[libvirt-users] Can libvirt set or change the IP address of guest machine

To Whom It May Concern: I use libvirt over one month, I need a function to set the ip address of the guest machine. One can change the guest ip address will be a great appreciation. However, I did not find such a feature in the process of learning libvirt. The purpose of this mail is to ask the experts whether libvirt provide such a feature. If there is no, how can I implement such functionality. Additionally, I already know NAT based network and Routed network can use DHCP, but I want to use an existing host bridge. Best Wishes Harold
