[libvirt] 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
