I managed to have an osx guest running in qemu with the following commands:// create the virtual image$ qemu-img create -f qcow2 mac_hdd.img 35G// .. install osx ...// start the guest$ qemu-system-x86_64 -enable-kvm -m 2048 -cpu core2duo   -machine q35  \ -usb -device usb-kbd -device usb-mouse  \ -device isa-applesmc,osk=XXXXXXXXredactedXXXXXXXX  \ -kernel ./chameleon_svn2360_boot -smbios type=2 \ -device ide-drive,bus=ide.2,drive=MacHDD  -drive id=MacD,if=none,index=2,file=mac_hdd.img \ -netdev user,id=hub0port0 -device e1000-82545em,netdev=hub0port0,id=mac_vnet0 \ -monitor stdioThe guest runs fine; but I also want to able to control it from virt-manager, so I executed the conversion tool like in:$ cat > mac_hdd.args <<EOF// herestring of the argumentsEOF$ virsh  domxml-from-native qemu-argv mac_hdd.args > osx10.8.3.xml// as root# virsh define osx10.8.3.xmlThis generates the following configuration:<domain type='kvm' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>  <name>unnamed</name>  <uuid>7872c6ca-8c58-4eee-801b-b070a2b06abb</uuid>  <memory unit='KiB'>2097152</memory>  <currentMemory unit='KiB'>2097152</currentMemory>  <vcpu placement='static'>1</vcpu>  <os>    <type arch='x86_64' machine='q35'>hvm</type>    <kernel>./chameleon_svn2360_boot</kernel>  </os>  <features>    <acpi/>  </features>  <cpu mode='custom' match='exact'>    <model fallback='allow'>core2duo</model>  </cpu>  <clock offset='utc'/>  <on_poweroff>destroy</on_poweroff>  <on_reboot>restart</on_reboot>  <on_crash>destroy</on_crash>  <devices>    <emulator>qemu-system-x86_64</emulator>    <disk type='file' device='disk'>      <driver name='qemu' type='raw'/>      <source file='./mac_hdd.img'/>      <target dev='hdc' bus='ide'/>      <address type='drive' controller='0' bus='1' target='0' unit='0'/>    </disk>    <controller type='usb' index='0'/>    <controller type='ide' index='0'/>    <controller type='sata' index='0'/>    <controller type='pci' index='0' model='pcie-root'/>    <controller type='pci' index='1' model='dmi-to-pci-bridge'/>    <controller type='pci' index='2' model='pci-bridge'/>    <input type='mouse' bus='ps2'/>    <input type='keyboard' bus='ps2'/>    <graphics type='sdl'/>    <video>      <model type='cirrus' vram='9216' heads='1'/>    </video>    <memballoon model='none'/>  </devices>  <qemu:commandline>    <qemu:arg value='-device'/>    <qemu:arg value='usb-kbd'/>    <qemu:arg value='-device'/>    <qemu:arg value='usb-mouse'/>    <qemu:arg value='-device'/>    <qemu:arg value='isa-applesmc,osk=&quot;XXXXXXredactedXXXXXXXquot;'/>    <qemu:arg value='-smbios'/>    <qemu:arg value='type=2'/>    <qemu:arg value='-device'/>    <qemu:arg value='ide-drive,bus=ide.2,drive=MacHDD'/>    <qemu:arg value='-netdev'/>    <qemu:arg value='user,id=hub0port0'/>    <qemu:arg value='-device'/>    <qemu:arg value='e1000-82545em,netdev=hub0port0,id=mac_vnet0'/>  </qemu:commandline></domain>Unfortunately this does not work (please don't mind the relative paths, I fixed that); as soon I start the vm, I get error cannot find drive MacHDD; I then tried to add an <alias>MacHDD</alias> to the <disk> definition, but still the same error is generated.While if I remove the :  <qemu:arg value='-device'/>  <qemu:arg value='ide-drive,bus=ide.2,drive=MacHDD'/>from the definition, then the vm starts, but fails to boot at the bios screen.Is there a way to accomplish this? I am on Fedora 21 with libvirt-1.2.9.2
