I managed to get my R9 270 passed also HD6450 at same time. I can boot fine windows 8.1 and shut down. I can get it rebooted without xen rebooting whole system. I saw there is kernel path acs overide http://www.spinics.net/lists/kvm/msg92163.html I wonder if that will have impact on vga passthrough i wonder if changing on_reboot = 'restart' destroy will fix reboot issue ati drivers are going crazy. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
