When converting hardware virtualized machine to full PV, the guest falls to boot. What line in vm.cfq is likely leftover from the HVM configuration? 

Answer options:

A. vnclisten = `0.0.0.0`
B. pae =1
C. builder=’hvm’
D. serial=’pty’

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.
