Im using VZVirtualMahcine with Linux guest system. Every once in a while, for no apparent reason, VM just freezes completely (screen just freezes at current state), and CPU usage of the process on host is using 100%. I need to force quit the app then. This happens even if guest os is just running doing nothing. Anyone else experienced this kind of behavior? It was like that on Ventura, and now also on Sonoma. Xcode 14 and 15.

My device is MacBook Pro 13-inch, M1, 2020 Use source code provided by article https://developer.apple.com/documentation/virtualization/running_gui_linux_in_a_virtual_machine_on_a_mac When installing Debian, Fedora or Ubuntu, installation process can stuck at any point and cause the installation failed. Even if it is lucky enough to pass the installation phase, stuck could still happen at any time when the virtual machine is started. It seems that there is some low level error that cause the Linux kernel panic, while during this process error seems to be accumulated--it starts with some user level application in Linux starts to behave weirdly, such as sudo does not authenticate a valid user, apt can not run properly, then Linux kernel panic. Sometimes it behaves like the VM get stuck where it is not sure what happened inside it. I can't provide more detail as it happens randomly and the phenomenon differs each time. While generally it appears to be an accumulated error and eventually the VM get stuck.

I m trying to identify if my launched process is running on a local mac machine(desktop/laptop) or a virtual macOS X instance like AWS EC2, Azure, MacStadium etc. I am using the below check for this: 1 . If running on native Apple hardware, the returned value contains the model name of the hardware: $ sysctl -n hw.model Macmini8,1 On virtualized hardware, the value may contain the hypervisor name: $ sysctl -n hw.model VMware7,0 If the command output doesn't contain the "Mac" substring, the malware considers that it is running in a virtual machine. 2. Checking USB device vendor names The commands used: ioreg -rd1 -c IOUSBHostDevice | grep "USB Vendor Name" Sample output on native Apple hardware: "USB Vendor Name" = "Apple Inc." "USB Vendor Name" = "Apple Inc." "USB Vendor Name" = "Apple, Inc." On virtualized hardware, the value may contain the hypervisor name: "USB Vendor Name" = "VirtualBox" "USB Vendor Name" = "VirtualBox" A virtual machine can be detected by checking if the command output contains a hypervisor name, for example "VirtualBox", "VMware", etc. 3 . Checking the "IOPlatformExpertDevice" registry class The command used: ioreg -rd1 -c IOPlatformExpertDevice The following fields of the IOPlatformExpertDevice class can be checked in order to detect a virtual machine: I wanted to know can a combination of these be used to identify a process running on a Cloud VM with certainity?

I installed Gentoo in virtual machine using Apple Virtualization framework. In linux then I installed avahi, configured the network in Bridge mode. Now I want to connect from this virtual machine to other computer in local network. I can see other computers on the local network, and connect with them using local IP address. But for some reason these are not detected using .local domain. I run avahi-browse -at|grep PS3 and it detected 4 entries for this computer: IPV4 _ssh._tcp local IPV6 _ssh._tcp local IPV4 _sftp-ssh._tcp local IPV6 _sftp-ssh._tcp local Also avahi-resolve -n PS3.local correctly detects IPv6 address of this machine. So why cannot I connect with the computer using PS3.local name?

I m trying to identify if my launched process is running on a local mac machine(desktop/laptop) or a virtual macOS X instance like AWS EC2, Azure, MacStadium etc. I have followed this link which searched for its limited providers in the output, but I m not bound to any limited providers and looking for a general solution which is applicable to all the providers. Is there some hardware/network/virtualization-related information that can be used to identify if the process is launched on a virtual MacOS instance? OR is there some system Information that I can use to be sure that my process is running on a local machine?

I am following example on Apple docs: GUILinuxVirtualMachineSampleApp I am able to create GUI VM first time but from second time onwards it throws error Guest did stop virtual machine. 2023-10-01 20:45:08.991551+0530 GUILinuxVirtualMachineSampleApp[6417:1426889] [client] No error handler for XPC error: Connection invalid Thought some permission error, app cannot access the VM bundle, tried giving all perms, but didn't help, also the error is not specific as to why did guest stop the VM. Please let me know what might be the cause and how to move forward. Deleting VM bundle and restarting works but that's not the solution I am looking forward too.

Hi, I'm trying to implement macOS virtualization on the M1 Sonoma mac mini. Configuration: OS- Mac m1 sonoma Build version- 23A5286i ProductVersion- 14.0 Virtulization image- 13.5.2 bulild version IPSW file - /UniversalMac_13.5.2_22G91_Restore.ipsw I'm following the documentation - https://developer.apple.com/documentation/virtualization/running_macos_in_a_virtual_machine_on_apple_silicon?language=objc Getting following error while reloading the restore image- MacOSVirtualMachineInstaller.swift:32: Fatal error: The restore image failed to load. Unable to connect to installation service Please help.

I have a Mac OS virtual machine (VM) on my Macbook Pro with M1 Pro chip. The VM was set up using Xcode and Apple's sample code in https://developer.apple.com/documentation/virtualization. Both the host and the VM have Mac OS 14. The mouse and trackpad scroll direction is reverse to what I am used to so I need to change the natural scroll setting. However mouse and trackpad settings are missing in my VM. Usually, they are under Keyboard (host has them). The pointing device was set up using the default in the sample code: static func createPointingDeviceConfiguration() -> VZPointingDeviceConfiguration { return VZMacTrackpadConfiguration() } I have been using this setup before without a problem. But now I am not able to change the scroll direction. Does anyone know what is going on? Any suggestion will be appreciated.

Is enabling nested virtualization on roadmap for MBP M2Pro/Max? Will this ever be a software setting on M2 that we could enable by toggling a button?

Hello, When building and running the GUILinuxVirtualMachineSampleApp, I immediately get the error : "Failed to retrieve the machine identifier data." The app runs with a black window and an infinite loop icon without the file picker prompt as expected. Hardware : MacBook Pro M2 OS : macOS 13.2.1 Can't understand what's causing it relatively to the VZGenericMachineIdentifier object. Any insight or suggestion would be more than appreciated. Thanks in advance :). Sincerely, hex0x40

@eskimo Hi! I tried out this new download. I'd installed it on the Ventura host and in the Sonoma VM, but the Sonoma Beta 1 VM does not "see" Beta 2. https://developer.apple.com/download/ How do we update our VM running macOS 14 beta 1 to beta 2?

Trying to get some minimum development working again, I've been waiting to be able to macOS in VMs on M1. Currently both VirtualBuddy, and UTM, can install macOS, I can go to Recovery Boot to disable SIP and enable 3rd party extensions. My M1 runs: ProductVersion: 13.0 BuildVersion: 22A5331f I've tested VM macOS versions of Monterey and Ventura. Here is my old kext (known to be working) loaded on M1 (Ventura) bare-metal 250 0 0xfffffe0006b70000 0x862ac 0x862ac org.openzfsonosx.zfs (2.1.0) BE4DF1D3-FF77-3E58-BC9A-C0B8E175DD97 <21 7 5 4 3 1> The same pkg, using the same steps in the VM, will after clicking Allow, ask to reboot (suspiciously fast), then come up with: System Extension Error: An error occurred with your system extensions during startup and they need to be rebuilt before they can be used. Of course clicking Allow just does the same, reboot, fail, ask to approve again, reboot..fail... Directly on the hardware, the dialog "rebuilding cache" pops up for a few seconds, but with the VMs I do not see it. I'm unfamiliar with the new system, so I'm not sure which log files to look at, but here is the output from kmtuil log, both at Allow and after reboot: https://www.lundman.net/kmutil-log.txt If I was going to make an uneducated guess and pull out some lines by random, maybe: 2022-08-29 20:01:13.169897+0900 0x251 Error 0x0 100 0 kernelmanagerd: Kcgen roundtrip failed with: Boot policy error: Error creating linked manifest: code BOOTPOLICY_ERROR_ACM 2022-08-29 20:01:13.170200+0900 0x251 Error 0x0 100 0 kernelmanagerd: Kcgen roundtrip failed checkpoint saveAuxkc: status:error fatalError:Optional("Boot policy error: Error creating linked manifest: code BOOTPOLICY_ERROR_ACM") 2022-08-29 20:01:13.170201+0900 0x251 Error 0x0 100 0 kernelmanagerd: Kcgen roundtrip failed: missing last checkpoint or errors found 2022-08-29 20:01:13.170242+0900 0x251 Default 0x0 100 0 kernelmanagerd: Deleting Preboot content Any work arounds? Loading kexts on my only M1 is a hard way to develop.

Hi. Sorry if this question has been answered in another post, if it has I can't find it. My device is MacBook Pro 16-inch, M1, 2021. So I tried to create a VM using this guide from Apple I followed the guide and used an image of debian. Everything worked fine until the machine appeared stuck at some point of the installation. I chose my languages then I had some other prompt asking me to install something but I can't remember precisely the step at which I thought it was freezed (I think it was the GNOME install) So because the machine was not responding for several minutes (I might have been too hurried) I quitted the process by simply clicking on the Quit button in the VM window. The problem is that from that point onward, I can't load any VM anymore. The build is successful in Xcode, the machine starts but immediately quits with this response from Xcode logs : Virtual machine successfully started. Guest did stop virtual machine. 2023-02-02 22:22:45.413600+0100 GUILinux[22984:380971] [client] No error handler for XPC error: Connection invalid I just can't understand why, I tried to delete and download the guide again but it doesn't work. I will add that it's my first time using Xcode and I might have missed something obivous.

Neat, looks like macOS Sonoma has native virtualisation now. You have to build a Swift app, which is a bit weird, but it works, and on an M1 chip. One thing though... here's a screenshot of the Displays screen in Settings: Curious why these two resolutions were decided. My host screen is 1920 x 1080, so one resolution is far too high, and the other is just a bit too small. Something in between would be nice! Here’s the guide if anyone wants to have a go: https://developer.apple.com/documentation/virtualization/running_macos_in_a_virtual_machine_on_apple_silicon You’ll need macOS 14 Sonoma and Xcode 15 beta

I've written a native app for macOS on my MacBook Air (with the Apple M2 chip.) Now I need to test it for an Intel-based CPU. When I build my app in Xcode, it is supposed to cover both ARM64 and x86-64 architectures in a single Mach-O binary, but when I send it to my customer he tells me that the app works on the Apple silicon but it crashes on his Intel-based Mac. So I'm looking for ways to test-run my app on an Intel-based platform and see what is wrong there. (But I obviously don't want to buy a separate Mac just for that.) I know that one can use Azure to spin up a Windows, or a Linux VM and open it via a web browser. But it doesn't seem to support macOS. How can I run an Intel-based macOS in a virtual environment? Or, do you have any other suggestions?

Hi there-- Ive been trying to recreate an issue with a camera app im developing on a clean install. I can easily start up a new VM with VirtualBuddy, UTM or Parallels but Im having trouble getting a camera device to passthrough. Parallels seems to be the most promising but whenever I try to connect it, there is an error. Does anyone have advice on the best VM provider to use to passthrough usb devices or native cameras? Thanks!

I'm used to test all the Beta version on Virtual OS ... With the new framework there is no way to sign with iCloud account. so no way to put an account to update the VM with a new beta who is released. The only solution is to setup a new VM. that is a real limitation as update process is important to test too... Any one have a solution?

I want to expose a directory to MacOS VM when it is running. Apple's documentation mentions this (here) : The VZDirectoryShare on the configuration defines the host directories to expose to the guest. To limit or expose new directories to the guest while the VM is running, you can update the directory share with VZVirtioFileSystemDevice. But I tried the following when VM is running: Changing the original configuration of directory (saved the config applied, then changed it) Added new directory share in the original configuration Restarted running VM after (1) and (2) None of them are working. Anyone has any idea how to make this work ? Or this is not currently supported ?

I'm trying to create a vsock socket on the host but it fails with ENODEV. I know I can use a VZVirtioSocketDeviceConfiguration and get one through the Virtualization Framework, but for my use case it would be easier to integrate if I can create the socket myself. This works from inside a VM assuming I've configured a VZVirtioSocketDeviceConfiguration, but not on the host. #include <sys/types.h> #include <sys/socket.h> #include <stdio.h> int main() { int fd = socket(PF_VSOCK, SOCK_STREAM, 0); if (fd < 0 ) { perror("socket"); } return 0; }

Hello, I am running a virtual machine on my Apple Silicon Mac, using the sample Xcode project provided by Apple last year. I have Ventura 13.4 installed on on the host and the VM. I try to enter my Apple ID credentials in "Sign In with Apple ID" in the VM so I may then update this VM to Sonoma. I am sure I am getting my password correct. I cannot log in. Please see the screen shot. Am I supposed to be able to do this? I can log into developer.apple.com within the VM OK. Thank you. FB12263051
