Apple Rosetta emulation for QEMU backend #6465

Open freebrowser1 opened 2 months ago

freebrowser1 commented 2 months ago

Describe the issue
Not an issue, but a question. After trying to convert an existing VM (Ubuntu x86-64 emulated on M1) I could not find the option 'Rosetta emulation' in the settings of the VM.

Configuration

Upload VM
config.plist.zip

Rosetta x86_64 emulation only works for ARM64 Virtual Machines using Apple Virtualization. You can't use Rosetta with x86_64 VMs.

Yes you can, if you use Qemu you may launch qemu-aarch-x86_64 in rosetta mode first changing environment in terminal env /usr/bin/arch -x86_64 /opt/local/bin/zsh --login so same behaviour should be available on UTM.

No, that is not how it works. Rosetta is meant to run x86-64 apps on ARM architecture and Apple now supports even Linux VMs on an ARM powered Mac. This documentation : https://docs.getutm.app/advanced/rosetta/ tells about this, but what I don't know and want to know is how to convert an existing VM to Rosetta.

In macOS 15, hypervisor.framework should support this but we'll have to add it to QEMU

What does that mean ? That UTM should be updated to a new, yet to release, version when I update my Mac to Sequoia ?

osy commented 3 weeks ago

Yeah it'll need to be added to QEMU first and then UTM. So probably in the next release.
