Parallels Desktop for Mac® is a commercial software product available for Intel® based Apple® Mac® computers running Mac OS® 10.4.6 or higher. FreeBSD is a fully supported guest operating system. Once Parallels has been installed on Mac OS® X, the user must configure a virtual machine and then install the desired guest operating system.
The first step in installing FreeBSD on Parallels is to create a new virtual machine for installing FreeBSD. Select as the when prompted:
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 Parallels:
Select the type of networking and a network interface:
Save and finish the configuration:
After the FreeBSD virtual machine has been created, FreeBSD can be installed on it. This is best done with an official FreeBSD CD/DVD or with an ISO image downloaded from an official FTP site. Copy the appropriate ISO image to the local Mac® filesystem or insert a CD/DVD in the Mac®'s CD drive. Click on the disc icon in the bottom right corner of the FreeBSD Parallels window. This will bring up a window that can be used to associate the CDROM drive in the virtual machine with the ISO file on disk or with the real CDROM drive.
Once this association with the CDROM source has been made, reboot the FreeBSD virtual machine by clicking the reboot icon. Parallels will reboot with a special BIOS that first checks if there is a CDROM.
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 Xorg at this time.
When the installation is finished, reboot into the newly installed FreeBSD virtual machine.
After FreeBSD has been successfully installed on Mac OS® X with Parallels, 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
kern.hztunable to reduce the CPU utilization of FreeBSD under the Parallels environment. This is accomplished by adding the following line to/boot/loader.conf:kern.hz=100Without this setting, an idle FreeBSD Parallels guest will use roughly 15% of the CPU of a single processor iMac®. 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. Parallels provides a virtual network adapter used by the ed(4) driver, so all network devices except for ed(4) and miibus(4) 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 Mac®. This can be accomplished by adding
ifconfig_ed0="DHCP"to/etc/rc.conf. More advanced networking setups are described in Chapter 30, Advanced Networking.
Virtual PC for Windows® is a Microsoft® software product available for free download. See this website for the system requirements. Once Virtual PC has been installed on Microsoft® Windows®, the user can configure a virtual machine and then install the desired guest operating system.
The first step in installing FreeBSD on Virtual PC is to create a new virtual machine for installing FreeBSD. Select when prompted:
Select as the when prompted:
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 Virtual PC:
Save and finish the configuration:
Select the FreeBSD virtual machine and click , then set the type of networking and a network interface:
After the FreeBSD virtual machine has been created, FreeBSD can be installed on it. This is best done with an official FreeBSD CD/DVD or with an ISO image downloaded from an official FTP site. Copy the appropriate ISO image to the local Windows® filesystem or insert a CD/DVD in the CD drive, then double click on the FreeBSD virtual machine to boot. Then, click and choose on the Virtual PC window. This will bring up a window where the CDROM drive in the virtual machine can be associated with an ISO file on disk or with the real CDROM drive.
Once this association with the CDROM source has been made, reboot the FreeBSD virtual machine by clicking and . Virtual PC will reboot with a special BIOS that first checks for a CDROM.
In this case it will find the FreeBSD installation media and begin a normal FreeBSD installation. Continue with the installation, but do not attempt to configure Xorg at this time.
When the installation is finished, remember to eject the CD/DVD or release the ISO image. Finally, reboot into the newly installed FreeBSD virtual machine.
After FreeBSD has been successfully installed on Microsoft® Windows® with Virtual PC , 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
kern.hztunable to reduce the CPU utilization of FreeBSD under the Virtual PC environment. This is accomplished by adding the following line to/boot/loader.conf:kern.hz=100Without this setting, an idle FreeBSD Virtual PC guest OS will use roughly 40% of the CPU of a single processor computer. After this change, the usage will be closer to 3%.
Create a New Kernel Configuration File
All of the SCSI, FireWire, and USB device drivers can be removed from a custom kernel configuration file. Virtual PC provides a virtual network adapter used by the de(4) driver, so all network devices except for de(4) and miibus(4) 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 Microsoft® Windows® host. This can be accomplished by adding
ifconfig_de0="DHCP"to/etc/rc.conf. More advanced networking setups are described in Chapter 30, Advanced Networking.
VMware Fusion for Mac® is a commercial software product available for Intel® based Apple® Mac® computers running Mac OS® 10.4.9 or higher. FreeBSD is a fully supported guest operating system. Once VMware Fusion has been installed on Mac OS® X, the user can configure a virtual machine and then install the desired guest operating system.
The first step is to start VMware Fusion which will load the Virtual Machine Library. Click to create the virtual machine:
This will load the New Virtual Machine Assistant. Click to proceed:
Select as the and either or , as the when prompted:
Choose the name of the virtual machine and the directory where it should be saved:
Choose the size of the Virtual Hard Disk for the virtual machine:
Choose the method to install the virtual machine, either from an ISO image or from a CD/DVD:
Click and the virtual machine will boot:
Install FreeBSD as usual:
Once the install is complete, the settings of the virtual machine can be modified, such as memory usage:
Note:
The System Hardware settings of the virtual machine cannot be modified while the virtual machine is running.
The number of CPUs the virtual machine will have access to:
The status of the CDROM device. Normally the CD/DVD/ISO is disconnected from the virtual machine when it is no longer needed.
The last thing to change is how the virtual machine will connect to the network. To allow connections to the virtual machine from other machines besides the host, choose . Otherwise, is preferred so that the virtual machine can have access to the Internet, but the network cannot access the virtual machine.
After modifying the settings, boot the newly installed FreeBSD virtual machine.
After FreeBSD has been successfully installed on Mac OS® X with VMware Fusion, there are a number of configuration steps that can be taken to optimize the system for virtualized operation.
