Hi All: Fisrt please forgive my poor english I want to get some suggestion I have tow IB card in my host : CentOS5.5 Xen3.0.3 When I use Redhat Kernel . I can get 800MB/s each card. That means I can have 1.6G bandwidth Then I change to the Xen Kernel. And I can only get 800MB or more lease when I try to write a disk Read disk can have 1.6G It seems like that xen can''t use two card at the same time Thanks for your reply Gong ICT in AC Beijing China _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
