[Xen-users] My Xen 3.0.3m doesn''t reconize my new RAM
Hello I''ve just added 2Gb of RAM on my Xen Host but this one think always it have 1G ... I can''t start VM. It tell me that dom0_min_mem is 196 and shrinking ... What is the procedure to force Xen to reconize this memory ? It''s very strange because a #xm list returns 3gb for dom0 regards _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
