 Network Adapter2
Hit "OK"

Add Quorum Disk to Both Nodes

Below steps are self explanatory.
Go to Edit Configuration for MyNode1 and click on "Hard disks"
MyNode1 HardDisks
One you click, you will get below screen. Fill in the location of Q Drive which we created earlier. (E:\Virtual Server\Q-Drive.vhd)
Quorum MyNode1
Now, Start MyNode1 and log on to the node. we need to format the drive which we attached in above step and call it drive Q.
MyNode1 Manage
Clicking on Disk Management would result in below screen.
MyNode1 Initialize and Convert disk
Select all default setting and finish the Wizard (don't make any modifications)
Unallocated
Then Right click on the Disk and assign drive letter Q: to it (as below)
Assign Drive letter
On Finishing this you would be able to see Q drive in My Computer.
This finishes shared disk on MyNode1. Shutdown this Node because in order to attach and configure the shared disks to the cluster nodes, you must ensure that the other node is turned off (In our case MyNode1 should be off).
a. Logon to MyNode2 and Right-click My Computer, click Manage, and then expand Storage.
b. Double-click Disk Management.
c. The shared drives are listed, but have not been assigned a drive letter. Right-click the drive and select Change Drive Letter and Paths.
d. Click Add.
e. Use the drop-down box to change the drive letter to Q, and press OK.
MyNode2 Q Drive
Now you should be able to See Q drive in My Computer on MyNode2. This finishes setting up shared disk for Both the Nodes.
Ahh.. this page has lots of screen and it would be slow to load. I am continuing in Part 3.
