Without this setting, an idle FreeBSD <application>Parallels</application> guest will use roughly 15% of the CPU of a single processor <trademark class="registered">iMac</trademark>. After this change the usage will be closer to 5%.

After the FreeBSD virtual machine has been created, FreeBSD can be installed on it. This is best done with an official FreeBSD <acronym>CD</acronym>/<acronym>DVD</acronym> or with an <acronym>ISO</acronym> image downloaded from an official <acronym>FTP</acronym> site. Copy the appropriate <acronym>ISO</acronym> image to the local <trademark class="registered">Mac</trademark> filesystem or insert a <acronym>CD</acronym>/<acronym>DVD</acronym> in the <trademark class="registered">Mac</trademark>'s <acronym>CD-ROM</acronym> drive. Click on the disc icon in the bottom right corner of the FreeBSD <application>Parallels</application> window. This will bring up a window that can be used to associate the <acronym>CD-ROM</acronym> drive in the virtual machine with the <acronym>ISO</acronym> file on disk or with the real <acronym>CD-ROM</acronym> drive.

Once this association with the <acronym>CD-ROM</acronym> source has been made, reboot the FreeBSD virtual machine by clicking the reboot icon. <application>Parallels</application> will reboot with a special <acronym>BIOS</acronym> that first checks if there is a <acronym>CD-ROM</acronym>.
_ external ref='virtualization/parallels-freebsd10' md5='__failed__'
In this case it will find the FreeBSD installation media and begin a normal FreeBSD installation. Perform the installation, but do not attempt to configure <application>Xorg</application> at this time.

When the installation is finished, reboot into the newly installed FreeBSD virtual machine.

Configuring FreeBSD on <application>Parallels</application>
After FreeBSD has been successfully installed on <trademark class="registered">Mac OS</trademark> X with <application>Parallels</application>, there are a number of configuration steps that can be taken to optimize the system for virtualized operation.
Set Boot Loader Variables
The most important step is to reduce the <option>kern.hz</option> tunable to reduce the CPU utilization of FreeBSD under the <application>Parallels</application> environment. This is accomplished by adding the following line to <filename>/boot/loader.conf</filename>:
kern.hz=100
Without this setting, an idle FreeBSD <application>Parallels</application> guest will use roughly 15% of the CPU of a single processor <trademark class="registered">iMac</trademark>. After this change the usage will be closer to 5%.
Create a New Kernel Configuration File
All of the SCSI, FireWire, and USB device drivers can be removed from a custom kernel configuration file. <application>Parallels</application> provides a virtual network adapter used by the <citerefentry><refentrytitle>ed</refentrytitle><manvolnum>4</manvolnum></citerefentry> driver, so all network devices except for <citerefentry><refentrytitle>ed</refentrytitle><manvolnum>4</manvolnum></citerefentry> and <citerefentry><refentrytitle>miibus</refentrytitle><manvolnum>4</manvolnum></citerefentry> can be removed from the kernel.
Configure Networking
The most basic networking setup uses DHCP to connect the virtual machine to the same local area network as the host <trademark class="registered">Mac</trademark>. This can be accomplished by adding <literal>ifconfig_ed0="DHCP"</literal> to <filename>/etc/rc.conf</filename>. More advanced networking setups are described in <xref linkend="advanced-networking"/>.
FreeBSD as a Guest on <application>Virtual PC</application> for <trademark class="registered">Windows</trademark>
<application>Virtual PC</application> for <trademark class="registered">Windows</trademark> is a <trademark class="registered">Microsoft</trademark> software product available for free download. See this website for the <link xlink:href="http://www.microsoft.com/windows/downloads/virtualpc/sysreq.mspx">system requirements</link>. Once <application>Virtual PC</application> has been installed on <trademark class="registered">Microsoft</trademark> <trademark class="registered">Windows</trademark>, the user can configure a virtual machine and then install the desired guest operating system.
Installing FreeBSD on <application>Virtual PC</application>
The first step in installing FreeBSD on <application>Virtual PC</application> is to create a new virtual machine for installing FreeBSD. Select <guimenuitem>Create a virtual machine</guimenuitem> when prompted:
_ external ref='virtualization/virtualpc-freebsd1' md5='__failed__'
_ external ref='virtualization/virtualpc-freebsd2' md5='__failed__'
Select <guimenuitem>Other</guimenuitem> as the <guimenuitem>Operating system</guimenuitem> when prompted:
_ external ref='virtualization/virtualpc-freebsd3' md5='__failed__'
Then, choose a reasonable amount of disk and memory depending on the plans for this virtual FreeBSD instance. 4GB of disk space and 512MB of RAM work well for most uses of FreeBSD under <application>Virtual PC</application>:
_ external ref='virtualization/virtualpc-freebsd4' md5='__failed__'
_ external ref='virtualization/virtualpc-freebsd5' md5='__failed__'
