I’m vintage, so I have some old machinery but also want to be able to run old software on newer hardware.
TL;DR: Since Apple Silicon (which is based on ARM) uses Intel Emulation for regular Mac binary programs, VMware Fusion# on Mac M* series cannot run Intel based operating systems, after some research there basically were these options:
- use VMware Fusion and run inside a Windows on ARM VM by using
- a dos emulator like DOSBox or DOSBox-X, since modern 64-bit Windows lacks the NTVDM:
Since virtual 8086 mode is not available on non-x86-based processors (more specifically, MIPS, DEC Alpha, and PowerPC) NTVDM is instead implemented as a full emulator in these versions of NT, using code licensed from Insignia’s SoftPC. Up to Windows NT 3.51, only 80286 emulation is available. With Windows NT 4.0, 486 emulation was added.
NTVDM is not included with 64-bit versions of Windows or ARM32 based versions such as Windows RT or Windows 10 IoT Core. The last version of Windows to include the component is Windows 10, as Windows 11 dropped support for 32-bit processors.
- an NTVDM replacement like NTVDMx64 or winevdm (sometimes calles otvdm)
- use a specific emulator like DOSBox-X directly on MacOS
- use a more generic emulator like QEMU based UTM
I have a VMware background on bare metal, Windows and MacOS, so I prefer it over Parallels

Quite a few people already bumped into this the last two days (will add those links later), so today’s confirmation by Broadcom – who have a similar modus operandi as companies like Computer Associates and Symantec were and Idera is now – as of the ESXi death does not come as a surprise.

This is where you can still register for a free ESXi 8 account (until Broadcom kills that):

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
- Original:
- Fork with added VSAN functionality (see [Wayback/Archive] Revisions · Script to rename a virtual machine in ESXi 6):
- My fork of 2:
- 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:
- [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)
- [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 :
- [Wayback/Archive] VMware esxi – Script to clone a VM without vSphere or vCenter. | GrangerX which I put in this gist:
- [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):

- [Wayback/Archive] Script to clone a VM with free VMware ESXi – Rob Pomeroy (again: PowerCLI)

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 :

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:

A while ago, Jilles found out why not to use VirtualBox: [Wayback/Archive] Jilles🏳️🌈 on Twitter: “@jpluimers Ik wil op basis van wat de Arch community schreeuwt; “Virtualbox is stom, als je geen hyper-v gebruikt vraag je om problemen”, HYPER-V maar gaan proberen.” / Twitter
The biggest problem is that VirtualBox seems to be developed ant tested for the happy path, not the failing path.
Which means that when you use it for less common scenarios, it will often fail in mysterious ways.
Back in Running ArchiveTeam Warrior version 3.2 on ESXi, I already mentioned this:
Totally agreeing with Kristian Kohntopp, I do not understand why people use VirtualBox at all: I just run in too much issues like [Archive.is] Kristian Köhntopp on Twitter: “Hint: Wenn die Installation einer Linux-Distro in Virtualbox mit wechselnden, unbekannten Fehlern scheitert, hilft es, stattdessen einmal VMware Workstation oder kvm zu probieren. In meinem Fall hat es dann *jedes* *einzelne* *Mal* mit *demselben* Iso geklappt.”.

A less clickbaity title than most articles today as the below only applies to the VMware hypervisors running on MacOS and Windows.
The last Pwn2Own Zero Day Initiative revealed two major issues that allow a virtual machine to either execute code or read hypervisor memory on the VMware Workstation/Player/Fusion host:
- [Wayback/Archive] NVD – CVE-2023-20869
VMware Workstation (17.x) and VMware Fusion (13.x) contain a stack-based buffer-overflow vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.
- [Wayback/Archive] NVD – CVE-2023-20870
VMware Workstation and Fusion contain an out-of-bounds read vulnerability that exists in the functionality for sharing host Bluetooth devices with the virtual machine.
Both issues have been fixed now, so be sure to deploy the fixes or, if you can’t, apply the workarounds.
