some windows guest has experience bsod sometimes when passing through AMD onboard audio. Whether or not having ACS enabled in kernel behaves the same. After bsod, the VM can no longer locate the audio device even after reboot of the VM. My VM has the primary VGA (nvidia GTX1080), audio (AMD...

Any news about the new AMD p-state kernel driver that we can test? We have got pretty bad performance per watt on AMD platform.

Now I have tested using vGPU on 1050ti, and uses 1080 to complete passthrough to a single VM. It runs perfectly fine but needed to make sure to use a compatible version of driver (I used 460). Both host and client need the same version of driver for compatibility. It tested a 2GB vRAM profile...

and also to change the licence mode.

Now I am going to try another combination. I have a spare 1050ti and would like to use it for 4 x 1GB gpu for VM. And the main gpu to passthrough to a single vm. Problem is both are nvidia and blacklisting driver may be difficult.

I encountered error on a very basic operation. I created a zfs pool and created thin provision VM disk image on it. After some testing, I decided to remove the disks but show "dataset is busy" The storage is only being used for VM disk image. i.e. No iSCSI, No container. I tried reboot...

spent a whole night to risk my stable system and tested the vgpu unlock. In short, it works. My set up is 3900X + 128GB RAM + GTX1080 (single GPU) So I have to use the merge driver approach Before using vGPU my GPU is wholely passthrough to windows guest. With vGPU set up, I need to setup...

The top 10 rows refers to the 10 VM. It seems correct if counting the res column, but this does not match the report usage in GUI. 8627 root 20 0 17.2g 16.2g 15748 S 31.2 12.9 13050:41 kvm...

Is it normal to have a node reported usage of 85GB, while the total VMs + LCX memory usage sum to 40GB? I got these information from the summary under the DataCenter which has a single node only. Where I can have more information on physical memory assignment? I have around 10 VM + 4...

I did not assume OP must use hyper-v mode but removing hyper-v entrirely is extremely difficult if not impossible so it should always be assuming the hyper-v plays a role here.

@yurtesen This thread is about running vmware under windows, which utilize hyper-v in windows.

I set up a VM for live streaming on youtube. Since no hardware GPU, I uses software h264 encoding which is fine. On the audio side, if I have a console (SPICE) connected, everything goes very well. However, if this SPICE client is disconnected, audio will goes shutter. Doubling CPU / RAM make...

The UI is extremely confusing.. I just have my server shutdown by accident. Second question thing is meaningless just as the terms and condition of your credit card.

If you do mean the 0a:00.3 (usb) 0a:00.4 (Audio), its always the same and never change. There were issue in ryzen that require adding a commandline to disable flr or passthrough will crash the host. https://www.reddit.com/r/VFIO/comments/eba5mh/workaround_patch_for_passing_through_usb_and/ And...

Thanks again. Glad to know that the GPU will be fully reset after passthrough. I will try to clean install the client windows to see if it behaves differently. Anyway, the GTX1080 now can handle most gaming even in degraded performance. Except the MS flight simulator, of course.

I am using latest PVE on my ryzen platform with B550 chipset. I have my usb 3.x controller and onboard audio passthrough together with the single gpu. It is very strange that randomly my VM will not boot (or need to wait for like 5 mintutes to boot), until I remove, and re-add the same usb...

Thank you for your reply. May I specifically ask if blacklisting the driver has any effect on pass through? My observation is that if I blacklist nvidiafb, it seems to lower the gpu performance a bit. If I blacklist nouveau and nvidia, passthorugth simply wont work. And I would also like to...

Passthough should only work on full UEFI environment.

BIOS.. whats the impact? your error.

did you disable CMS support in BIOS?
