Change in vdsm[master]: image: copying a template is always allowed
by Federico Simoncelli
Federico Simoncelli has uploaded a new change for review.
Change subject: image: copying a template is always allowed
......................................................................
image: copying a template is always allowed
To copy a template from a domain to another is a safe action even if
it has images that are based on it. This patch relaxes the check during
moveImage if the operation is a copy.

[WIP] Added getStorageDevices verb.
This verb is used to get list of storage devices in the node. Return
value is a dictionary, its keys are device names and values are
properties of those devices as dictionary.
{DEVNAME: {'container': CONTAINER_DEVNAME,
'contentType': CONTENT_TYPE_STRING,
'endSize': SIZE_MB,
'flagList': STRING_LIST,
'fsSize': SIZE_MB,
'fsSizeFree': SIZE_MB,
'fsType': STRING,
'fsUuid': UUID,
'members': DEVNAME_LIST,
'model': STRING,
'mountPoint': STRING,
'name': DEVNAME,
'origin': LV_DEVNAME,
'parent': PARENT_DEVNAME,
'partitions': DEVNAME_LIST,
'size': SIZE_MB,
'sizeFree': SIZE_MB,
'startSize': SIZE_MB,
'status': STATUS_STRING,
'tableType': DISK_TABLE_TYPE,
'type': TYPE_STRING,
'uuid': UUID,
'vendor': STRING},...}
here, property dictionary contains
container: If DEVNAME is used by another device eg. LVM PV, MD etc, name
of that device is set
contentType: This is determined by various other properties. Possible
value is one of 'SWAP', 'OS', 'DATA' and 'NA'
endSize: If DEVNAME is a partition, its end boundry is set. The value
is in MB
flagList: If DEVNAME is a partition, its flags(eg. boot,bios_grub etc)
are set as a list of strings
fsSize: If DEVNAME has a file system, its size is set. The value is
in MB
fsSizeFree: If DEVNAME is mounted, its free size is set. The value is in
MB
fsType: If DEVNAME is formatted, its file system type is set
fsUuid': If DEVNAME has file system, its UUID is set
members: If DEVNAME is a MD, LVM VG etc, its member device names are
set as list of strings
model: Model of DEVNAME is set as string
mountPoint: If DEVNAME is mounted, its mount point is set
name: DEVNAME is set here for completion
origin: If DEVNAME is a snapshot of LV, that LV name is set
parent: If DEVNAME is a partition, its disk name is set
partitions: If DEVNAME is a disk, its partition names are set as list of
strings
size: Size of DEVNAME is set. The value is in MB
sizeFree: If DEVNAME is VG, its size of free extents is set. If its a
partitioned disk, its unallocated size is set. The value is
in MB
startSize: If DEVNAME is a partition, its start boundry is set. The
value is in MB
status: This is determined by various other properites of the DEVNAME.
Possible value is one of 'UNINITIALIZED', 'NA', 'UNUSABLE',
'FORMAT_UNSUPPORTED', 'MOUNTED', 'FORMATTED' and 'PARTED'
tableType': If DEVNAME is a disk, its table(label) type is set as a string
type: This is determined value. Possible value is one of 'MD',
'LVM_VG', 'LVM_LV_SNAPSHOT', 'LVM_LV' and 'BLOCK'
uuid: UUID of DEVNAME
vendor: Vendor of DEVNAME is set as string
