Re: [WHL] launch two UOSs in the same time

Is that happening no matter which order you try to load them ? .--> yes, no matter in the gpu version or console version. The first one is always correct, but the second one fails always.

Hi Jianjie Lin,
Do you have more logs to share when the second VM fails to start (acrn-dm console & serial port output)? Is that happening no matter which order you try to load them?
A couple of remarks/questions: * Your industry.xml file only ever assigns pCPU 0 and 1 to all User VMs, but your console_launch_uos3_4.sh tries to use pCPUs 2 and 3 * Is gpu_launch_uos4.sh supposed to launch a Windows User VM? I see the ‘--windows’ parameter in it but it seems to want to use GVTg and picks up an image from a folder called “ubuntu_images”. The “--windows” parameter makes acrn-dm use the Oracle Virtio block device.
Thanks, Geoffroy

Hi ACRN Community,
We faced the problem of launching two UOSs at the same time. We deployed the whiskey lake board: whl-IPC-i7.xml, and we customize the scenario file with 4 Post-STD VM.
We can successfully launch one VM, but we can not create the second VM in the acrn kernel.
I attached the two launch file gpu_launch_uos3.sh console_launch_uos3_4.sh
Besides, I attach my board file and scenario file if it can help to find out the issue.
I add the following the command line in the file in the /etc/grub.d/40.cutsom for Gvt-g “i915.nuclear_pageflip=1 i915.avail_planes_per_pipe=0x010101 i915.domain_plane_owners=0x011100001111 i915.enable_gvt=1 i915.enable_guc=0 i915.enable_conformance_check=0”
For each launch file, we can launch the VM without any problem. But If I launch them at the same time, only the first one is successful, the another one is failed to created.
I go through the issue from GitHub. However, no direct solution is founded based on those comments. Do you have any idea how I can forward further?
Thank you very much firstly for your support.
Mit freundlichen Grüßen / Kind regards Jianjie Lin
