ESXi: listing virtual machines with their IP addresses

Posted by jpluimers on 2021/10/26

This is sort of a follow-up on VMware ESXi console: viewing all VMs, suspending and waking them up: part 4 which already gave part of the configuration details of all the configured VMs.

Back then, we ended with this:

List the vmid values, power status and name of all VMs

Back to the listing script vim-cmd-list-all-VMs.sh:

#!/bin/sh
# https://wiert.me/2021/04/29/vmware-esxi-console-viewing-all-vms-suspending-and-waking-them-up-part-4/
vmids=`vim-cmd vmsvc/getallvms | sed -n -E -e "s/^([[:digit:]]+)\s+((\S.+\S)?)\s+(\[\S+\])\s+(.+\.vmx)\s+(\S+)\s+(vmx-[[:digit:]]+)\s*?((\S.+)?)$/\1/p"`
for vmid in ${vmids} ; do
    powerState=`vim-cmd vmsvc/power.getstate ${vmid} | sed '1d'`
    name=`vim-cmd vmsvc/get.config ${vmid} | sed -n -E -e '/\(vim.vm.ConfigInfo\) \{/,/files = \(vim.vm.FileInfo\) \{/ s/^ +name = "(.*)",.*?/\1/p'`
    vmPathName=`vim-cmd vmsvc/get.config ${vmid} | sed -n -E -e '/files = \(vim.vm.FileInfo\) \{/,/tools = \(vim.vm.ToolsConfigInfo\) \{/ s/^ +vmPathName = "(.*)",.*?/\1/p'`
    echo "VM with id ${vmid} has power state ${powerState} (name = ${name}; vmPathName = ${vmPathName})."
done

It uses vim-cmd vmsvc/getallvms, vim-cmd vmsvc/power.getstate and vim-cmd vmsvc/get.config with some sed and a for loop from dash to generate a nice list of information.

A long time ago, I already figured out that vim-cmd vmsvc/get.guest # gives all guest information including network information for a running VM that has either VMware Tools or open-vm-tools running (see VMware ESXi console: viewing all VMs, suspending and waking them up: part 3 for the difference between these two tools).

A full output of a sample VM is below the signature.

There are a few places that have the LAN ipAddress. For now, I choose to use only the IPv4 main address from ipAddress, which is in between (vim.vm.GuestInfo) { and net = (vim.vm.GuestInfo.NicInfo) [.

I modified the above script to become this:

linux – How can I find all hardlinked files on a filesystem? – Super User

[WayBack] linux – How can I find all hardlinked files on a filesystem? – Super User

use the following line (for sure you have to replace /PATH/FOR/SEARCH/ with whatever you want to search):

find /PATH/FOR/SEARCH/ -xdev -printf '%i\t%n\t%p\n' | fgrep -f <(find . -xdev -printf '%i\n' | sort -n | uniq -d) | sort -n

this scans the filesystem only once, shows inode, number of hardlinks and path of files with more than one hardlink and sorts them according to the inode.

if you are annoyed by error messages for folders you aren’t allowed to read, you can expand the line to this:

find /PATH/FOR/SEARCH/ -xdev -printf '%i\t%n\t%p\n' 2> /dev/null | fgrep -f <(find . -xdev -printf '%i\n' 2> /dev/null | sort -n | uniq -d) | sort -n

It uses these commands:
