libvirt users - Jul 2014 - Changing the default qemu path in libvirt

Hi All,

I would like to change the default qemu path in libvirt xml and the changed path
has to be used
while installing VMs using virt-install.

There was a similar question rasied some years back, I could not find the answer
to the same.

Is that possible right now?,
If we have the support already, please point to the same.

Thanks in advance.

Regards,
-Satheesh.
