Hello everybody! Sorry if I posted in the wrong board, but I really did not know where it would fit.
Well, I've been on the wiki and read all about xen. There is no specific instruction on how I use the vga passthrough. So I went on the Xen wiki. I managed some clues of what to do. One is related to flags that should enable to run Xen.
http://wiki.xen.org/wiki/Mainline_Linux_Kernel_Configs
So I went on the arch wiki again. I read about how could recompile the kernel and install the new version of the same by pacman. Flags activated, many hours of compilation. The build of the new kernel was installed and ready.
I installed the package XEN located in AUR. I noticed that it downloads a kernel with XEN name. There in the arch wiki as well as in the xen wiki, which is necessary to modify the grub boot to do this special XEN kernel. I made the change. Researched how the procedure could be done to vga passthrough, but it did not work.
So i realized that there are two possibilities to run a virtual machine.
1 - Using XEND
and the other used when boot the XEN kernel.
2 - (xenstored, xendomaind, and some others I've forgotten at the moment)
Option 2 is not possible to use it when using the vanilla kernel (even after the change of flags) but in the arch wiki is saying that the vanilla kernel is already suffcient to run xen, but because the xen package in AUR downloads an extra called xen kernel?
A i'm using a notebook with an NVIDIA 630M, so i've bumblebeed running here. If more info is need, just ask and i'll post. I really really need to test this vga passthrough working on :'/
here are some links that i've been reading
http://wiki.xen.org/wiki/Xen_PCI_Passth … assthrough
http://wiki.xen.org/wiki/Xen_VGA_Passthrough
http://wiki.xen.org/wiki/Xen_VGA_Passth … d_Adapters
http://wiki.xen.org/wiki/Secondary_GPU_Passthrough
here are some configs i've using
This is the virtual machine config. If this config i can boot normaly, but no VGA with NVIDIA. Em enable gfx_passthru, the machine cant boot. I've tryied do attach it do to PCI list via xl command, but not positive results. Xen always complain about the device cant be attached or what else
