I am trying to setup virtfs using KVM and QEMU.


  1.  Inside the VM, I do
     *   mount -t virtiofs myfs /dev/myfile  --succeeds
     *   cd /dev/myfile  -hangs


  1.  The host logs -

 qemu-system: Failed to write msg. Wrote -1 instead of 20.
May 24 14:01:08 device-myhost[644]: qemu-system: vhost_set_vring_kick failed: Invalid argument (22)
May 24 14:01:08 device-myhost[644]: qemu-system: Failed to set msg fds.

May 24 14:01:08 device-myhost[644]: qemu-system: Failed to read from slave.


  1.   Qemu parameters -

 "-device",
    "vhost-user-fs-device,queue-size=1024,chardev=char0,tag=myfs",
    "-object",
    "memory-backend-memfd,id=mem,size=4G,share=on"

Any input is appreciated...

Thanks
