@ -3,20 +3,22 @@ How to use VirtualBMC
=====================
For the VirtualBMC tool to operate you first need to create libvirt
domain(s) for example, via ``virsh``. Or you can reuse any of the existing
domains if you do not mind bringing them up and down by way of
managing the simulated servers.
domain(s) for example, via ``virsh``.
The VirtualBMC tool is a client-server system where ``vbmcd`` server
does all the heavy-lifting (speaks IPMI, calls libvirt) while ``vbmc``
client is merely a command-line tool sending commands to the server and
rendering responses to the user.
You should set up your systemd to invoke the *vbmcd* server or you can
just run ``vbmcd`` from command line if you do not need the tool running
persistently on the system. Once the server is up and running, you can use
the ``vbmc`` tool to configure your libvirt domains as if they were physical
hardware servers.

The ``vbmc`` client can only communicate with ``vbmcd`` server if both are
running on the same host. However ``vbmcd`` can manage libvirt domains
remotely.
By this moment you should be able to have the ``ipmitool`` managing
VirtualBMC instances over the network.

Alternatively, libvirt can be configured to ssh into a remote machine
and manage libvirt domain through ssh connection:
$ vbmc add node-1 --port 6230 \
--libvirt-uri qemu+ssh://username@192.168.122.1/system node-1

Binding a network port number below 1025 is restricted and only users
with privilege will be able to start a virtual BMC on those ports.

users keeping their existing server-less workflows, the ``vbmc`` tool
attempts to spawn the ``vbmcd`` piece whenever it figures server is not
running.
