Another round,another problem. Probably I'm a little bit masochistic
because what I do everyday is to find problems to solve them,like a lot of
computer enthusiasts. This time I'm trying to use qemu 5.1 with
virt-manager and libvirt. Devuan 4 is the host o.s that I'm running on my
ARM chromebook. 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. For this reason,I've compiled qemu 5.1 from source. Below I shown how
I have configured it 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

These are the resulting versions of my frankenstein operation :

root@devuan:/usr/share# 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.
