Hello to everyone. I'm trying to virtualize FreeBSD 13.2 for arm 32 bit on my laptop ARM Chromebook where KVM is enabled,libvirt and virt-manager are installed from the source code and everything work great. The Host OS is Devuan 5. Infact , using these qemu parameters,FreeBSD is able to boot entirely : DISK=/Dati/img/FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img qemu-system-arm \ -enable-kvm -serial stdio \ -m 1024 -M virt -cpu cortex-a15 \ -drive if=pflash,format=raw,unit=0,file=$UEFICODE \ -drive if=pflash,format=raw,unit=1,file=$UEFIVARS \ -drive file=$DISK,media=disk,format=raw \ -device i82559b,netdev=net0,mac="52:54:00:12:34:55" \ -netdev type=user,id=net0 \ -device virtio-gpu-pci \ -usb -device nec-usb-xhci \ -device usb-kbd -device usb-mouse \ -device vmware-svga,id=video0,vgamem_mb=16 *As you can see from this boot log messages :* https://pastebin.ubuntu.com/p/DWggdRRxVv/ *So,this argument is good :* -drive file=$DISK,media=disk,format=raw \ *but these arguments used by libvirt aren't able to boot FreeBSD because the virtio disk attached is not recognized (I also tried with a SATA disk and it is not regognized as well) :* <disk type="file" device="disk"> <driver name="qemu" type="raw"/> <source file="/Dati/img/FreeBSD-13.2-RELEASE-arm-armv7-GENERICSD.img"/> <target dev="vda" bus="virtio"/> <address type="pci" domain="0x0000" bus="0x04" slot="0x00" function="0x0"/> </disk> *as you can see :* [image: Screenshot_2023-09-29_10-44-06.png] What's the difference ? Do you have some vague idea about the reason ? I don't know if the cause is related to libvirt or to FreeBSD,so I'm trying to exclude one of these. -- Mario.
