  1. ACRN project update:
a . Video Conference Tool for TCM:
‘Video Quality’ and accessibility issue of Zoom, especially in China. We are seeking other tool for ACRN TCM: Teams, Webex, Tencent Meeting are options, welcome all your preference and ideas, thanks.
b.  De-privilege mode to Grub boot change: 
De-privileged boot mode was used with Clear Linux SOS, it de-privilege UEFI execution environment from native to Service VM non-root mode, but must ensure any hardware resource touched by UEFI FW before de-privilege must keep the same configuration after boot to service VM. It brings lots of scalability issues when porting ACRN to new platforms. 
So we plan to remove de-privilege mode, and go direct boot mode only, you can find grub boot doc here: https://projectacrn.github.io/latest/tutorials/using_grub.html.  Move document updates are planned in the coming V2.2 release.
Feel free to discuss any concerns of this change in mailing list, thanks.
