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?
A.
vnclisten = '0.0.0.0'
B.
pae =1
C.
builder=’hvm’
D.
serial=’pty’
builder=’hvm’
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 amother os then you can leftover this builder=’hvm’ but if you use
windows2003 then you have to use builder=’hvm
A number of high priority virtual machines require significant file system access and you
are trying to decide what type of memory impact on dom0 they will have. Which two are

B.
You should not run a find command on dom0 as it will use up Dom0 memory and
potentiallycause double buffering with virtual machines.
C.
When increasing load with additional virtual machines, you should always add more
memory todom0.
D.
When increasing load with additional virtual machines, you generally wont add more
memory todom0.
