runtime VS UTM

Let me give you an example. [Here's one of the best questions I've ever asked on the internet.]https://github.com/kata-containers/runtime/issues/2795) I've seen many better questions asked, but this is the best I've been able to manage. I provided a decent description of the problem, a test-case that allowed other people to reproduce it as well (not relevant in your case), what I tried that didn't work, and the exact log messages and system information that indicated the problem. I then followed up with the people who were helping me and the problem was resolved.

in parts of prod we use a combination of cgroups (mentioned in the thread already), taskset https://man7.org/linux/man-pages/man1/taskset.1.html, and in other cases (HPC workloads on large clusters) Kata Containers to isolate and optimize application resources: https://katacontainers.io/

It might use a hypervisor though, as the pendulum swings back

If you have TrollStore then install the HV version of UTM to try for yourself: https://github.com/utmapp/UTM/releases/latest/download/UTM.HV.ipa

Researching a little showed that this is basically what can be expected running x86 emulation and the systems will just be wonky and slow, although it was running flawlessly, just slow.

There seem to be ways to use Rosetta2 inside a VM [0] to then translate binaries but I found no official support or documentation (using UTM+QEMU that was), this would be such a cool feature, at least there are discussions about it [1,2]

UTM is open source too though: https://github.com/utmapp/UTM#license

UTM makes it easy to set up and manage macOS and Windows virtual machines. This can be especially useful for developers such as Tauri contributors who need to test their applications across multiple platforms, or for those looking to experiment with different operating systems without affecting their primary system.

If you don't need high performance and want to use the OS only occasionally, check UTM.app, at https://mac.getutm.app/ (or https://github.com/utmapp/UTM ). Free, open source.
