ubuntu – 将QEMU命令行参数转换为libvirt域xml

我很难将此QEMU命令转换为libvirt域
XML

qemu-system-x86_64 -enable-kvm \
-m 3072 \
-cpu core2duo \
-machine q35 \
-smp 2 \
-usbdevice keyboard \
-usbdevice mouse \
-vga std \
-device isa-applesmc,osk="${osx_osk_key}" \
-kernel "${chameleon_file_path}" \
-device ide-drive,bus=ide.2,drive=MacHDD \
-drive id=MacHDD,if=none,cache=none,file="${vm_hdd_img_file_path}"
-netdev user,id=hub0port0 \
-device virtio-net,netdev=hub0port0,id=eth0

如果我从一个终端(Ubuntu 14.10)调用它,它可以完美地运行,但是对于MacHDD设备,virsh domxml-from-native qemu-argv失败并出现此错误:

error: internal error: missing index/unit/bus parameter in drive 'id=MacHDD,if=none,cache=none,file="${vm_hdd_img_file_path}"'

(注意:当然我尝试使用实际路径代替变量,同样的错误 – 如果我删除最后两个args,它将其转换为域XML,即使包含变量)

我该怎么解决这个问题?或者什么是域xml中最后两个args的等价物? (尝试了很多不同的组合,但无法使用libvirt / virsh)

为了记录,这是我在没有-device -drive的情况下运行virsh的domain-from-native命令

<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>

    <qemu:arg value='-device'/>
    <qemu:arg value='virtio-net,netdev=hub0port0,id=eth0'/>
  </qemu:commandline>
</domain>

但我无法弄清楚在这种情况下什么是-device -drive的等价物,我无法从这个域xml创建一个VM.

即使没有MacHDD -device和-drive,当我尝试使用$virsh创建VM时,我也会收到此错误

error: Failed to create domain from libvirt.xml
error: internal error: cannot load AppArmor profile 'libvirt-38cafecb-4774-4590-83eb-e576a79aab93'

最佳答案 TBH我对libvirt并不熟悉,但它不会是这样的:

   <disk type='file' device='disk'>
     <source file='/path/to/image.img'/>
     <target dev='hda' bus='ide'/>
   </disk>
