Question #14

  2. B
    pae =1
  3. C
    builder=’hvm’
  4. D
    serial=’pty’

Correct Answer:
C
My suggestion is to use builder=hvm because it works fine for once I have failed to booting the server but when I made it builder=hvm it booted fine. Another thing is if you use linux os as a mother os then you can leftover this builder=hvm but if you use windows2003 then you have to use builder=hvm.
