But I did the shutdown from within the guest (poweroff).For me it makes no difference timewise whether I issue a xl shutdown guest from dom0 or whether I issue shutdown -h now from a connection (i.e. ssh or screen or console) to the guest. The main difference being that for the latter the delay is visible whereas for the former, the delay is not so obvious because 'xl shutdown guest' from dom0 due to its asynchronous nature returns immediately even when the guest is still alive. One difference that I have noticed however is that for the shutdown from _within_ the guest (i.e. shutdown -h now) the state of the guest remains 's' in 'xl list' from the time the "system halted" message appears on screen until the prompt returns in dom0 whereas for a shutdown from dom0 with 'xl shutdown guest' the state changes from 's' to 'ps' for a number of seconds before it is finally gone.Does it look anything like this? marc.info/?i=<CAFLBxZbOdU=uSwNBVRTB7_7yhPyRShda0asSOvv9J+xfoGxRnA@xxxxxxxxxxxxxx> (the log in question is /var/log/xen/xl-$DOMAINNAME.log) -George _______________________________________________________________________ Waiting for domain voip (domid 3) to die [pid 2274] Domain 3 has shut down, reason code 0 0x0 Action for shutdown reason code 0 is destroy Domain 3 needs to be cleaned up: destroying the domainlibxl: error: libxl_pci.c:1250:do_pci_remove: xc_domain_irq_permission irq=17 libxl: error: libxl_device.c:1134:libxl__wait_for_backend_deprecated: Backend /local/domain/0/backend/pci/3/0 not ready (state 7) libxl: error: libxl_device.c:1138:libxl__wait_for_backend_deprecated: FE /local/domain/3/device/pci/0 state 6 libxl: error: libxl_pci.c:1250:do_pci_remove: xc_domain_irq_permission irq=16 libxl: error: libxl_device.c:1134:libxl__wait_for_backend_deprecated: Backend /local/domain/0/backend/pci/3/0 not ready (state 7) libxl: error: libxl_device.c:1138:libxl__wait_for_backend_deprecated: FE /local/domain/3/device/pci/0 state 6 libxl: error: libxl_pci.c:1250:do_pci_remove: xc_domain_irq_permission irq=23 libxl: error: libxl_device.c:1134:libxl__wait_for_backend_deprecated: Backend /local/domain/0/backend/pci/3/0 not ready (state 7) libxl: error: libxl_device.c:1138:libxl__wait_for_backend_deprecated: FE /local/domain/3/device/pci/0 state 6 libxl: error: libxl_device.c:894:device_backend_callback: unable to remove device with path /local/domain/0/backend/pci/3/0 libxl: error: libxl.c:1452:devices_destroy_cb: libxl__devices_destroy failed for 3 Done.
