[libvirt-users] how to modify virsh vm start script

[Ady Wahyudi Paundu]

I use libvirt to manage a QEMU/KVM system. Starting a VM only by using
  > virsh start vmname
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
