What mode are you using for the VM?

Does only the VM crash or the entire systen?

VM is on i915-GVTg_V5_4.

BIOS is OVMF

Machine i440fx-5.1

 

The VM crashes and it crashes the vm manager. i can ssh into my linux vm's but cant go under vm tab i unraid. and if i type "/etc/rc.d/rc.libvirt stop" in terminal on unraid it fails. if i try restart unraid server it fails because it cant stop libvirt service. only way i can restart or shutdown the unraid server is by holding shutdown button on server for 10seconds.

Is anything running in the VM in the background that uses the iGPU?

This is a common issue when more VRAM is used than allocated in the GVT-g mode because it tries to allocate memory where no memory is available.

No not. only use the Firefox and microsoft office on that machine.
It just happened again and here is the log from unraid:

That is such a message when the VM try to allocate memory when no VRAM is available.

 

On Github there are many issues open with similar errors but no real solution to this.

The main issue is that are only 256/512MB available and this is by today standards really not that much.

Okey, then there is nothing i can do?

Do you know why i only can select:

i915-GVTg_V5_4
i915-GVTg_V5_8

and not i915-GVTg_V5_1 ?

Sadly enough no...

This is because most motherboard manufacturers haven't implemented the aperture size or better speaking they haven't enabled so that a user can change the aperture size for the iGPU.

 

You can go to your BIOS and see what options you got for the iGPU.

i can set memory size to 1024mb and then there is a setting called "Above 4G Decoding" ? dont know what that is?

When will I update the 11th generation Intel AGPU. After I upgraded the CPU, I found that it can't work anymore, which is very distressing. What is the specific reason why the 11th generation CPU is not supported, please tell me if there is still a chance to continue to use it on the 11th generation? Otherwise I will replace 9900k
