I can enable iommu with iommu=no-intremap but (XEN) Intel VT-d iommu 0 supported page sizes: 4kB. (XEN) Intel VT-d Snoop Control not enabled. (XEN) Intel VT-d Dom0 DMA Passthrough not enabled. (XEN) Intel VT-d Queued Invalidation enabled. (XEN) Intel VT-d Interrupt Remapping not enabled. (XEN) Intel VT-d Shared EPT tables not enabled. Is thre better way to enable iommu on server. _______________________________________________ Xen-users mailing list Xen-users@lists.xen.org http://lists.xen.org/xen-users
