Srs.
Let me put my two cents.
Who is facing dificulties to install Cnmaestro OnPrem 6.0 into proxmox, here some details can help.
First import the OVA into proxmox using Import Option on the datastore.
After that import the vm, in this step pay attention to change processor to host (don´t forget check if your processor have a specific flag AVX2 required for mongoDB Works).
Adjust the Memory and cores.
Change Network interface to Virtio.
After finish the import, go to hardware tag and change video card from standard to Virtio with 32mb (Ubuntu 24.04 have problems with standard video).
Change the disk controler from LSI to SCSI SINGLE (Is necessary to boot).
Enjoy.
