VirtualBox 5 with Extensions

MAAS_VirtualBoxThis project offers a set of basic extensions for MAAS to integrate VirtualBox VMs. It has been tested with VirtualBox 4.3.20r96996 for OS X (Mavericks 10.9.5), hence different versions of VirtualBox and/or VirtualBox running on other host machines may have some issues.These extensions work well for testing, demoing and development, but they are not recommended for production use.FeaturesThe VirtualBox extensions for MAAS offer these features:VirtualBox VMs can be autodiscovered, they can be started, commissioned and acquired.Multiple VirtualBox host machines are allowed, provided they are accessible from the MAAS server and the MAAS server can offer PXE Boot, DHCP and DNS services.Current LimitationsAt the moment, the VirtualBox extensions for MAAS have these limitations:VirtualBox VMs cannot be checked, i.e. administrators using MAAS cannot check from MAAS if the node is ON or OFF by using the "Check power state" button in the "Edit Node" page.VirtualBox VMs cannot be stopped from MAAS.The Wake-on-LAN option is no longer present in MAASThe description of the physical zones in MAAS is no longer freely usable (it is reserved for the extensions).A power request is sent to all the available VirtualBox host machines, i.e. at the moment the scripts do not check which VirtualBox machine hosts the VM.The error status of many commands in the powering process is not checked.The testing is limited to Ubuntu VMs on VirtualBox host machines in OS X Mavericks 10.9.5.Basic ConceptsThe VirtualBox extensions for MAAS are used to control VirtualBox VMs from the MAAS server. At the moment, only the "Start Node" (or Power ON) action has been implemented, but there are already scripts that can be used to integrate "Stop Node" (or Power DOWN) and "Check power state" (or Power CHECK).The extensions rely on these basic concepts:The MAAS server and the VirtualBox host machines are connected to the same network: this is also essential to allow PXE boot of the VMs, the use of OS images hosted by the MAAS server and the use of DHCP and DNS services, also offered by the MASS Server.The MAAS server must send ssh commands to the VirtualBox host machines.The VirtualBox extensions replace the Wake-on-LAN option in MAAS: this means that the parameters used to identify a VirtualBox VM must be added to a node by using the "Power Type" options for Wake-on-LAN. It also means that the standard Wake-on-LAN power option is no longer available on the MAAS server.The VirtualBox host machines are identified by MAAS physical zones.A MAAS physical zone can refer only to one VirtualBox host machine.Many MAAS physical zones can refer to the same VirtualBox host machine, although this is not advisable: the best approach is to identify one physical zone in MAAS for one VirtualBox host machine.The maas user on

Or closing the Terminal window)When VirtualBox and all related components and kernel extensions has been removed successfully, you can close the Terminal window or quit out of Terminal app as needed. Manually Uninstalling VirtualBox from a Mac: Locations of All Related Files, Directories, etcIf you prefer to be hands-on, you can also manually uninstall VirtualBox by parsing through “VirtualBox_Uninstall.tool ” to find the exact file paths or all VirtualBox directories, components, the application, bins, launch daemons, kernel extensions, and more. You will want to do this manually using the version of the installer that you installed VirtualBox with so that you don’t miss anything.As of the time of this writing, the current VirtualBox app and associated file path list is as follows:~/Library/LaunchAgents/org.virtualbox.vboxwebsrv.plist /usr/local/bin/VirtualBox /usr/local/bin/VBoxManage /usr/local/bin/VBoxVRDP /usr/local/bin/VBoxHeadless /usr/local/bin/vboxwebsrv /usr/local/bin/VBoxBugReport /usr/local/bin/VBoxBalloonCtrl /usr/local/bin/VBoxAutostart /usr/local/bin/VBoxDTrace /usr/local/bin/vbox-img /Library/LaunchDaemons/org.virtualbox.startup.plist /Library/Python/2.7/site-packages/vboxapi/VirtualBox_constants.py /Library/Python/2.7/site-packages/vboxapi/VirtualBox_constants.pyc /Library/Python/2.7/site-packages/vboxapi/__init__.py /Library/Python/2.7/site-packages/vboxapi/__init__.pyc /Library/Python/2.7/site-packages/vboxapi-1.0-py2.7.egg-info /Library/Application Support/VirtualBox/LaunchDaemons/ /Library/Application Support/VirtualBox/VBoxDrv.kext/ /Library/Application Support/VirtualBox/VBoxUSB.kext/ /Library/Application Support/VirtualBox/VBoxNetFlt.kext/ /Library/Application Support/VirtualBox/VBoxNetAdp.kext/ /Applications/VirtualBox.app/ /Library/Python/2.7/site-packages/vboxapi/ org.virtualbox.kext.VBoxUSB org.virtualbox.kext.VBoxNetFlt org.virtualbox.kext.VBoxNetAdp org.virtualbox.kext.VBoxDrv org.virtualbox.pkg.vboxkexts org.virtualbox.pkg.virtualbox org.virtualbox.pkg.virtualboxcliTargeting those files and directories one by one for removal is probably easiest through the Terminal, but you could certainly do through the Finder if desired.Obviously if you uninstall and remove VirtualBox, it won’t be on the Mac anymore, but you can reinstall it again at any point in the future if needed.

Workarounds and limitations, there are other alternatives to consider:Browser extensions: Instead of running Safari on a Windows machine, you can install browser extensions like the Safari Browser Extension (formerly Safari for Windows) on Google Chrome or Microsoft Edge.Web development tools: If you’re a developer, you may already have access to virtual machine software or cloud services that allow you to simulate a Mac environment.How to Run Safari on WindowsIf you’ve decided to run Safari on Windows, here’s a step-by-step guide:Method 1: Using Virtual Machine SoftwareInstall VirtualBox: Download and install VirtualBox, a popular virtual machine software.Create a new virtual machine: Set up a new virtual machine by choosing the macOS High Sierra (or later) template.Configure the virtual machine: Install the Safari browser on your virtual machine and configure settings as needed.Method 2: Dual-booting with macOSPartition your hard drive: Create a secondary partition on your Windows machine and install macOS alongside.Install Safari on macOS: Install the Safari browser on your secondary partition.Boot into macOS: Select the macOS partition and start up your machine in dual-boot mode.Browser Compatibility and PerformanceRunning Safari on Windows may pose some compatibility and performance issues, including:Render-blocking scripts: Some web pages may render scripts or content incorrectly due to Safari’s unique rendering engine.Graphics performance: Safari’s graphics acceleration may not work optimally on Windows, leading to slower performance.Plug-in compatibility: Plug-ins and extensions may not be compatible with Safari on Windows, leading to inconsistencies.ConclusionRunning Safari on Windows is possible, but it requires some workarounds and technical know-how. If you’re a developer, tester, or simply prefer the Safari experience, understanding the limitations and requirements will help you make an informed decision.Key Takeaways:Windows 64-bit requirement: Safari only supports 64-bit versions of Windows.Virtual machine or dual-booting required: To run Safari on Windows, you’ll need virtualization software or dual-booting with macOS.Browser extensions available: Browser extensions
