Hello.
I'm running Debian bookworm on my ARM Chromebook,model "xe303c12" and
I've recompiled the kernel (5.4) to enable KVM,so now my system sounds like this :$ lsb_release -a
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.
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 5.4.244-stb-cbe $ kvm-ok INFO: /dev/kvm exists KVM acceleration can be used $ 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

# lsmod | grep kvm no errors (
# virsh --connect qemu:///system capabilities | grep baselabel
<baselabel type='kvm'>+1002:+1002</baselabel>
<baselabel type='qemu'>+1002:+1002</baselabel>
The error that I'm not able to fix is the following one :root@chromarietto:~# virsh domcapabilities --machine virt --emulatorbin /usr/local/bin/qemu-system-arm 2023-08-29 10:17:59.110+0000: 1763: error : virHostCPUGetKVMMaxVCPUs:1228 : KVM is not supported on this platform: Function not implemented ; error: failed to get emulator capabilities error: KVM is not supported on this platform: Function not implemented
and this is the log that I've got when I ran libvirtd with the debug option enabledroot@chromarietto:~# libvirtd --debug

Does anyone know how to fix that error ?
