iVentoy 1.0.16 instantly crashing during iPXE boot attempt (before selection)

[pkx]

I want to deploy iVentoy in my labs to streamline my VM deployment and automate the installation. I've set up a completely new Ubuntu 22.04 new VM:

Code:

root@deipxe:/opt/iventoy# lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 22.04.2 LTS
Release:        22.04
Codename:      jammy

I have configured iVentoy, added a few ISOs, the webinterface is launching, configured it with `ExternalNet`, prepared the DHCP accordingly and everything seems to be pretty much working for now.

iVentoy is also running:

Code:

# ps -ax | grep -i iventoy | grep -v grep
  52829 ?        Ssl    0:01 /opt/iventoy/lib/iventoy

Then I start my VM (in a different subnet), it is then booting just fine:


Just after this screen finishes, the entire VM crashes on ESXi 7.0 U3:

Code:

2023-07-21T00:08:56.817Z In(05) vcpu-0 - Msg_Post: Error
2023-07-21T00:08:56.817Z In(05) vcpu-0 - [msg.efi.exception] The firmware encountered an unexpected exception. The virtual machine cannot boot.

In the iVentoy logs I can only see:

Code:

Interestingly, also iVentoy crashes:

Code:

# ps -ax | grep -i iventoy | grep -v grep
-no output-

Very odd part: I booted up like 30 times now, it worked once until the boot menu (where I can pick the ISO file):

Code:

Booting via SCCM has been working fine, and the 1 attempt worked - so I'd rule out ESXi as the root-cause here.

But it crashes like 99% of my attempts, reproducible. If there're any specific logs I can provide, let me know.

I'd appreciate any assistance here. Thanks!
