<para>

KVM is the hypervisor we'll be using - we will recover the initial setup
|
|
which has already been done on the hypervisor host and cover installation
|
|
of the agent software, you can use the same steps to add additional KVM
|
|
nodes to your CloudStack environment.

We explicitly are using the management server as a compute node as well,
|
|
which means that we have already performed many of the prerequisite steps
|
|
when setting up the management server, but we will list them here for
|
|
clarity. Those steps are:

You shouldn't need to do that for the management server, of course, but
|
|
any additional hosts will need for you to complete the above steps.

You'll need to ensure that you are in the directory that was created when
|
|
we extracted the the tarball.

You'll be running <filename>./install.sh</filename> again and this time
|
|
choosing <option>A</option> which will install the software necessary for
|
|
managing a KVM node.

<title>KVM Configuration</title>
|
|
<para>
|
|
KVM configuration is relatively simple at only a single item. We need to
|
|
edit the QEMU VNC configuration. This is done by editing
|
|
<filename>/etc/libvirt/qemu.conf</filename> and ensuring the following
|
|
line is present and uncommented.
|
|
<screen>vnc_listen=0.0.0.0</screen>
|
|
</para>
|
|
<para>
|
|
You can now just restart the libvirt daemon by issuing the following command:
|
|
<screen><prompt># </prompt><userinput><command>service</command> libvirt restart</userinput></screen>
|
|
</para>
|
|
<para>
|
|
That concludes our installation and configuration of KVM, and we'll now move to using the CloudStack UI
|
|
for the actual configuration of our cloud.
