With this command line, qemu (or seabios) will try to boot off vhost-user-fs-pci device but will most likely fail. I dunno why it tries to boot out of unsupported device, but this is what it does for me anyway, unless I also add `bootindex=-1' to this device (to exclude it from boot). Or if I move -drive line before vhost-user-fs-pci line, it also boots out of "kvm_laptop.img" device, the same way as with adding bootindex=-1. So I don't know once again how you actually start this. And it just works for me after rearranging boot order in the above command line. Seabios, as far as I can see, does not have any support of virtiofs whatsoever, neither older nor last one. Seabios 1.16.3 does not have changes related to virtio or vhost, it's mostly a bugfix release, so I've no idea how you managed to relate this issue at hand with seabios update. I don't know what to do here. /mjt
