Re: Running on AMD systems
|
Hi Lonnie,
I would go first to the acrn-dev mailing list [1] if you have more detailed questions on how to port to AMD, the core developers are watching that one and much less this acrn-users mailing list. I do not know if they have specific knowledge on AMD-V but they would at least be able to guide through the ACRN architecture and content of the source code folders.
The numbers of VMs that can be run by ACRN is something that is defined in the ACRN configuration. It’s a pre-build configuration, not a runtime configuration, which means that any ACRN binary has a limit that’s potentially different. And to change that, you need to modify the configuration and rebuild ACRN. How many VMs would you like to concurrently run?
If you use one of our pre-defined configuration, the “industry” scenario is the one that can run the most VMs, 8 in total (but keep in mind that the Service VM is also a VM, so that’s 7 User VMs).

Hope this helps!

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, Lonnie
