[libvirt] Parse commandline for -device option
Hi Maintainers,
Currently libvirt could only parse commandline for several legacy devices.
For example,
-pcidevice: qemuParseCommandLinePCI()
-usbdevice: qemuParseCommandLineUSB()
It also provides test cases for host device assignment.
DO_TEST("hostdev-usb-address");
DO_TEST("hostdev-pci-address");
But for other hostdev with -device option, it failed to convert into <hostdev> tag.
-device vfio-pci,host=06:12.5,id=hostdev0,bus=pci.0,addr=0x3
$ virsh domxml-from-native qemu-argv kvm.args >kvm.xml
<qemu:commandline>
<qemu:arg value='-device'/>
<qemu:arg
value='vfio-pci,host=06:12.5,id=hostdev0,bus=pci.0,addr=0x3'/>
</qemu:commandline>
Expected XML file should like below:
<hostdev mode='subsystem' type='pci' managed='yes'>
<driver name='vfio'/>
<source>
<address domain='0x0000' bus='0x06' slot='0x12'
function='0x5'/>
</source>
</hostdev>
Maybe it is not very critical.
Is it complicated to add support to -device option in function qemuParseCommandLine()?
Do you have any thought or plan about it?
Best Regards,
Olivia
