Recent discussions on xen-devel have highlighted that to properly support displacing emulated NVMe disks with PV equivalents will need updates to PV frontends. Therefore it is important that, if an emulated NVMe disk is exposed to a guest with an existing PV storage frontend, that frontend does not inadvertently cause unplug of that emulated disk when unplugging IDE or SCSI disks. This patch defines a new bit in the mask used to instruct QEMU to unplug emulated devices which will instruct QEMU to unplug NVMe disks and limits the semantics of the existing 'all' disk-unplug bit to only IDE and/or SCSI disks.

xen-bugtool =========== The xen-bugtool command line application will collate the Xen dmesg output, details of the hardware configuration of your machine, information about the build of Xen that you are using, plus, if you allow it, various logs. The information collated can either be posted to a Xen Bugzilla bug (this bug must already exist in the system, and you must be a registered user there), or it can be saved as a .tar.bz2 for sending or archiving. The collated logs may contain private information, and if you are at all worried about that, you should not use this tool, or you should explicitly exclude those logs from the archive. xen-bugtool is wholly interactive, so simply run it, and answer the questions.
