What I want to know is how to add an option to virsh vm's start
script, in my case I want to add QEMU logging option (-d and -D). I
can see from
 > ps aux | grep qemu
that current VM started using virsh not including those options


This is not supported in our XML, but you can use passthrough of
arbitrary options:

http://libvirt.org/drvqemu.html

E.g.:

<domain type='qemu'
xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
...
 <qemu:commandline>
   <qemu:arg value='-d'/>
   <qemu:arg value='cpu'/>
 </qemu:commandline>
 ...
</domain>
