Hi All. I have the following set up: * Host : Ubuntu-16, on a amd64 hardware * Guest : Ubuntu-21, as a VM on QEMU/KVM. Now, I have a SD-MMC card-reader attached physically on the host, which is listed as expected if I do lspci on the host : ############################################ ajay@ajay-Latitude-E6320:~/ldd3$ lspci .... .... 0a:00.0 SD Host controller: O2 Micro, Inc. OZ600FJ0/OZ900FJ0/OZ600FJS SD/MMC Card Reader Controller (rev 05) .... ############################################ However, if I try doing lspci on the guest, this pci-device is not listed. So, I have the following queries : * Would it require enabling pci-passthrough (if not already) in the guest-kernel, on a global basis? * Does having raw-physical-access on the guest, require support from the pci-device itself? My ultimate aim is to get the sd-mmc-driver that I wrote for the host-machine, to run unmodified on the guest-machine (obviously after the sd-card-reader is detected on the guest, and the code recompiled on the guest). Will be grateful for any pointers. Thanks and Regards, Ajay
