[Xen-users] are different Logical Volumes needed for Different DomU''s
Do I need different Volume Groups for different DomU''s or in same Volume Group which is 400GB in size I can create DomU LVM based images.Or I need to create separate DomU Logical Volumes as far as I understand xen-create-image creates the required LVMs so I don''t need to create them separately. -- Tapas +91 8971248477 _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Those LVs can be in the same or different VGs, your choice. I''ve never used xen-create-image though, so I can''t comment on that. -- Fajar _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Works quite nicely. That''s how we create all our PVMs on Debian/Ubuntu using Xen 3.1, 3.2, 3.3. -- Freddie Cash fjwcash@gmail.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
