Hello Yinsi/Yuchan,
Happy Lunar New Year!!!
David and Luca (on CC) are hitting a few bumps trying to get the QEMU instances running in a docker container on the OpenEuler OS install you setup for us. The QEMU instances are failing to boot from NFS.
Thinking it might be a permission problem, we confirmed that the containers are run as root and SELinux is disabled yet the problem persists. We did replicate the setup on a Debian Aarch64 system and it worked so we suspect there's something in OpenEuler OS we haven't configured correctly.
This is QEMU's instance booting log you: https://lkft-staging.validation.linaro.org/scheduler/job/100307
Can you please work with David and Luca to try and figure this out.
Cheers! anmar
