--> <title>KVM Setup and installation</title>
|
|
<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. <xref linkend="sect-Runbook-Management-extraction" />

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.
