Issue:

While creating/adding new machines to a machine catalog, if you mention 10 VDIs to create, xendesktop would create only 1 or 2, or some random number below 10, but not exactly 10.

Reason:

This happens because you have orphan AD accounts in your machine catalog.

Solution:

You have to remove those orphan AD accounts from your machine catalog. If your machine catalog has no other issues, Xendesktop would create the number of machines you specify in “add machines” option in a machine catalog.

Follow the steps given here to remove orphan AD accounts:
