Hi Jianjie, basically GVT-g is based on mediated passthrough technology for graphics sharing between VMs, that could provide full GPU feature as vGPU in each VM, and also secure the isolation among

Hi ACRN community, As I got reply last time from the community, that by using the gvt-g, we CAN NOT assign the e.g. 60 % GPU to uos. Now I have another question is about the theory of GVT-G, If

As you suggest, I add each UOS launch script with an UUID value, and launch the file according to the order of uuid, defined in the vm_uuid.h file. And, Yes, only one UUID is sufficient. Thank you.

Thanks for the confirmation Jianjie Lin! You shouldn’t have to add more UUIDs to that file though, using different ones in each launch script (by adding the “-U” option) should be

Hi Geoffory, Thank you very much. The problem is fixed. It really depends on the UUID in my case. I need to add different UUID from the vm_uuid.h .. Thanks again. Cheers, Jianjie Lin Von:

Thank you, I will try it tomorrow, and give you the reply if something happens. Thanks Mit freundlichen Grüßen Jianjie Lin

That header file contains a fixed (and static) list of UUIDs that can be used to launch VMs. I’m thinking that perhaps what is happening is the acrn-dm uses the same UUID by default for the second

Use different UUIDs in different launch scripts, pick any that is labeled asPOST_STANDARD_VM_UUIDX in the

Sorry, you mean the uuid can only assigned to the one which is saved in the vm_uuid.h? Am I missunderstanding? Mit freundlichen Grüßen Jianjie Lin

Can I use the UUID from each VM, or just two different random UUID Mit freundlichen Grüßen Jianjie Lin

Thanks for trying these out and confirming the results. Do you have any more info from the ACRN hypervisor over the serial port? As per my other email, I’m suspecting something wrong with the

I’m suspicious of something wrong with the UUIDs. Can you try to add the UUID you want to use for the second VM to the launch script, using the “-U” option E.g.: -U

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. Von:

Hi Geoffory, 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? èThe output is

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

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

Thanks Terry, I will look about it Zou, Terry <terry.zou@...>, 2 Eyl 2021 Per, 11:48 tarihinde şunu yazdı:

Wo, you mean ivshmem shared memory privilege for each VM, actually you already referred the doc : ) https://projectacrn.github.io/latest/developer-guides/hld/ivshmem-hld.html Specific to ivshmem,

thank you for your reply, yes I would like to arrange that one vm can read/write to the shared memory (ivshmem) and one of them can only read from there. Zou, Terry <terry.zou@...>, 2 Eyl 2021 Per,

Hi Musa, welcome to ACRN community : ) Specific to you question, do you mean R/W privilege for one storage/partition? One VM can R/W the storage and other VM can only read right. Or other resource
