some more googling seems to indicate that this only works for intel vt because amd doesn't have a iommu for virtualization until very recent (2009) processors and it also sounds like xen only has the beginnings of support for that. so if you have some intel vt hardware to test with, that might be the next step. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
