VBoxManage setextradata VM “VBoxInternal/CPUM/MSRs/MsrBiosSign/First” 0x0000008B

So to override it, run the following code: What is however more important in our case is that any MSR override added this way will also ignore all writes into that MSR – and this is exactly what we need, as VirtualBox has this register marked as read-only. And if you want a specific value to be read from MSR, you can add it as Value. If you want to override the register range, you can put the last register in the range into Last value key, which would cover the First-Last range. First value must be the first MSR register value to override, in our case 0x8B. Here name is a user-defined name (it is used for logging and retrieval of subsequent values). VBoxManage setextradata VM “VBoxInternal/CPUM/MSRs/ name/Value value VBoxManage setextradata VM “VBoxInternal/CPUM/MSRs/ name/Last value VBoxManage setextradata VM “VBoxInternal/CPUM/MSRs/ name/First value VirtualBox contains (internal) settings to override MSRs, see function src/VBox/VMM/VMMR3/CPUMR3CpuId.cpp – the format is the following: If we could ignore this write, we should be able to proceed further!įortunately this is possible. Which means the CPU attempted to write the MSR register 0x8B the instruction wrmsr 0x8b, 0 – and the reason for the crash. Fortunately we can spot in the log we see the following reason for crash: This is a rather tough error to debug as this means the CPU encountered an exception while already reacting on the exception. This will bring us further in the OS X load process – now it crashes with Guru Meditation 1155 (VINF_EM_TRIPLE_FAULT). Note that the second instruction from the script above (setting –cpuidset 00000001) should NOT be executed on AMD CPU. The OS X checks the CPU brand by using CPUID instruction, so we can modify its output in VirtualBox to masquerade our CPU as Intel: More changes are needed.įirst, we need to tell VirtualBox to present its CPU as Intel. However this will not be enough on AMD CPU, where the OS X kernel will halt (Mavericks) or crash (Yosemite) on boot.

While VirtualBox does not officially support OS X guests on non-Mac hardware, it is still trivial to do so, as described in the following post. Installing it on a machine with Intel CPU is not a problem. You can follow our blog for new images we release for VirtualBox.Before you proceed: there is NO working solution yet, and I was not able to run unmodified Mac OS X guest on AMD CPU under VirtualBox.

It is a free and powerful x86 and AMD64/Intel64 virtualization product available for most of the operating systems such as Linux, Microsoft Windows, Mac OS X, Solaris and ported version for FreeBSD.
#Virtualbox mac os x guest amd install#
VirtualBox is the most easiest way to run secondary OS on your primary operating system, If your hardware doesn’t allow you to install any other operating system then VirtualBox comes in hand. We do not install ‘Guest Additions’ in the OS or add any kind of stuff, read our privacy policy.

Here you can follow the guide how to attach/configure VDI image with VirtualBox. You can check FAQs for Credentials( Username & Password) for VDI images. At the moment we have plans to offer you 30+ Linux/Unix distributions, we may add more to our list in near future, you can also send us suggestions if we are missing any popular distribution from our list.
#Virtualbox mac os x guest amd for free#
We offer images for both architectures 32bit and 64bit, you can download for free for both architectures. From here you can download and attach the VDI image to your VirtualBox and use it. We offer open-source (Linux/Unix) virtual machines (VDIs) for VirtualBox, we install and make them ready-to-use VirtualBox images for you.
