That is, you build and test on macOS with ARM code, commit your changes to whatever release repository you maintain now, the CI system picks that up, tries to build it, runs the tests, and notifies you if anything fails.

If вЂњreally really worksвЂќ is defined in terms of automated testing - and if not, why not? - then it sounds like you want a CI system, though probably not a CI/CD system, if I read your intent properly. Even if you port over the whole userland you depend on, youвЂ™ve still got the macOS kernel under your app, which may differ in significant areas that matter.

Cross-compilation to x86 code under macOS, which allows Rosetta II to take effect, but now you arenвЂ™t running under CentOS proper any more.

#Running linux on a mac software

This should be able to run x86_64 CentOS on an M1, but itвЂ™ll be like the bad old days of software virtualization, back around 2000, where every instruction inside the VM had to be translated into native instructions.Дў. If youвЂ™re willing to drop one of those three parties out of the equation, you have alternatives:ДЎ. ThatвЂ™s not an impossible dance to pull off, but youвЂ™ll need three parties coordinating the dance steps if you want a high-fidelity CentOS-on-bare-metal emulation: Intel, Apple, and your VM technology provider of choice. Intel VT-x) under an Apple M1 ARM64 variant. ItвЂ™s a double translation, you see: real x86 code run on a virtual x86 CPU under your CPUвЂ™s virtualization extensions (e.g. ThatвЂ™s rather difficult when the x86 code in question is on the other side of a virtualized CPU.

#Running linux on a mac update

If you are needing to update your hardware, you need to keep Linux running native on the system, and that system needs to be x86_64, you will either need to get an earlier generation Mac or a current system from Dell, HP, ASUS, etc.

It would be extremely slow, inefficient and probably could not emulate all the hardware needed. First you would have to run a virtual machine on the M1 and that virtual machine would have to emulate the x86_64. The only way to run x86_64 on an M1 is via вЂdoubleвЂ™ emulation.

#Running linux on a mac 64 Bit

x86_64 (or amd64 ) is the native processor name for the Intel/AMD 64 bit architecture. IA64 is the Itanium server which Intel stopped making a while ago and Red Hat quit supporting in 2017.Д¤. Currently the work to get Linux to run on the M1 works great in emulation and somewhat with a lot of work in native mode.ДЈ. The Apple M1 uses a variant of the aarch64 (ARM 64 bit) CPU, and the hardware architecture is different from aarch64 server class hardware in multiple ways.Дў. So, the answer I would give: NO, one can not have guest system of different architecture as it is with decent speed.ДЎ. And later VMware went same way, and became really fast virtualization solution too.Д«ottom line: guest and host systems should have the same architecture for guest system to be able to talk directly to CPU for decently fast virtualization. One can not know that about proprietary software, but give better guess than mine, please. Then parallels desktop emerged and was (without mentioning it) using what Cygwin did. That (emulating generic CPU) was what VMware was doing originally. Otherwise, one has to emulate different architecture CPU, which will make virtualization an order of magnitude slower. This all implies the system of the same architecture on guest system as is of the host system. The first I know of is Cygnus solutions who did it in their cygwin (company was bought by RedHat, and cygwin still exists and still is open source project).

Virtualization solution became fast the moment вЂњon the flyвЂќ conversion of guest system calls to host system calls was invented.

Parallels/VirtualBox intend to support IA64 based OSвЂ™s and it *needs* to be an exact (VM) copy of production so I can trial environments and builds prior to roll out.Д¬alling around, I actually got ahold of a sales staff at Parallels who assured me (in broken India-accent English) that вЂњof course all OS will supported when the trial completeвЂќ but given that I wasnвЂ™t sure that he really understood my question I remain uncertain.ДЄnybody here have any more information than I do? > IвЂ™ve been unable to officially confirm that VMWare/ My Dell Precision M3800 running Fedora works great but is really starting to show its age, and IвЂ™m thinking about getting a new Mac M1-based laptop as it would really be useful for Video production.Д«ut I really need to have a IA64 CentOS 7/8 VMs running locally for development as IвЂ™m often on the road and flaky Internet makes it a necessity to keep productivity up.
