I tried to use 'xl pci-attach' and 'xl pci-detach' with the module acpiphp in the guest, this work fine. But xen say: (XEN) domctl.c:992:d0 memory_map:remove: gfn=20000 mfn=da000 nr_mfns=2000 (XEN) p2m.c:2723:d0 clear_mmio_p2m_entry: gfn_to_mfn failed! gfn=0002000c The error append only when the pci device is still attach to the guest when I type 'halt' in the guest. -- Anthony PERARD _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
