Questions[dhcp](server)

What I'd like to do is to set the guests' network configuration (IP address, subnet, gateway, broadcast address) from the host system. The used network setup is in bridge mode. How can I configure the network from the host rather than configuring the client itself to a static network configuration?

If I execute:

virsh edit vm1

there is a <network> block as well and I tried to configure the network interface from there, but unfortunately the guest VM doesn't seem to use it and as such is offline to the network (since it uses automatic network configuration only)... Guest VMs are both, Linux and Windows based. Any help would be highly appreciated.

This is a Canonical Question about Redundant DHCP Servers.

Is it possible to have more than one DHCP server on the same LAN? What are the implications of doing this?

1. What happens if there is more than one DHCP server available? How do my clients know which one to use?
2. How can I have DHCP servers supplying addresses to more than one subnet\network segment?
3. How can I configure multiple DHCP servers to supply addresses for the same subnet.

Is there a simple ping-like command to test whether a DHCP service is running on a network? ...on Linux

The environment is Debian, although the answer will apply to all distributions.

What's the best approach towards determining if I have a rogue DHCP server inside my network?

I'm wondering how most admins approach these kinds of problems. I found DHCP Probe through searching, and thought about trying it out. Has anyone had experience with it? (I would like to know before taking the time to compile it and install).

Do you know any useful tools or best-practices towards finding rogue DHCP servers?
