Hello.
I'm running Debian bookworm on my ARM Chromebook,model "xe303c12" and I've recompiled kernel to enable KVM,so now my system sounds like this :
Code:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 12 (bookworm)
Release: 12
Codename: bookworm
$ uname -a
Linux chromarietto 5.4.244-stb-cbe
#8 SMP PREEMPT Sat Aug 19 22:19:32 UTC 2023 armv7l GNU/Linux
$ uname -r

$ kvm-ok

$ qemu-system-arm --version
QEMU emulator version 5.1.0 (v5.1.0-dirty)
Copyright (c) 2003-2020 Fabrice Bellard and the QEMU Project developers
$ python3 --version
Python 3.11.2
I have installed libvirt 9.7.0,qemu 5.1 and virt-manager from source code with the final goal to be able to connect qemu,kvm and libvirt together to virtualize FreeBSD 13.2 for arm 32 bit. If you ask me why I've recompiled everything from source code,my answer will be complicated,but in short terms,for some unknown reason, it reports an error like this :
Code:
"Warning : Failed to set up UEFI /
The Libvirt version does not support UEFI /
Install options are limited"
So,I went for the most complicated route : compiling everything from scratch.
Below I pasted the whole procedure that I've followed,so you can understand well what's wrong.
Code:
$ apt build-dep libvirt
$ git clone https://github.com/libvirt/libvirt.git

$ cd libvirt
$ meson setup build

If I do the opposite way :
$ /usr/local/sbin# virtqemud &
$ /usr/local/sbin# ps ax | grep virtqemu
3041 pts/0 Sl 0:00 virtqemud
$ /usr/local/sbin# libvirtd &
info : libvirt version: 9.7.0 info :

$ /usr/local/sbin# ps ax | grep virtqemu
3041 pts/0 Sl 0:00 virtqemud
$ /usr/local/sbin# ps ax | grep libvirt
nothing
In short terms : when I launch libvirt and then virtqemu,the first one does not close itself,but the second one does it ; when I launch virtqemud and then libvirt,the first one does not close itself,but the second one does it ; so,these two processes are not compatible with each other,but they should run both,otherwise virt-manager will not work at all and I will not be able to run any virtual machine.
