IP configured in a private networks is not used

[desmax74]

Describe the bug
A clear and concise description of what the bug is.

With
On Fedora 41 with
Vagrant Version: 2.4.3
Vagrant-libvirt (0.12.2)
libvirt 10.6.0
a configuration network in the vagrant file like this:

main_server.vm.box = "generic-x64/rhel9" main_server.vm.network "private_network", address: "192.168.121.60"

and the dhcp behaviour is used
and in the log is visible the message

Waiting for domain to get an IP address... ... INFO wait_till_up: Got IP address 192.168.121.127

and a random ip is used, 192.168.121.xxx, instead of the static ip configured

could be related to fog/fog-libvirt@97450dd and is needed a different way to configure a static ip ?

To Reproduce
Configure a private network with an ip, the vagrant instance will receive a different ip

Expected behavior
Is expected to honor the configuration with the static ip configured
instead in the log:
