Script to rename a virtual machine in ESXi 6

Posted by jpluimers on 2024/01/10

I bumped into [Wayback/Archive] Script to rename a virtual machine in ESXi 6: gist.github.com/Gremgoll/8bd91258d71fe895c0d416e2543ca2dc.

Then I forked it with the intent to make usage more clear, as the current usage on my ESXi rig (which has mos VMs not in the root of data stores) is like the bold italic portion here:

[root@X9SRI3F-ESXi:/vmfs/volumes/608be754-f21556ad-1082-0025907d9d5c/VM] vm-rename.sh NVMe980PRO_1TB/VM X9SRI-3F-W10P-NL-OFFICE X9SRI-3F-W10P-NL X9SRI-3F-W10P-NL-OFFICE

All Done. You now need to register X9SRI-3F-W10P-NL-OFFICE to the inventory.

There also was a renaming bug (see the italic line).

I managed to fix both that and added more documentation plus output.

Repositories and code

  1. Original:
  2. Fork with added VSAN functionality (see [Wayback/Archive] Revisions · Script to rename a virtual machine in ESXi 6):
  3. My fork of 2:
  4. My fix:

Code before modifying: [Wayback/Archive] gist.githubusercontent.com/jpluimers/fcc601dd41ac89f601a5174be92c841c/raw/e3683fbb6bdf1e73d65d2b784027c70cf42a5512/vm-rename

Code after modifying: [Wayback/Archive] raw.githubusercontent.com/jpluimers/vm-rename/master/vm-rename.sh.

Yes, that is not in a gist any more (see below why), it is now part of [Wayback/Archive] jpluimers/vm-rename: Script to rename a virtual machine in ESXi 6; fork from https://gist.github.com/jpluimers/fcc601dd41ac89f601a5174be92c841c as [Wayback/Archive] vm-rename/vm-rename.sh at master · jpluimers/vm-rename.

The reason was

Yesterday I described the workaround in Fork Gist to Repo on GitHub – Stack Overflow.

Queries

I found the original via [Wayback/Archive] script esxi rename vmx vmxf and related files – Google Search.

My start was [Wayback/Archive] script esxi duplicate vm and rename vmdk – Google Search which found:

  1. [Wayback/Archive] Renaming a virtual machine and its files in VMware ESXi (1029513) which has a PowerCLI script (that requires Windows to run PowerCLI on)
  2. [Wayback/Archive] Solved: How to clone a VM on a ESXI 6.5 server? – VMware Technology Network VMTN which pointed me to the next Google Search result :
  3. [Wayback/Archive] VMware esxi – Script to clone a VM without vSphere or vCenter. | GrangerX which I put in this gist:
  4. [Wayback/Archive] Script to create Linked Clones on ESXi | RedNectar’s Blog which is great, but way to complicate for my use case. It references a few other cool scripts though, and shows how to use Resource Pools in ESXi (which the Web-UI does not seem to support):

Fork Gist to Repo on GitHub – Stack Overflow

Posted by jpluimers on 2024/01/09

It is not a full fork and misses a few things (including the Gist description), but is the easiest way to clone a gist to a regular GitHub repository.

I needed it because somehow pushing to gists was denied without explanation or real GitHub feedback.

Another reason is that regular GitHub repositories show you way more information about the commits than Gists do.

Thanks [Wayback/Archive] Noitidart for asking and [Wayback/Archive] Bruno Bronosky for answering at [Wayback/Archive] Fork Gist to Repo on GitHub – Stack Overflow:

While migrating VMs, I keep forgetting ESXi likes the text .vmdk file with a binary -flat.vmdk, where Fusion/ Workstation/Player like binary .vmdk file (and how to fix this)

Posted by jpluimers on 2024/01/02

I keep forgetting this, but ESXi likes the text .vmdk file with a binary -flat.vmdk, where Fusion/ Workstation/Player like binary .vmdk file.

Most sites that mention how to solve it love the cryptic parameters like -i  (software developers: when inventing command-line parameters, please use a more descriptive letter for a command) in stead of --clonevirtualdisk), so for instance Migrate VMware Workstation / Fusion VM to ESXi | Ming’s Blog comes up with

[root...] mv Windows-10-64-Enterprise-disk1.vmdk Windows-10-64-Enterprise-disk1.vmdk.fusion
[root...] vmkfstools -i Windows-10-64-Enterprise-disk1.vmdk.fusion Windows-10-64-Enterprise-disk1.vmdk
Destination disk format: VMFS zeroedthick
Cloning disk 'Windows-10-64-Enterprise-disk1.vmdk.fusion'...
Clone: 100% done.

is more readable as

[root...] vmkfstools --clonevirtualdisk Windows-10-64-Enterprise-disk1.vmdk.fusion Windows-10-64-Enterprise-disk1.vmdk

And yes, I wrote about this before, but keep forgetting it applies :

VMware ESXi: shell script to get uuid.bios and all Ethernet generatedAddress MAC address values for all VMs

Posted by jpluimers on 2023/12/28

This is a sort of follow-up on ESXi: listing virtual machines with their IP addresses where we ended with this:

I modified the above script to become this:

#!/bin/sh
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 values:
    #   Powered off
    #   Powered on
    #   Suspended
    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'`
    # 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) [.
    ipAddress=`vim-cmd vmsvc/get.guest ${vmid} | sed -n -E -e '/(vim.vm.GuestInfo) {/,/net = (vim.vm.GuestInfo.NicInfo) [/ s/^ +ipAddress = "(.*)",.*?/1/p'`
    printf "VM with id %3s has power state %-11s and IPv4=%-15s (name = ${name}; vmPathName = ${vmPathName}).n" "${vmid}" "${powerState}" "${ipAddress}"
done

Now the script grew even larger in to vim-cmd-list-all-VMs-with-IPv4-MAC-uuid.sh:

Hello “SMTP Smuggling” information released days before the Holiday season to open source SMTP server teams

Posted by jpluimers on 2023/12/24

Jan Wildeboer was mad for good reasons, though the open source projects didn’t yet seem to publicly have show their real madness, just bits like [Wayback/Archive] oss-security – Re: Re: New SMTP smuggling attack:

I'm a little confused by sec-consult's process here. They identify a
problem affecting various pieces of software including some very widely
deployed open source software, go to the trouble of doing a coordinated
disclosure, but only do that with...looking at their timeline... gmx,
microsoft and cisco?

“SMTP Smuggling” is bad, and big open source SMTP server projects like exim, postfix and sendmail needed to assess and fix/prevent the issue on very short notice: effectively confronting them with a zero-day less than a week between the information got released and the Holiday season.

That gives “deploy on Fridays” a totally different dimension.

How bad? Well, it already managed to reach this Newline – Wikipedia entry:

The standard Internet Message Format[26] for email states: “CR and LF MUST only occur together as CRLF; they MUST NOT appear independently in the body”. Differences between SMTP implementations in how they treat bare LF and/or bare CF characters have led to so-called SMTP smuggling attacks[27].

The crux of the problem is very well described by the “Postfix: SMTP Smuggling” link below: recommended reading, and the middle of [Wayback/Archive] SMTP Smuggling – Spoofing Emails Worldwide | Hacker News

…

TLDR: In the SMTP protocol, the end of the payload (email message) is indicated by a line consisting of a single dot. The line endings normally have to be CRLF, but some MTAs also accept just LF before and/or after the dot. This allows SMTP commands that follow an LF-delimited dot line to be “tunneled” through a first MTA (which requires CRLF and thus considers the commands to be part of the email message) to a second MTA (which accepts LF and thus processes the commands as real commands). For the second MTA, the commands appear to come from the first MTA, hence this allows sending any email that the first MTA is authorized to send. That is, emails from arbitrary senders under the domains associated with the first MTA can be spoofed.

…

Here are some links to keep you busy the next hours/days/weeks:

And the toots linking to background information:
