ACRN hypervisor build fails with internal error

jan.hoffmann2@... #1218 Hi Junjie! Thanks for the explanation. We are investigating if can use ACRN as hypervisor for an edge cloud in the manufacturing environment. We want to deploy real time and non real time VMs for control and regulation of manufacturing the processes. I was able to build the hypervisor with you fix. So thanks again for that. I will continue with my test and let you know, whether I find any other issues. Regards, Jan

Junjie Mao #1217 Hi, Welcome to ACRN! What this calltrace complains about is that the platform has multiple sockets and thus L3 caches which is a case beyond ACRN's common uses today. However, multiple sockets may not hurt if CAT (Cache Allocation Technology) is not to be enabled which is the case according to your scenario definition. Here's a one-liner patch to skip the L3 cache related logic at the configuration phase (just cherry-pick the first commit in this branch): https://github.com/junjiemao1/acrn-hypervisor/commits/release_3.0 While that allows you to build the hypervisor, there could be other issues when deploying ACRN on a server like yours. May we know your intended use case for running ACRN on a server? -- Best Regards Junjie Mao "Liu, Fuzhong" <fuzhong.liu@...> writes: toggle quoted message Show quoted text Hi, recently I started with the getting started guide for version 3.0.

Liu, Fuzhong #1214 Hi Thanks for try ACRN v3.0! Ubuntu 20.04 is verified for v3.0. Do you build ACRN with ubuntu 20.04? BR.
