Some OSes (e.g. Windows Server 2012 R2) fail to boot after virt-resize due to changed disk guid. To fix it, we add new APIs: part_get_disk_guid part_set_disk_guid part_set_disk_guid_random We also preserve disk GUID in virt-resize.

New API: part_set_disk_guid_random. resize: preserve GPT disk GUID. daemon/parted.c | 75 ++++++++++++++++++++++++++++++...

If we want to permit more than 255 drives to be added, then we will have to add the disks to the same virtio-scsi target using different unit (LUN) numbers. Unfortunately SCSI LUN enumeration in the Linux is not deterministic (eg. two disks with target=0, lun=[0,1] can be enumerated as /dev/sda or /dev/sdb randomly). Dealing with that will require some very complex device name translation on the

Split up the huge generator/actions.ml into several smaller files. Rich.
