List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: qemu-devel@nongnu.org, Eric Van Hensbergen So on the host side I'm trying to do this: $ qemu -cpu pentium3 -nographic -no-reboot -kernel bzImage \ -hda hda.sqf -append 'root=/dev/hda rw init=/sbin/init.sh panic=1 \ PATH=/bin:/sbin console=ttyS0 HOST=i686 ' -net nic,model=e1000 \ -net user -virtfs local,path=../root-filesystem-i686,security_model=mapped,mount_tag=root And on the guest side I'm trying to do this: mount -t 9p -o ro,trans=virtio,version=9p2000.L root /mnt And it's saying: mount: mounting root on /mnt failed: No such device No idea what I'm doing wrong, "no such device" is not an informative error message. There's no obvious way to get the Linux client to tell me what tags are available. "What can I mount? Do you see anything?" I've looked under /proc and /sys for "virtio"... It's entirely possible I'm missing something in my kernel .config but who knows what? I note that qemu was sitting down and SULKING unless I specified the security_model (I'm mounting read only, I don't care, but there doesn't seem to be any way to DO a read-only export). I'm guessing based on the fact it stopped complaining that it is in fact exporting something (and thus not upset I gave it a relative path, although giving it an absolute path made no difference...) Any clues? Rob
