Hi, I recently upgraded from Xen 4.1.3 to Xen 4.4 and now pass through is not working for me. If I do xl dmesg, it says IOMMU is disabled because of the x58 erranta. This is frustrating because this board is working in 4.1.3 and it should not be detected as a problem case. So I set iommu=force in grub and reboot and then Xen doesn't boot. Is there anything else I can try? Or do I have to stay on 4.1.3? Thanks. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
