Qemu Native to Libvirt XML - qemu

Question

I have created a macos virtual machine using qemu cli everything seems to work great so far. My challenge is to convert it to an libvirt xml now.
I'm trying using this command: virsh domxml-from-native qemu-argv but I get the following error with no other info error: this function is not supported by the connection driver: virConnectDomainXMLFromNative
This is my cli command, I'm using Fedora 31

-device usb-host,hostbus=5,hostport=4.4
I have no clue where to start, the documentation for this function is almost nonexistent

Unfortunately support for the domxml-from-native command has been removed from recentish libvirt, because we found that in practice it was too unreliable and incomplete to be useful.
Your best bet for importing a pre-existing disk image to libvirt is to use the "virt-install" command with its "--import" flag. You can use the various other args to define the disks, NICs, etc.
The only thing I think you'll have trouble with is the "isa-applesmc" device as I don't think libvirt supports that. For that you will need to edit the XML virt-intsall has created, and then add a passthrough option as illustrated here https://libvirt.org/drvqemu.html#qemucommand
