check that unraid is not using it with vesafb if booted in uefi mode

I am not in uefi mode... but i am curious how to check that?

Edited December 21, 20214 yr by mad9

Reistalled but before i test the passthrough, i found a miner problem that i can not shut down the vm properly.
It automaticly goes again to the boot menu and restarts

 

Any ideas?

This doesn't sound good and I never experienced such issue. From where you grabbed the opencore img?

Make sure your unraid system is ok.

Syslog reports "cannot write to memory region", you have black screen output but the vm is accessible, usually this happens when you use a single gpu, or when the gpu you are trying to passthrough is the primary gpu for unraid.

From the git. https://raw.githubusercontent.com/SpaceinvaderOne/Macinabox/84a82e54ae5f596f492ead2f2d98767029e2826a/bootloader/OpenCore.img.zip

Hi All.

 a little update after the holidays....

 

i tried a lot to make it run, and finally it works but not stable the screen freezes quite often.

 

I made it run with Unraid 6.10 rc2; UEFI Bios; modified "go" (see further down) and ghost82 instruction on q35-6.0

 

Now i need to find out how to make it more stable.

 

go file-->

#fix video for VM
echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind

added a part of the syslog:

You can try to add 

iommu=soft

in the append line of your syslinux config.

 

Freezes may depend on the bios of the gpu (in general msi cards can be quite problematic for mac os).

If I were you, I would try to add the bios of another brand gpu (same 6600 xt, but different vendor, same memory timings!) to the xml, like this:

https://www.techpowerup.com/vgabios/236559/asrock-rx6600xt-8192-210607

 

If it runs (I would say you have 50% probability...) I would let the case open to monitor that everything is ok, especially that the fans spins when the gpu is under some load.
