Re: [libvirt-users] Reg: Adding "edu" device using XML file
Hello Han,
Thanks for the response. The XML option with qemu:commandline works if the
device is added during the VM creation. But I would like to hot-plug the
device to the running VM. I can add the device using the command line
<virsh qemu-monitor-command --hmp VM-Name device_add edu,id=edu0>
But I would like to add the device using the XML file, like <virsh
attach-device VM-Name xmlfile.xml>. If the XML support is not provided in
libvirt, Is there a document or pointers available to show how to add new
device in libvirt xml code?
Thanks,
Bharath

Hello, edu device is not implemented to libvirt xml. However you can use
it via custom device in libvirt:
Just define a domain like following:
<domain type='qemu'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0
'>
...
<qemu:commandline>
<qemu:arg value='-device'/>
<qemu:arg value='edu'/>
</qemu:commandline>
</domain>
More reference: https://libvirt.org/drvqemu.html#qemucommand
