[Bug 1879175] Re: GVTd not working (black screen) after upgrade to qemu-5.0.0
No problem, thanks for getting the issue resolved! As a note, i've been going by this guide here from Intel. They seem to describe as that GVT-d refers to the concept of attaching a "whole" GPU to a single VM through PCI PT and it has two modes of operation, "Legacy" and "UPT". https://github.com/intel/gvt-linux/wiki/GVTd_Setup_Guide#561-create- gvt-d-kvm-vm -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1879175 Title: GVTd not working (black screen) after upgrade to qemu-5.0.0 Status in QEMU: New Bug description: Hi QEMU team, === Problem Summary === I have recently upgraded from QEMU-3.1.0 to to QEMU-5.0.0 on Debian Unstable.
