Can Vanilla support AMD-V (SVM)?

[tylinux]

I installed macOS 10.14.4 on my Ryzen 1700 device via Valilla. Everything is perfect except Virtual Machine.VirtualBox is usable but bad performance。 I confirm that SVM support is turned on in the BIOS setup，but the output of sysctl machdep.cpu.features command don't contain 'svm'. Is there any way to support it ?

@tylinux Hi. Have look at this https://github.com/moby/hyperkit/issues/230

I don't think it's vanilla's fault nor virtual box. Because apple never have an AMD based machine, so software vendors assume that they don't need to compatible with AMD. Also software vendors can't fully test their softwares on AMD hackintosh since the machine specs varies.

I'm using VMs on AMD hackintosh, the vmware fusion works. However only ver 10 works (10.1.6 (12989998)), the latest 11 doesn't.

Hi, I run Virtualbox on my AMD Ryzen and Virtual PC show good speed and detect real CPU.

CPU Perfomance is the same when I ran Virtualbox with Windows on Ubuntu in this PC (I use it for MetaTester)

@zalivar71 Hi, Could you please provide which version of VirtualBox you are using. I'm also interested in VirtualBox, since the vmware only provide paid license.

[zalivar71]

@tedli Version 6.0.10 r132072 (Qt5.6.3) And my config of VirtualPC

PS I sure you checked, but I should to ask:), did you checked Virtualisation Checkbox in BIOS in CPU Options? Some Hackintosh manuals recommended disable this function.

@zalivar71 Thanks for reply. I did check the Virtualization (SVM) in BIOS (SVM enabled). Indeed many manuals told to turn it off. I don't know why. But for my machine, turning SVM on didn't trick me, everything works fine.

I know it's not vanilla's fault nor virtual box. I just want to know if there is a way to patch kernel or something else to let application like VirtualBox or sysctl machdep.cpu.features to know this machine support svm, maybe my vm's performance will be better.

I use libcupuid to detect my cpu info, report is

svm is enabled..

I have the same problem, with vmware pro 11 and parallels the app would either crashes or hang my machine. Docker doesn't work either.

ended up with vmware pro 10.

[JoelNichols]

VirtualBox works just fine for me with these patches. Haven't tried VMWare or Parallels but don't see much point as it seems fairly established to me that they won't work.

Thing is, should this even be an issue on this repository? This isn't an issue with the patches themselves but rather the fact that Mac app developers aren't going to be rushing to add AMD virtualisation support.

@zalivar71 Can you share your config and kexts from Clover?

@zalivar71 Can you share your config and kexts from Clover?

@LiuJiangshan Hi, Sure. Don't forget to change S/N in SMbios https://yadi.sk/d/XD_d2iUDqHAiyg

Is there any update on this matter as of 2023.

I have a ryzen cpu which supports svm , enabled in bios , however ‘svm’ not appearing in list of cpu features and virtual box won’t launch any vms successfully .
