[SPDK] Add SPDK related option into the QEMU's .XML config file

Hello!
Can someone help me to understand how to add the SPDK's options:
 -chardev socket,id=char0,path=/var/tmp/vhost.0  \
 -device virtio-scsi-pci,id=scsi0

In to the QEMU's .XML file of the VM ?

I see the .XML by the 'virsh edit inner-CentOS8' (where inner-CentOS8 is a nem of the VM), but i cannot uderstand
what are keywords should be used.


Thanks in advance.
