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.
