I'm a bit nervous about our testing missing some conversion, so we'll need qemu patches for PCI so we can test on other platforms too. The devices I looked at (blk and net) are probably OK as ccw needs to convert always. I agree that we want to test on other platforms as well, but unfortunately I not familiar enough with other platforms to feel confident enough to convert virtio-pci and test it :( ___ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
