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:

ESXi shell: appending the parent directory of a script to the path and starting a new shell, even if the script is symlinked

Posted by jpluimers on 2021/10/26

I needed a way to append the directory of a script to the path as all my tool scripts are in there, and I did not want to modify any profile scripts as these might be modified during ESXi upgrade.

First you need the full script filename through readlink then toe parent directory name through dirname:

Note there might be dragons with more symlinks or different shells:

I created the script below. It is not perfect, but for my situation it gets the job done.

If you do not start a new shell, then the export is lost as a new dash shell process is started for each script that runs from the terminal or console.

# cat /opt/bin/append-script-directory-to-path-and-start-new-shell.sh
#!/bin/sh
# Absolute path to this script, e.g. /home/user/bin/foo.sh
# echo "'$0'"
SCRIPT=$(readlink -f "$0")
# Absolute path this script is in, thus /home/user/bin
SCRIPTPATH=$(dirname "$SCRIPT")
# echo Appending to $PATH: $SCRIPTPATH
export PATH=$PATH:$SCRIPTPATH
sh

Via a private message: Agile Rhapsody – Bohemian Rhapsody Parody – Scrum Team Building – Agile … on @YouTube

Posted by jpluimers on 2021/10/26

About half a year ago, someone shard this with me [Archive.is] Jeroen Wiert Pluimers on Twitter: “Via a private message: Agile Rhapsody – Bohemian Rhapsody Parody – Scrum Team Building – Agile …  via @YouTube”.

It is a great video about agile, the manifesto and scrum: spot on.
