Thanks for your quick reply.
One more thing that I want to confirm with you. I did as follows to deploy our virtual desktop.
1. Create master image with Win7 and install View Agent on it.
2. Shutdown master win7 image and take snapshot for linked clone.
3. Login to View administrator to deploy virtual desktop.
I think all virtual desktop with linked clone should share the snapshot which was taken in step2. As you mentioned,
all virtual desktops should share the disk of replicaXXXXXXXXXX, Is it right?
And Can I remove replicaXXXXX from vcenter inventory not deleting disk because the replicaXXXXXX has a really long name?
