Hi Michael, A git bisect turned out that commit 9e047b982452c633882b486682966c1d97097015 breaks pci-passthrough on Xen. commit 9e047b982452c633882b486682966c1d97097015 Author: Michael S. Tsirkin <m...@redhat.com> Date: Mon Oct 14 18:01:20 2013 +0300 piix4: add acpi pci hotplug support Add support for acpi pci hotplug using the new infrastructure. PIIX4 legacy interface is maintained as is for machine types 1.7 and older. Signed-off-by: Michael S. Tsirkin <m...@redhat.com> The error is not very verbose : libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP server: Device initialization failed. libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP server: Device initialization failed. libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP server: Device initialization failed. libxl: error: libxl_qmp.c:287:qmp_handle_error_response: received an error message from QMP server: Device initialization failed. So it seems there is an issue with preserving the legacy interface. -- Sander
