Re: ACRN's OTA: it leverage SOS's capability to do OTA

Choong, Yin Thong


Just FYi.


Clear linux have swupd behavior which can get latest acrn.efi from upstream. Maybe need some extra post process to complete the arcn.efi update by copying the latest into /boot.


Thanks and Regards

Sorry for broadcasting, but FYI..


I have ported ACRN hypervisor/SOS/UOS to yocto, please see my project if you have interest:


With this meta-acrn, there is also a TUF based OTA framework and a meta-updater yocto layer:, that we can implement a OTA solution on top of them, which I am working on. Please join me if you also have interest.

Hi all,


One question from ACRN Technical Community Meeting (TCM) this week is whether ACRN support updated feature like OTA.

Here’s the feedback from ACRN’s engineering team:  right now ACRN hypervisor is stitched (build-in) with SOS image, for example Clear Linux as Service OS, so the ACRN’s update could be done by SOS if SOS has such capability.


Thanks for the questions.



Best regards.
