Hi,
I have trying to use the virtio-9p for my linux in QEMU, but without success.
Here is my option for booting my qemu:
i386-softmmu/qemu -kernel bzImage -append "console=ttyS0 video=uvesafb:ywrap,overlay:rgb16,address@hidden root=/dev/nfs rw nfsroot=10.0.2.2:/root,udp ip=10.0.2.16:::::eth0:none 5" -net nic,model=virtio -net user -soundhw all -usb -serial telnet:localhost:1200,server -vga std -m 512 -L ./pc-bios -bios bios.bin -virtfs local,path=/home/dallas/nfs,security_model=passthrough,mount_tag=v_tmp
The virtio network is working, I could mount the nfs through virio net.
And in the guest linux, I tried to mount v9fs by using following command:
mount -t 9p -o trans=virtio -o debug=0xFFFF v_tmp /mnt
but unfortunately I got the error:
mount: mounting v_tmp on /mnt failed: No such device
And I can't find the v_tmp neither in /sys/devices/virtio-pci/virtio1/ nor in /sys/bus/virtio/drivers/9pnet_virtio/virtio1/
And before building the kernel, I enabled the Plan 9 Ressource Sharing Support under File System/Network File System, I also enabled the following configures:
PARAVIRT_GUEST:
-> Processor type and features
-> Paravirtualized guest support
LGUEST_GUEST:
-> Processor type and features
-> Paravirtualized guest support
-> Lguest guest support
VIRTIO_PCI:
-> Virtualization (VIRTUALIZATION [=y])
-> PCI driver for virtio devices
VIRTIO_BLK:
-> Device Drivers
-> Block devices (BLK_DEV [=y])
-> Virtio block driver
VIRTIO_NET:
-> Device Drivers
-> Network device support (NETDEVICES [=y])
-> Virtio network driver
Would you please help me to find out the problem why I couldn't mount the v9fs?
Thank you very much!
BR,
Dallas
