Hello. I would like to pass the integrated gpu from the host os (ubuntu 20.04) to the windows 10 guest os with xen. This is because xen works great for me,better than qemu-kvm for my specific needs and because I have only two graphic cards. The nvidia rtx 2080 ti that I have already passed to the guest,and the intel UHD 630,that can be duplicated from the host to the guest so that it can be used in both places without interruptions. So I'm trying to build this repository :
https://github.com/intel/gvt-linux/wiki/GVTg_Setup_Guide#332-build-qemu--xen-for-xengt I have to say that this guide is totally not very well written. And the code is full of unpatched bugs. It's a month that I'm working on that,trying to fix the bugs that are came out from the 2015 until today. This is not my job. This is my hobby. But,I need to activate the pass through for my integrated GPU so I don't to give up. I'm also very angry with those coders who do not do their job well and with those coders who do not respond to help messages. It is not enough to write good code to be a good programmer. It is also important to keep the documentation updated, to help those who cannot get the code to work. Anyway,I've documented every step that I did to make it work here : https://github.com/intel/gvt-linux/issues/168 right now I'm trying to fix the bug n. 434544,that you can see below.

Someone must help me, thanking me for all the efforts I am making to make work a code full of errors. I would also know if I can activate the passthrough of the intel integrated gpu using the precompiled xen-hypervisor package that's on ubuntu. Right now I tried to compile it from scratch because I've thought that it was a necessary step,as described on the guide. But Im not sure on this point. -- Mario.
