From ef18310d5495c4ce0e1289ed7fc9833d73fe5ee1 Mon Sep 17 00:00:00 2001 From: Eduardo Habkost Date: Sat, 25 Nov 2017 13:16:10 -0200 Subject: [PATCH] q35: Allow only supported dynamic sysbus devices The only user-creatable sysbus devices in qemu-system-x86_64 are amd-iommu, intel-iommu, and xen-backend. xen-backend is handled by xen_set_dynamic_sysbus(), so we only need to add amd-iommu and intel-iommu.
