This fixes a crash in hot-unplug of virtio-pci devices behind a PCIe switch. The crash happens because the ioeventfd is still set whent the child is destroyed (destruction happens in postorder). Then the proxy tries to unset to ioeventfd, but the virtqueue structure that holds the EventNotifier has been trashed in the meanwhile. kvm_set_ioeventfd_pio does not expect failure and aborts. The fix is simply to move parts of uninitialization to a new device_unplugged callback, which is called before the child is destroyed.

Right now we have these pairs: - virtio_bus_plug_device/virtio_bus_destroy_device. The first takes a VirtIODevice, the second takes a VirtioBusState - device_plugged/device_unplug callbacks in the VirtioBusClass (here it's just the naming that is inconsistent) - virtio_bus_destroy_device is not called by anyone (and since it calls qdev_free, it would be called by the proxies---but then the callback is useless since the proxies can do whatever they want before calling virtio_bus_destroy_device) And there is a k->init but no k->exit, hence virtio_device_exit is overwritten by subclasses (except virtio-9p). This cleans it up by: - renaming the device_unplug callback to device_unplugged - renaming virtio_bus_plug_device to virtio_bus_device_plugged, matching the callback name - renaming virtio_bus_destroy_device to virtio_bus_device_unplugged, removing the qdev_free, making it take a VirtIODevice and calling it from virtio_device_exit - adding a k->exit callback virtio_device_exit is still overwritten, the next patches will fix that.

Similar to the PCI bug that prompted these patches, virtio-ccw will segfault after the reworking of hotplug/hot-unplug. Prepare for this by moving virtio_ccw_stop_ioeventfd to before the freeing of the proxy device. A better place for this could be the device_unplugged callback for the virtio-ccw bus. However, we do not yet have a callback that works: this patch avoids the problem while leaving the tree bisectable.

Performing multiple drive-mirror blockjobs on the same qemu instance results in the image file used for the block device being replaced by the newly mirrored file, which is not what we want.

For "none" sync mode in "absolute-paths" mode, the current image should be used as the backing file for the newly created image. The current behavior is: a) If the image to be mirrored has a backing file, use that (which is wrong, since the operations recorded by "none" are applied to the image itself, not to its backing file). b) If the image to be mirrored lacks a backing file, the target doesn't have one either (which is not really wrong, but not really right, either; "none" records a set of operations executed on the image file, therefore having no backing file to apply these operations on seems rather pointless). For a, this is clearly a bugfix. For b, it is still a bugfix, although it might break existing API - but since that case crashed qemu just three weeks ago (before 14526864), we can safely assume there is no such API relying on that case yet.

The default granularity for the FIT timer on 440 is on every 0x1000th transition of TB from 0 to 1. Translated that means 48828 times a second. Since interrupts are quite expensive for 440 and we don't really care about the accuracy of the FIT to that significance, let's force FIT and WDT to at best millisecond granularity. This basically restores behavior as it was in QEMU 1.6, where timers could only deal with millisecond granularities at all. This patch greatly improves performance with the 440 target and restores roughly the same performance level that QEMU 1.6 had for me.

Today we fire FIT and WDT timer events every time the respective bit position in TB flips from 0 -> 1. However, there is no need to do this if the end result would be that we're changing a TSR bit that is set to 1 to 1 again. No guest visible change would have occured. So whenever we see that the TSR bit to our timer is already set, don't even bother to update the timer that would potentially fire it off. However, we do need to make sure that we update our timer that notifies us of the TB flip when the respective TSR bit gets unset. In that case we do care about the flip and need to notify the guest again. So add a callback into our timer handlers when TSR bits get unset. This improves performance for me when the guest is busy processing things.

The service will automatically be removed when the COM+ application is deregistered. This patch replaces ICOMAdminCatalog interface with ICOMAdminCatalog2 interface that contains CreateServiceForApplication() method in addition.
