![]() Another negative is that there are very little applications compiled for running on an ARM-based Windows version. Microsoft decided that this is only available for sale for system builders. The downside for this approach is that there is no official way, currently, to get a license for an ARM-based version of Windows. Leaving only virtualization as a real option. As it’s using QEMU under the hood, it is capable of emulating different processor architectures (like x86-64) but it can do virtualization for the same as the host’s architecture as well.Īfter a quick test, on which I plan to create a more detailed article in the future, using emulation seems to cause a lot of overhead and turns out to be too slow to be usable currently. UTM offers QEMU-based virtaluzation and emulation with a handy GUI for both IOS and macOS. Virtualization is fast(er) but requires software written for the hardware platform it is running on.īoth of these methods can be accomplished with UTM ( ). ![]() Emulation offers maximum compatibility as it doesn’t require software written for ARM specifically but it’s pretty slow. Both methods have their advantages and disadvantages. ![]() The second involves emulation, where we will translate instructions between the running operating system (Windows in this case) and the hardware. The first involves virtualization, as we can’t (yet) run Windows natively on an M1-based machine. So instead I referenced the UEFI BIOS as a command line parameter.As mentioned above, there are two options to get Windows running on an Apple M1-based device. I've tried it in the OS XML Block, but it cannot seem to find it: So far, all I've figured out is that I need to reference this EFI firmware: However, I'm working off of the same tutorial that you are, and there are some other changes that need to be made too. This seems to stop this error from happening. If you try to pass a longer string in the XML as you have done, then QEMU will see it as a single long commandline argument with embedded spaces, which it will then probably treat as a very odd disk image filename or complain about as invalid.Īnd re-compile. (You can see that the q35 options you've commented out are all specified in this way, unlike the ones you've added for the virt machine: look at the difference between the -netdev handling there and what you have, for example.) Specifically, each "qemu:arg" tag in the XML must specify one single command line argument word, so if you want to say "-accel hvf" you must write Īnd so on for all the other options and arguments you want to specify. I think that this is happening because your XML syntax is incorrect and so QEMU is not seeing your attempt to tell it to use hvf. (Latest upstream QEMU has a workaround for this in commit c118881ee607dcac, but you don't need that since you're only running into it because hvf is not actually being used.) It then tries to fall back to TCG (pure emulation), which also fails, because of a macos bug involving mprotect(), hence "Could not allocate dynamic translator buffer". QEMU appears to be trying use the KVM accelerator, which obviously does not work on a macos host, so QEMU reports "invalid accelerator kvm". Try to run this on Apple Silicon with qemu-system-aarch64, but got an error:Įrror: internal error: Failed to start QEMU binary /usr/local/bin/qemu-system-aarch64 for probing: qemu-system-aarch64: invalid accelerator kvmĬould not allocate dynamic translator buffer
