Get the image from vt-nfs:/images/sriov 2. Boot from the 2.6.18.8 kernel, which includes 0.9.5 VF driver 3. To boot from latest VF driver, you can boot from the entry named "2.6.30" -- Configure bugmail: http://bugzilla.xensource.com/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. _______________________________________________ Xen-bugs mailing list Xen-bugs@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-bugs
