win2008 guest boot correctly without "-mem-path /mnt".

Andrea,
I wouldn't fix this bug, and we can probably close this bug using a tech-note that describes the limitations.

Comment 3 Ronen Hod 2013-03-28 18:23:30 UTC

Please take a look at Comment 1 and write a short tech-note.
I will close this bug.
