Tool to create and control virtual machines on ESXi servers
VM creation:
------------
-s <ip or domain name of ESX server>
-c Create new vm
-n <label> for the new virtual machine
-m <size> of RAM in megabytes. Can be omitted. Default is 512 MB
-d <size> of hard disk (M/G). Can be omitted. Default is 5 GB
--ds <datastore name> where VM will be created (optional)
--network <name> connect VM network adapter to specified virtual network(optional)
--mac <address> custom mac address for ethernet device. (must be started with 00:50:56)
--vncpass <password> set password to access vm console via vnc. Use this if you need non-interactive VM creation.
--novncpass omits setting vnc password so no authorization will be required
--iso <path> to ISO image in format of <datastore>/path/to/image.iso
--vmdk <path> to VMDK image in format of <datastore>/path/to/image.iso
--studio <appliance_id> Deploy appliance from SUSE Studio server, see studio options below
VM modification:
----------------
-e <vmid> <param to change> Edit existing VM. Available parameters for editing:
-n <label> Change label
--iso <path> Connect another iso image
--network <name> Switch to another virtual network
--vncpass <password> Change VNC passord
--vncpass -i interactively change password with checks
--novncpass remove password enabling connection without authentication
Cloning:
--------
--clone <vmid> Clone the specified VM. Can be extended with -n <label> and --ds <datastore> options
--toserver <esxi server> clone to *another* ESXi server. Do NOT use this option when cloning within one server
Exporting:
----------
--export <vmid> <local_directory> Export VM from ESXi to local desktop to use with VMWare desktop products(Workstation/Player)
Generic management:
-------------------
-l List all guests
--dslist List all datastores
--dsbrowse List files on specified datastore
--status <vmid> Get parametres of VM
--poweron <vmid> Power On VM
--bios Launch a VM's BIOS after start
--autoyast <network path> (http/ftp/nfs) to autoyast xml control file
--poweroff <vmid> Power Off VM
--reset <vmid> Reset VM
--vnc <vmid> Connect to VM via VNC
--showvncport <vmid> Print VNC port assigned to specified VM
--addvnc <vmid> Add VNC support to an existing VM ( guest need to be restarted to take effect)
--remove <vmid> Delete VM
Snapshot management:
--------------------
--snapshotlist <vmid> Get list of snapshots for current VM
--snapshot <vmid> --snapname <snapshot label> Make snapshot of current VM status
If --snapname is not specified the label will default to \"snapshot\$timestamp\"
--snapshotremove <vmid> --snapname <snapshot label> Remove a snapshot with specified name
--snapshotremove <vmid> --snapid <snapshot_id> Remove a snapshot with specified ID
--snapshotremove <vmid> --all Remove all snapshots for specidied VM
--revert <vmid> --snapname <snapshot label> Revert to snapshot by name
--revert <vmid> --snapid <snapshot id> Revert to snapshot by ID
SUSE Studio specific options:
-----------------------------
--studioserver <custom.server.com> Custom suse studio server ( if option is omitted susestudio.com is a default)
--apiuser <api_user> your SUSE Studio user (see http://susestudio.com/user/show_api_key )
--apikey <api_key> your SUSE Studio api key
--appliances Get appliance list from SUSE Studio
--buildimage <appliance_id> Build Preload ISO of specified appliance for deployment
--buildstatus <appliance_id> Get info on running builds of specified appliance
--format <image format> specify oemiso or vmx here
--help This help
Network Management:
-------------------
--networks <vmid> list networks used by VM
--vswitches list virtual switches
--nics list network adapters available on ESXi server
--vswitchadd <name> Create virtual switch with default corresponding network port group
--vswitchremove <name> Remove virtual switch
Configuration file:
--------------------
You can specify frequently used options in configuration file of ~/.suseviclientrc
Example of such a config file with comments:
#Default ESXi server to work with
esx_server=\"thessalonike.suse.de\"
#SUSE Studio API user
apiuser=\"studiouser\"
#SUSE Studio API key
apikey=\"studioapikey\"
#Custom SUSE Studio server
studioserver=\"istudio.suse.de\"
All specified directives in config file are easily overridable by the related command control option.
