Resizing a disk on the fly is useful, including for Xen guests. Xen has this capability, except in the case of qdisks (Xen QEMU disks). This patch series intends to provide this capability. With these patches, the xl command "qemu-monitor-command" can be used in conjunction with the "info block" and "block_resize" commands to help identify and then resize a Xen qdisk. It is anticipated that Xen's libxl will be extended to handle qdisk resizing without resorting to using the human monitor in this way, with libvirt support eventually building on top of that.
