[libvirt-users] set a different default gateway in an isolated network



Hello,

I would like to set a specify default gateway for my VMs. However I’m not succeeding 

Here after is the isolated lan, where I added the statement   <route address='10.0.0.0' prefix='8' gateway='10.10.0.7’/> where my aim is to route to the 10.10.0.7 

What should I do , to make it works ?

Thanks

When looking on the VM (guest) the route is not correctly set
