Bug#1017394: qemu-system-common: virtiofsd aborts with error: fv_panic: libvhost-user: Invalid vring_addr message

[Russell Coker]

Package: qemu-system-common
Version: 1:7.0+dfsg-7
Severity: normal

# /usr/lib/qemu/virtiofsd --socket-path=/vmstore/sock/doc -o source=/usr/share/doc -o cache=always --socket-group=kvm
virtio_session_mount: Waiting for vhost-user socket connection...
virtio_session_mount: Received vhost-user socket connection

fv_panic: libvhost-user: Invalid vring_addr message
#

I am trying out virtiofs, I run the daemon with the above options and run kvm with the below
options and when I try to mount the mountiofs filesystem it aborts. I am not certain that I am
doing it correctly (this is my first attempt and I have never had it work), but I am certain that
it's not supposed to just abort with such an error.
