dgaschk Posted September 21, 2019 Share Posted September 21, 2019 The VM works until I try to add a Nvidia card as a second GPU. This line fills the syslog: Sep 20 21:34:09 rack kernel: vfio-pci 0000:65:00.0: BAR 1: can't reserve [mem 0x38bfe0000000-0x38bfefffffff 64bit pref] rack-diagnostics-20190921-0449.zip Quote Link to comment
dgaschk Posted September 21, 2019 Author Share Posted September 21, 2019 This seems to fix the problem. VNC did not connect at first but rdp and splashtop did. VNC worked after I logged in once. https://www.redhat.com/archives/vfio-users/2016-March/msg00088.html Windows 10 VM on Supermicro X11SPM-F with GeForce RTX 2080 SUPER appears to be working. VNC is not usable but splashtop works well. I passed the GeForce through using Syslinux configuration with "{append initrd=/bzroot} vfio-pci.ids=10de:1e81,10de:10f8,10de:1ad8,10de:1ad9" I installed newer nvidia drivers and chose the nvidia card as primary GPU. No ROM BIOS file is needed Quote Link to comment
dgaschk Posted September 22, 2019 Author Share Posted September 22, 2019 After further testing weirdness ensues. I rebooted in safe mode and back to normal mode. The BIND from vfio-pci.cfg is working correctly and i am successfully using the stock Syslinux configuration. I still needed the following three lines in the go file for the VM to startup and not fill the syslog: #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 2 Quote Link to comment
