Interested in script critique

This script:

1.     Connects to VC entered by user.

2.     Reads virtual machine names from a csv.

3.     Sets vCPU, memory.

4.     Sets video memory (from function - Thanks Alan).

5.     Sets CPU/MMU to software.

6.     Powers on VM.

7.     Disconnects from VC.

Interested in any feedback on if this could be arranged differently or made more efficient.

Also, interested in how to get rid of this type feedback in the console during this line.
