Warning : Failed to set up UEFI / The Libvirt version does not support UEFI / Install options are limited...

Hello to everyone. I'm trying to use qemu 5.1 with virt-manager and libvirt on my ARM chromebook (armhf 32 bit cpu) running with Devuan 4 as host o.s. By default it uses qemu and its dependencies,version 5.2. I remember that I can't use qemu 5.2,because it doesn't have any support for KVM as you can read here : https://lists.gnu.org/archive/html/qemu-devel/2020-09/msg02074.html For this reason,I've compiled qemu 5.1 from source. Below I shown how I have configured everything such as a little piece of compilation messages : # apt install libgtk-3-dev libpulse-dev libgbm-dev libspice-protocol-dev libspice-server-dev libusb-1.0-0-dev libepoxy-dev # cd /usr/share # mv qemu qemu_ # cd /usr/lib # mv qemu qemu_ # cd /usr/lib/arm-linux-gnueabihf # mv qemu qemu_ # cd /usr/lib/ipxe # mv qemu qemu_ # cd /usr/share/bash-completion/completions/ # mv qemu qemu_ # mv qemu-kvm qemu-kvm_ # mv qemu-system-i386 qemu-system-i386_ # mv qemu-system-x86_64 qemu-system-x86_64_ # cd /usr/bin # mv qemu-system-arm qemu-system-arm_ # cp /root/Desktop/qemu-v5.1.0/arm-softmmu/qemu-system-arm /usr/bin # CFLAGS=-Wno-error ./configure --target-list=x86_64-softmmu --enable-opengl --enable-gtk --enable-kvm --enable-guest-agent --enable-spice --audio-drv- list="oss pa" --enable-libusb A little piece of the log messages that I've got from the compilation of qemu 5.1 : https://pastebin.ubuntu.com/p/8DYfgPvhXy/ These are the resulting versions of my frankenstein operation : # virsh version Compiled against library: libvirt 7.0.0 Using library: libvirt 7.0.0 Using API: QEMU 7.0.0 Running hypervisor: QEMU 5.1.0 At this point I've run virt-manager. It has been able to detect qemu,but I get the following error : Warning : Failed to set up UEFI. The Libvirt version does not support UEFI. Install options are limited. Do you have some suggestions to give me to fix this error ? I'm sure to have missed something, thanks. -- Mario.
