In the context of VMware ESX it has been implemented as an API for the ESX host agent. VI Client via the ESX host and/or VirtualCenter, and can report and configure numerous items. Changes made by using this command appear in the VI Client console at normal refresh schedules.
What is vmware-vim-cmd?
Introduced in ESX 3.5 this command is a 'wrapper' for the vimsh shell. It simplifies the command and means that vimsh can be run without having to enter and exit the shell and use previously documented command switches and "quotes".
Why use it?
There is some overlap from current Service Console tools, such as vmware-cmd and esxcfg-* but this API also provides some excellent reporting options and offers new ways to tailor and automate scripting tasks.
The above definitions are the work/findings of Xtravirt and their initial publishing's on VMware vimsh.
Versions of VMware's vimsh:
ESX 3.0.x+
/usr/bin/vimsh -n -e "command"
ESX 3.5+
/usr/bin/vimsh -n -e "command"
/usr/bin/vmware-vimsh "command"
/usr/bin/vmware-vim-cmd "command"
ESX 4.+
/usr/bin/vimsh -n -e "command"
/usr/bin/vmware-vimsh "command"
/usr/bin/vmware-vim-cmd "command"
ESXi 3.5+
/bin/vim-cmd "command"
ESXi 4.0+
/bin/vim-cmd "command"
How to use vimsh?
To see the available commandset for a given "vimsh" release, you just execute the command normally on the shell.You'll be be brought into the interactive shell, you can hit "tab" to see the various options and flags.
When running specific commands on Virtual Machine(s), vimsh requires the internal Virtual Machine Id called "VmId" which needs to be passed as a parameter, the VmId for a given VM can be located when running vmsvc/getallvms as shown below. Unlike the traditional vmware-cmd, where you pass in the .vmx path of a VM, you need to extract the VmId if you're looking to automate/script any tasks using vimsh
General "vimsh" commands for all ESX versions:
Substitute the appropriate "vimsh" for the version of ESX
Find all VMs currently registered to ESX host:
[vimsh|vmware-vimsh|vmware-vim-cmd] vmsvc/getallvms
vimsh -n -e "vmsvc/getallvms"
vmware-vimsh -n -e "vmsvc/getallvms"
vmware-vim-cmd "vmsvc/getallvms"
