Hi everyone,
Thank you for your answers. First of all, I made a mistake : the HP-UX 10.20 kernel (vmunix) is in the /stand (not /boot) filesystem. I tried replacing /stand of the physical machine iso image with the /stand filesytem of the emulated B160L because I supposed that drivers are linked with the vmunix kernel. Maybe it's false. Furthermore, the /dev tree is important for dealing with the drivers. I will continue to search for which files are hardware related. Maybe someone has done this research before ?

Maybe at some point a 64-bit capable system, e.g. C3000, and maybe an older 32-bit system, e.g. 715/64. For the 64bit system additions to the emulated firmware and additional 64-bit qemu support is necessary, and for the 715/64 we need an additional NCR710 SCSI driver. Both are lots of work. The B180L is exactly the same as the B160L, with just a faster CPU: <https://www.openpa.net/systems/hp-visualize_b132l_b160l_b180l.html> https://www.openpa.net/systems/hp-visualize_b132l_b160l_b180l.html > * Or, what changes should I make to my iso image to do it usable ?

I could imagine that your physical machines have different SCSI controller cards which are used by HP-UX, and which aren't emulated in qemu yet. That's maybe why qemu can't boot your already installed images. If you post the output I maybe can give more info. > Helge is the one that did all the hw support, I just did the CPU. > There are no real plans to do another machine.
