Re: Running on AMD systems

Lonnie Cumberland <lonnie@...>

Hi Geoffroy,

Thanks for getting back to me on this and I will see what I can do, but highly doubt that I have the skillset to make the patches for it to run on AMD. I will give it a try though.

There aren't by chance any developers that I might be able to contract to help get the AMD version running is there?  Like I mentioned, I will give it a try, but do not have much confidence in my possible success.

On another question, I was reading over the documentation and it seems that ACRN is limited to the number of VM's that it can concurrently run. Is that correct?   What I had come across has to do with Pre-Loaded VM limits which seems to suggest that a max of 7 was possible. Perhaps I missed something.

Best Regard as well,

Hi Lonnie,


Happy New Year to you too!! :-)


The short answer is that we have not tested ACRN on AMD processors. I strongly suspect that ACRN will not run on AMD at this stage due to the differences in the HW-assisted virtualization extensions (Intel VT vs. AMD-V). Having said that, please let us know if you get it to work! We’d also be happy to take patches if you create a port for AMD.


Best regards,

Hi All,


First of all, I would like to say Happy New Year to everyone.


Not sure if I have asked this, or if it has already come up, but I was wondering if ACRN will run on AMD processors.  Actually, I am looking for an extremely small footprint monolithic  hypervisor that can run on AMD and Intel processors as I investigate Uni-kernel approaches for JEOS streamlined applications.


Hoping that ACRN can be a good starting point for this effort that I have had in mind for a very long time now.
