Hmm...That's strange. I just test PXE boot again with GPU mounted, but this time is successful (using Tesla P4). And QEMU version still 2.11. But previously it's not working. Perhaps the OS was not doing system update yet at previous installation. I'll take looking at this. Sorry about bothering.

Hi Alex, Here's VM profile. Basically this VM is created from virt-manager, and guest OS is Ubuntu so no need to add capabilities for Windows environment. https://pastebin.com/VZM63ZsC And GPU for this VM is Tesla P100. But we also found the same issue on another GPU which is Tesla P4. Eddie
