Qemu / Libvirt and Win10 ISO in UEFI mode on Slackware 14.2 host

Hi all, I'm trying to emulate a windows-10 install boot process on a UEFI based virtual machine.
Tried varius attempts with Qemu and OVMF: the machine starts from windows dvd ISO, the "press any key for CD" message appears properly, but then the bios log "Tiano Core" appears again,
and no way to let appear the windows cyan logo and begin its installation wizard; it ends in OVMF EFI Shell.

I tried various qemu boot scripts but with no luck.
I tried using a Bios mode qemu command too, and it works, windows logo appears and install wizard begins properly.

Then tried Virtualbox: in UEFI mode it can boot win10 iso and leads to a complete system install process.

But I'd prefer using qemu so I tried it again by using libvirt and virt-manager, hoping for that more automated solution.
Again it works in BIOS mode.
But if I choose UEFI mode (/usr/share/ovmf-x64/OVMF_CODE-pure-efi.fd) it fails again as explained above:
DVD boot requests to press a key, then Tiano Core logo appears, stays for a while and finally brings to EFI Shell... instead of expected windows logo followed by win install wizard.

My PC is a bit outdated:
- Core 2 Duo E8200 2.66GHz
- Ram 4 GB
- Storage on SSD

Anyway, I'm just trying some tests...

OS: Slackware-14.2 (x86_64 with multilib by AlinBob)

Various packages version:

Code:DL2-2.0.12-x86_64-2_SBo

kernel-firmware-20190821_c0fb3d9-noarch-1
kernel-generic-4.4.190-x86_64-1
kernel-headers-4.4.190-x86-1
kernel-huge-4.4.190-x86_64-1
kernel-modules-4.4.190-x86_64-1
kernel-source-4.4.190-noarch-1

libvirt-4.5.0-x86_64-2_SBo
libvirt-glib-1.0.0-x86_64-1_SBo
libvirt-python-4.5.0-x86_64-1_SBo

qemu-4.1.1-x86_64-1_SBo

virt-manager-1.5.1-x86_64-1_SBo
Anybody there tried a win10 iso with qemu/libvirt in UEFI mode by OVMF?
Should it work on Slackware 14.2?
Where can I look for any return errors?

Thanks in advance!latest?d=yIl2AUoC8zA latest?i=tl4UttmvHgo:LSiowPbLF00:F7zBnMy latest?i=tl4UttmvHgo:LSiowPbLF00:V_sGLiP latest?d=qj6IDK7rITs latest?i=tl4UttmvHgo:LSiowPbLF00:gIN9vFwtl4UttmvHgo
