COMMANDS
clone Clone a given VM or template to another VM name. If -c is specified multiple
copies are made. Each VM name will be incremented in the usual Perlish way. e.g.:
DB1, DB2, DB3 etc.
If -a is unspcified the datastore of the source VM is copied as the new clones
datastore. If -a is specified the data store will be set during cloning. If -a
contains a comma denoted list the datastores will be alternated during cloning.
e.g. -a 1,2 copies to datastore 1 then 2 then starts again at 1. Patterns of
repeating datastores can be specified - e.g. '-a 1,2,3,2,1'.
deploy Synonym of 'clone'.
df Display disk usage information about datastores. If a list of matches is
provided, the data store list is filtered for those items.
list Display a list of the given items matching a pattern.
Possible lists include (selection can be plural or singular):
vms (default if unspecified)
datastores
hosts
pools
If '-d' is specified without any containing '$' marks the string is evaluated as a
CSV with each line extracting the requisite information that would be shown with
the 'show' command. See the EXAMPLES section for further information.
If '-d' is specified and contains a '$' it is evaluated as a perl expression with
$_ being set to the currently active item.
If '-t' is spcified the titles header for the table is set.
migrate Migrate a given list of VMs to another host.
move Move a given list of VMs to another datastore.
setpool Set the share level on the given resource pools.
show Show information about a given object. If no specific object type is specified
'vm' is assumed. If no specific matching pattern is specified all objects of that
type are listed.
snapshot
Take a snapshot of the matching VM's. If '-t' is specified, it is used as the
title of the snapshot. Otherwise the current time is used.
state Set the state of a list of VMs.
This can be any of the following choices:
on - Power up the specified VMs
off - Power down the specified VMs. This is a hard power state so data loss could occur.
suspend - Power the machine into standby mode. This is a hard power state which does not rely on VMware tools.
restart - Hard power cycle the VMs. Like 'off' this is a forced power state so data loss could occur.
shutdown - Try shutting down the machine via VMware tools.
standby - Try to put the machine into the soft standby state.
reboot - Try shutting down the machine via VMware tools.
version Display various version informaiton about the connected vServer and local API.
This command is the default if no actual command is specified (i.e. just running
'vwm' with nothing else specified).
OPTIONS
[@profile]
Used during: All operations
Default: First specified profile in config
Type: Profile name or URL
Specifies which profile to use when addressing the vServer. This can be an entry
within the config file or the URL (with optional login details) e.g.
vwm version @cluster1
vwm version @cluster2
vwm version @https://cluster1.acme.edu
vwm version @https://[email protected]
vwm version @https://username:[email protected]
Examples 1 and two assume 'custer1' and 'customer2' have been defined in the
examples file (see EXAMPLES). The further examples specify the connection
information on the command line. Specifying the password from the command line is
exceptionally silly and should be avoided.
If username and/or password is omitted (such as in examples 3 and 4 above) they
will be prompted for when vwm is run.
-c
Used during: migrate
Default: 1
Type: Number
Specifies how many VMs should be created during a clone operation. The name of
the target VM is incremented in the usual Perlish way. e.g.
DBS1, DBS2, DBS3... DBS10 DB00, DB01, DB02... DB99 DBAA, DBAB, DBAC... DBZZ
--display [col1,col2...]
-d [col1,col2...]
Used during: list
Default: Name
Type:
Command seperated list of columns to display in tabular output when using the
'list' command. See also: -s to specify the seperation character to use
between the columns.
Specify a data store for operations that require it.
--datastore [datastore]
--ds [datastore]
-a [datastore]
Used during: migrate
Default: Same as source VM
Type: Datastore name
Specify a data store for operations that require it.
--force
-f
Used during: All operations
Default: off
Type: Switch
Force continue if an error occurs. Normaly if an error occurs vwm will stop
processing any operations specified on the command line. If this flag is enabled
vwm will continue operation as if no error occured.
--human
-h
Used during: df
Default: off
Type: Switch
Display the numbers of the 'df' command in a human readable format.
--dryrun
-n
Used during: All operations
Default: off
Type: Switch
Dry run mode. When enabled vwm will continue as normal but no actual call to the
VMware VServer is made.
--folder
-l
Used during: clone
Default: Source VM / templates folder
Type: String
Specifies the folder that the cloned machine should be moved into. If unspecified
the source VM's folder is used instead.
--pool [pool]
-o [pool]
Used during: clone, migrate, move
Default: Same as the source VM
Type: Pool name
Specifies the alternate pool name to use when migrating or cloning machines. If
unspecified the source VM's pool is used instead.
--priority [priority]
-p [priority]
Used during: migrate
Default: low
Type: Choice of: low, normal, high
Specifies the priority when migrating VMs.
--seperator [character]
-s [character]
Used during: list
Default: \t (tab)
Type: String
Specifies the string to display between columns when outputing a list.
--title [title]
-t [title]
Used during: list, snapshot
Default: The Unix EPOC (for VMs)
Type: String
The title of the snapshot to create or the title row of the list table.
-v
--verbose
Used during: All operations
Default: 0
Type: Accumulating switch
Be more verbose when outputting information to STDERR. Specify multiple times to
increase verbosity.
-w [seconds]
-wait [seconds]
Used during: clone, host, migrate, setpool, state
Default: 0
Type: Number of seconds
Force a wait for the specified number of seconds between operations.
DESCRIPTION
A command line tool for the manipulation of VMware Virtual Machines (VM).
EXAMPLES
vwm clone VM01 VM02
Clone VM01 to VM02. Since neither the datasource (-d) or pool (-o) is specified these
details are copied from VM01.
vwm clone DB00 DB01 -c 30
Clone DB01 to DB02 creating 30 copies. This will actually make the machines DB01 to
DB30. Since neither the datasource (-d) or pool (-o) is specified these details are
copied from VM01.
vwm clone DB00 DB01 -c 30 -d SAN1,SAN2 -o Active
Same as the above example but spread the datastores across SAN1 and SAN2 and move the
machine to the 'Active' pool.
vwm deploy Template-DBServer DB05 -l Databases
Deploys the template Template-DBServer into DB05, moving the destination into the
Databases folder.
vwm clone Template-DBServer DB05 -l Databases
This is exactly the same as above. A clone and deploy operations will automatically
figure out if the source is a template and act accordingly.
vwm df *2
Display a datastore usage sheet (similar to the Unix 'df' command) for all datastores
ending in '2'.
vwm host maintenance Moe Homer
Put the hosts 'Moe' and 'Homer' into maintenance mode (use 'restore' to recover from
this).
vwm list vms
List all VMs.
vwm list vms -d name,host,ip
List all VMs - showing their name, currently allocated host and IP address.
vwm migrate DBS* Carl
Migrate all virtual machines matching 'DBS*' to the 'Carl' host.
vwm migrate DBS* Lenny -w 60 -o Active -p high
Migrate all virtual machines matching 'DBS*' with high priority to the 'Active' pool
on the 'Lenny' host waiting 60 seconds between machine.
vwm move DB00 DB01 SAN2 @cluster2
Move VMs DB00 and DB01 to the SAN2 datastore within profile 'cluster2'.
vwm show host Lisa
Show information on host 'Lisa'.
vwm snapshot DB04 DB05 -t 'Todays backup'
Take a snapshot of VMs 'DB04' and 'DB05' using the title 'Todays backup'
vwm state on DB00 DB01 -w 30
Turn DB00 and DB01 on waiting 30 seconds between machines.
vwm state on DB00 DB01 -w 30 -f
Turn DB* VMs on. -f ensures that even if any of the machines fail to turn on for any
reason the remaining machines will still be sent the 'on' command.
Use vwm online using onworks.net services
