Greetings!
Howdy to you all from this new member of the forum, and a new convert to Linux! :)..
After researching for a while, I am very much interested in KVM, especially since it allows to pass through hardware to client OSs (also one of the reason why I convert..) Anyways, as the title suggests, I am trying to pass a GPU to Windows 10 client but unfortunately with no success.
I have a Lenovo G510 laptop with the following configuration:
My /etc/modules looks like:
My GRUB setting looks like:
My /etc/modprobe.d/vfio.conf looks like:
I added
to my /etc/modprobe.d/blacklist.conf.
Not to forget the following steps:
And, after running sudo update-initramfs -u, dmesg | grep vfio looks like
And sudo lspci -vv shows
The following is my QEMU script to my Windows 10 client #1:
The following is my XML configuration for my WIndows 10 client #2:
Both of these VMs recognize the AMD Radeon, as Graphic Device, but only with Error Code 43.
I tried these and those, I even use a customized kernel, just to enable DMA remapping option, which in default kernel was disabled. Am I missing something? Do my hardware support passthrough? Is there someway I can do to check (both in host or in clients) if everything is OK? Does it have any connection to vgaswitcheroo because of the switchable graphics? If so, using my modified kernel, I get the following error:
I appreciate all help and guidance. Any further online resources will also be a great help. Many thanks!
Cheers!
