Hi there, I have used qemu to install FreeBSD 9.2 release, and i can boot it fine with: $ qemu-system-x86_64 -hda images/FreeBSD-9.2-RELEASE-amd64.img I then made virsh aware of my brand new VM (see attached XML), but when i run it via virsh, It hangs after the bootloader whith this message: Booting... CPU doesn't support long mode From the log, here is the generated qemu command: LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/bin:/usr/sbin:/sbin:/bin /usr/bin/qemu-system-x86_64 -name fbsd92-amd64 -S -machine pc-i440fx-1.5,accel=kvm,usb=off -m 512 -realtime mlock=off -smp 1,sockets=1,cores=1,threads=1 -uuid 11ae165e-b8a2-5083-fb77-37c0042725bf -nographic -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/fbsd92-amd64.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/home/christiaga/projects/vms/images/FreeBSD-9.2-RELEASE-amd64.img,if=none,id=drive-ide0-0-0,format=raw -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=1 -netdev tap,fd=24,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:9c:94:3b,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x4 After many attempts, I pinned down the problem. To be able to boot the machine with the above command, I had to remove: * the accel=kvm in -machine * the -S (to "autostart" the VM) And change the -net tap,fd=24 to -net user,id=... So basically, the only thing i would like to tell libvirt is not to use accel=kvm, i guess the FreeBSD kernel is missing some feature (is it this PAE thing?) Does anyone how can i tell libvirt to do that?
Answering myself, replace <domain type='kvm'> with <domain type='qemu'>, virsh undefine <label>, virsh define <xml-file>, et voila! So far it seems to do the job, at least It boots, now i'm configuring the network, finger crossed! ;)
