Hi Fengwei,
I have tried two ways to boot preempt uos, but no success. There were error logs in the previousemail.

So you saw "pci passthru fail" when you use your launch_hard_rt_vm1.sh?
Could you please share the whole launch_hard_rt_vm1.sh script?

Also the version of acrn hypervisor, acrn-dm and SOS kernel version
could help here. Thanks.

Hi Siming,
I suppose you need passthru the SATA controller to your second VM.

Hi

Could you please double check if it can native boot from sda?

1. set boot order to Built-in shell;
2. type fs0: ENTER
3. cd EFI/BOOT ENTER
4. run BOOTX64.EFI

BR.

thanks for the direction, the dd commond works fine in the
native boot, but the launch rt vm still failed (in acrn boot).

I tried two way to launch the vm, the difference is "-s 2 " of
the acrn-dm.

thanks for the responds.I did the dd comond in the acrn boot.

After I install the service VM with./acrn_quick_setup.sh
,I cannot boot into /Clear-linux-native-5.5.11-922/. The
HDMI is nothing out when I choose this.

/  Clear Linux OS(acrn)/

/  Clear Linux OS(Clear-linux-iot-lts2018-sos-4.19.97-104)/

/  Clear Linux OS(Clear-linux-native-5.5.11-922)/

Did I miss something in the set up of the service vm?

thanks

Hi

The dd issue is for acrn boot or native boot?

Please  boot into native and try it again.

Thanks!

Hi,

  My board is NUC7i5BNB, with two disks: an NVMe disk
for the Clear Linux-based Service VM and a SATA disk
for the RTVM.Accoring to
https://projectacrn.github.io/1.6/getting-started/rt_industry.html#install-and-launch-the-preempt-rt-vm,
when I write preempt img to sata, there is always have
gpt errors. I have chaged another sata disk, but it's
the same error.
