Regarding issues with when unplugging thunderbolt after boot, this is due to PCI hotplugging being disabled (for obvious security reasons) - more details here https://github.com/QubesOS/qubes-issues/issues/1673 @Jim: following awokd's procedure you should be able to get UEFI working, also the configuration that I described for installation and post-installation were tested with UEFI only Now if you reboot and the PCI devices served by the thunderbolt/usb-c are not present anymore, you'll have to manually remove them from the list of pci devices that are passed through to your NetVM or UsbVM. Same for when you boot with the thunderbolt attached, you'll have to reattach the pci devices to the VM for passthrough. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
