Haitao Shan -----Original Message----- From: Christoph Egger [mailto:Christoph.Egger@xxxxxxx] Sent: 2008å9æ9æ 17:07 To: xen-devel@xxxxxxxxxxxxxxxxxxx Cc: Shan, Haitao; Keir Fraser; Gavin Maltby Subject: Re: [Xen-devel] [PATCH 0/4] CPU online/offline support in Xen SUN also has code for physical cpu hotplugging. So this is duplicate work now. Please get into contact with each other and merge your patches.
