VFrontDe/ESXi-Customizer-PS: PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized VMware ESXi installation images

Posted by jpluimers on 2021/11/30

On my list of things to try, as it allows me to have an ISO at hand in case I ever need to quickly re-install a machine to the current patch level (for instance when the USB boot stick breaks down: these things happen in reality): [Wayback] VFrontDe/ESXi-Customizer-PS: PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized VMware ESXi installation images

ESXi-Customizer-PS is a Powershell script that greatly simplifies and automates the process of creating fully patched and customized ESXi 5.x and 6.x installation ISOs using the VMware PowerCLI ImageBuilder module/snapin.

…

Requirements

A Windows computer (XP or newer) with Powershell 2.0 or newer

VMware PowerCLI version 5.1 or newer

…

You can get the code from [Wayback] ESXi-Customizer-PS/ESXi-Customizer-PS.ps1 at master · VFrontDe/ESXi-Customizer-PS.

The old site (which still has most of the documentation) can be reached at two places:

[Wayback] esxi-customizer-ps.v-front.de which redirects to
[Wayback] www.v-front.de/p/esxi-customizer-ps.html

A video showing how to use it is below the signature.

The above links via [Wayback] Custom ESXi ISO with ne1000 driver for install on Intel NUC Frost Canyon – seanwalsh.dev.

Oh: you can check if you have a PXE, USB or HDD installation of ESXi via the steps here: Determining the ESXi installation type (2014558) | VMware KB.

Some bash parameter propagation links that hopefully will work with ash/dash too

Posted by jpluimers on 2021/10/27

For my link archive; I started with [Wayback] dash get all parameters quoted – Google Search:

[Wayback] Handling positional parameters [Bash Hackers Wiki] has this handy table:

Parameter(s) Description

$0 the first positional parameter, equivalent to argv[0] in C, see the first argument

$FUNCNAME the function name (attention: inside a function, $0 is still the $0 of the shell, not the function name)

$1 … $9 the argument list elements from 1 to 9

${10} … ${N} the argument list elements beyond 9 (note the parameter expansion syntax!)

$* all positional parameters except $0, see mass usage

$@ all positional parameters except $0, see mass usage

$# the number of arguments, not counting $0

These positional parameters reflect exactly what was given to the script when it was called.

Option-switch parsing (e.g. -h for displaying help) is not performed at this point.

See also the dictionary entry for “parameter”.

[Wayback] Handling positional parameters: mass usage [Bash Hackers Wiki] has this summary table:

Syntax Effective result

$* $1 $2 $3 … ${N}

$@ $1 $2 $3 … ${N}

"$*" "$1c$2c$3c…c${N}"

"$@" "$1" "$2" "$3" … "${N}"
[Wayback] Parameter expansion [Bash Hackers Wiki]
The elaborate answer to [Wayback] How to pass all arguments passed to my bash script to a function of mine? – Stack Overflow by [Wayback] User Gordon Davisson – Stack Overflow of which the first part is:
The $@ variable expands to all command-line parameters separated by spaces. Here is an example.
```
abc "$@"
```
When using $@, you should (almost) always put it in double-quotes to avoid misparsing of arguments containing spaces or wildcards (see below). This works for multiple arguments. It is also portable to all POSIX-compliant shells.

It is also worth nothing that $0 (generally the script’s name or path) is not in $@.

The Bash Reference Manual Special Parameters Section says that $@ expands to the positional parameters starting from one. When the expansion occurs within double quotes, each parameter expands to a separate word. That is "$@" is equivalent to "$1" "$2" "$3"....
Last part of the [Wayback] Accessing bash command line args $@ vs $* – Stack Overflow answer by [Wayback] Serge Stroobrandt:

If the arguments are to be stored in a script variable and the arguments are expected to contain spaces, I wholeheartedly recommend employing a "$*" trick with the input field separator set to tab IFS=$'\t' [Wayback].

and comment by Serge as well:

Here is [Wayback] an example, which includes quoted input. The input also matters!

Parameter(s)	Description
`$0`	the first positional parameter, equivalent to `argv[0]` in C, see the first argument
`$FUNCNAME`	the function name (attention: inside a function, `$0` is still the `$0` of the shell, not the function name)
`$1 … $9`	the argument list elements from 1 to 9
`${10} … ${N}`	the argument list elements beyond 9 (note the parameter expansion syntax!)
`$*`	all positional parameters except `$0`, see mass usage
`$@`	all positional parameters except `$0`, see mass usage
`$#`	the number of arguments, not counting `$0`

Syntax	Effective result
`$*`	`$1 $2 $3 … ${N}`
`$@`	`$1 $2 $3 … ${N}`
`"$*"`	`"$1c$2c$3c…c${N}"`
`"$@"`	`"$1" "$2" "$3" … "${N}"`

[Wayback] Propagate all arguments in a bash shell script – Stack Overflow (thanks [Wayback] Sdaz MacSkibbons for the answer and [Wayback] Ilan Schemoul to make it understandable by applying proper naming of the script files):

Use "$@" instead of plain $@ if you actually wish your parameters to be passed the same.

Observe:

$ cat no_quotes.sh

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:

- [Wayback] string – bash : Bad Substitution – Stack Overflow
```
me@pc:~$ readlink -f $(which sh)
/bin/dash
```
  By [Wayback] Vanni Totaro.
- [Wayback] shell – Getting parent’s directory name by piping the results of dirname to basename in a Bash script – Stack Overflow
```
# echo 'test/90_2a5/Windows' | xargs dirname | xargs
basename90_2a5
```
  By [Wayback] Rafael.

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

VMware ESXi has 2 bootbanks; with some luck the second contains your old ESXi version

Posted by jpluimers on 2021/10/19

Just in case I ever need this again:

[Wayback] VMware Knowledge Base: Reverting to a previous version of ESXi (1033604)
1. In the console screen of the ESXi host, press Ctrl+Alt+F2 to see the Direct Console User Interface (DCUI) screen.
2. Press F12 to view the shutdown options for the ESXi host.
3. Press F11 to reboot.
4. When the Hypervisor progress bar starts loading, press Shift+R. You will see the warning:
```
Current hypervisor will permanently be replaced
with build: X.X.X-XXXXXX. Are you sure? [y/n]
```
5. Press Y to roll back the build.
6. Press Enter to boot.
[Wayback] Downgrade ESXi 6.5 from update 3 to update 2 – VMware Technology Network VMTN; when out of luck:
- This is not my case.As I mentioned, I don’t have altbootbank with update 2. This is because after update 3, I also installed the latest patch.So both bootbanks now have update 3.Is there any other option for me. Can I just install update 2 again so it will overwrite everything? Or it is impossible?
- Backup ESXi configurations and reinstall it without overwriting VMFS.

“fixing” ESXi “rsync error: error allocating core memory buffers (code 22) at util2.c(106) [sender=3.1.2]”

Posted by jpluimers on 2021/08/30

Reminder to self: create a static ESXi binary for a recent rsync release.

Quite a few people have bumped into rsync erroring out with “large” sets of files (where large can be as low as ~1000), like for instance Tj commenting on my post “ESXi 5.1 and rsync – damiendebin.net.”:

ERROR: out of memory in receive_sums [sender] │······
rsync error: error allocating core memory buffers (code 22) at util2.c(102) [sender=3.1.1] │······
rsync: [generator] write error: Broken pipe (32) │······

I bumped into this myself as well, even when updating from rsync 3.1.0 to 3.1.2.

There are various static rsync for ESXi around. Just a few of them for completeness:

3.1.0: ESXi 5.1 and rsync – damiendebin.net. (how to download the build by Damien Debin from http://damiendebin.net and how to create the right XML firewall settings from his [Wayback] gist)

3.1.2: [Wayback] DOWNLOADS – bachmann-lan.de via [Wayback] VMware ESXi 5.1 rsync 3.0.9 statically linked binary erstellen – bachmann-lan.de

3.1.3: [Wayback/Archive.is] noelmartinon/vmtools: Tools for VMware ESXi to use in ESXi which pointed at the wrong binary link, so I archived the right one in the Wayback machine.

There is also 3.0.9 (via [Wayback] VMware ESXi 5.1 rsync 3.0.9 statically linked binary erstellen – bachmann-lan.de), but it has a VMFS bug ([Wayback] 8177 – Problems with big sparsed files) as per [Wayback] ESXi 5.1 and rsync – damiendebin.net.)

The good news is that it is fixed in 3.2.2 as a user-configurable setting, but since there is no ESXi build yet (see reminder above)…

Anyway: [Wayback] 12769 – error allocating core memory buffers (code 22) depending on source file system

Wayne Davison 2020-06-26 03:56:35 UTC

I fixed the allocation args to be size_t values (and improved a bunch of allocation error checking while I was at it).

I then added an option that lets you override this allocation sanity-check value. The default is still 1G per allocation, but you can now specify a much larger value (up to "--max-alloc=8192P-1").

If you want to make a larger value the default for your copies, export RSYNC_MAX_ALLOC in the environment with the size value of your choice.

Committed for release in 3.2.2.

This is what happens with 3.1.2 and 3.1.3:

time rsync -aiv --info=progress2 --progress --partial --existing --inplace /vmfs/volumes/Samsung850-2TB-S3D4NX0HA01043L/ Samsung850-2TB-S3D4NX0HA01043L/

I was lucky that [Wayback] “rsync error: error allocating core memory buffers” protocol version “3.1.2” – Google Search got me a result so quickly: add a --protocol-29 and you are set.

The first result (Wayback has the results reversed from what got) didn’t fix it. The second did.

[Wayback] 225761 – net/rsync long path causes buffer overflow (update to 3.1.3)
[Wayback/Archive.is] AIX Open Source – IBM Power Systems Community: rsync out of memory

As a work around, I added “--protocol=29” to one of our servers that was consistently failing with “ERROR: out of memory in flist_expand [receiver]” “rsync error: error allocating core memory buffers (code 22) at util2.c(105) [receiver=3.1.3]” in rsync-3.1.3-2.ppc

I read the man page and started experimenting with the protocol version until I lowered it enough to get it to work consistently.

The problem might be that running on the ESXi gives you limited memory, but then some 10k files should not use more than like half a megabyte of memory.

Sometime I will dig deeper into the protocol version differences, for now a list of files I think will be relevant for that (mainly look for protocol_version):

Some web pages mentioning the --protocol option and might give me more insight in the protocol differences:

With --protocol=29, time estimation is way off, but there are no errors:

time rsync -aiv --info=progress2 --progress --partial --existing --inplace --protocol=29 /vmfs/volumes/Samsung850-2TB-S3D4NX0HA01043L/ Samsung850-2TB-S3D4NX0HA01043L/

Windows on VMware ESXi: fixing “Unknown USB Device” or “The USB device returned an invalid USB device descriptor”

Posted by jpluimers on 2021/08/27

Sometimes, the Windows device manager shows any of the below errots for an USB 3.x device that is physically connected to the ESXi host and passes through a VM (via a virtual USB controller and virtual USB device).

This solution usually works: use a USB 2.0 cable instead of a USB 3.x cable.

If it doesn’t work, then the solutions are the same as when this happens in a pure physical solution:

In my case, I needed a USB connection, because it is the only way to reset a Fujitsu ScanSnap scanner to correct WiFi settings after it gets confused (which happens a few times per year).

ESXi: finding unmounted VMFS volumes

Posted by jpluimers on 2021/08/26

Sometimes, especially when ESXi thinks a volume is bad, but the ESXi S.M.A.R.T. logging does not indicate so, it boots without mounting some of the VMFS volumes as datastores.

It took me a while to find the right command to list those, but I’m glad I found it:

NVMe and SATA health data on ESXi: some links to investigate

Posted by jpluimers on 2021/08/25

(Edit 20221202: added one more link on “REALLOCATED SECTOR CT below threshold”)

Somehow, health data of my NVMe and SATA drives do not show up as health information on the web-ui of my ESXi playground rig.

So far, I noticed that ESXi runs a smartd, but does not ship with a smartctl, nor health data ends up in the web user interface. So you cannot see the state of NVMe and SATA devices easily.

Still these devices deteriorate over time and afterwards die, so below are some links to investigate later.

Goal is to use my own thresholds to set warning and error levels.

Some log entries:
