Xen 3.2.1, LVM et Windows XP avec deux disques en NTFS
Par david techer, vendredi 5 février 2010 à 01:39 :: Xen
Intérêt: L'accès en LVM offre de meilleures performances par rapport aux accès disques depuis un simple fichier image.
Idée: avoir mon C: et mon D: comme d'habitude sous Windaube :)...
Motivation: un peu la flemme ce soir de rédiger ce billet, donc copier coller de mon history
