Nested Esxi 7 on Proxmox 7.3

[usermx01]

I'm having trouble to deploy VMs in a nested environment with Esxi 7 on Proxmox 7.3. When I power on the VM (Alpine) within esxi, boot always fails.
Im using the mini pc M600 with the Ryzen 6900hx CPU. Nesting has been enabled in proxmox and do work ubuntu/debian as nested hypervisor.

Configuration in proxmox for esxi is:


Configuration in esxi for the vm:


However the logs in esxi when I power on the VM show invalid VMCB the following:

Anyone has some experience on how to solve this kind of problem?

The above setup in particular I never tried, but more than once I experienced problem with nested virtualization when having an AMD Ryzen CPU in host. Try using different kernels in host and/or specify a specific CPU as well as SVM flag, in one case the following (adding in .conf file) helped:

args: -cpu Opteron_G3,+svm

Thanks for the feedback but unfortunately still no joy after trying several AMD processors in the ARGS. Maybe something else is expected at esxi side besides the same flag that the Ryzen and proxmox are not reporting.

Have you tried older versions?

Currently only 7.x. For the iGPU seems Kernel 5.19 is the oldest that works properly with the one in the 6900hx after installing AMD drivers.
