OVP-427 : qemu build does not enable virtfs support.

Created: Dec 10, 2013 Updated: Mar 11, 2016

Resolved Date: Dec 13, 2013

Found In Version: 5.0.1

Fix Version: 5.0.1.11

Severity: Severe

Applicable for: Wind River Linux 5

Component/s: Kernel

Description

In the latest build, qemu does not have virtfs support.  The following error is printed out and qemu fails to boot:

qemu-system-x86_64: -virtfs local,path=/var/run,security_model=none,mount_tag=test_mount: Parameter 'driver' expects device type

This occurs when virtfs support is not enabled in qemu.

Steps to Reproduce

qemu-system-x86_64  -nographic -k en-us -m 2048  \
        -name GUEST_A \
        -net none \
        -enable-kvm\
        -kernel /images/bk.bzImage \
        -append 'root=/dev/vda ro console=ttyS0  selinux=0 enforcing=0' \
     	-virtfs local,path=/var/run,security_model=none,mount_tag=test_mount \
        -drive file=intel-xeon-core-ovp-kvm-preempt-rt-dist.ext3,if=virtio,cache=none

If that succeeds, on the guest:
mkdir -p /tmp/shared
mount -t 9p -o trans=virtio test_mount /tmp/shared/ -oversion=9p2000.u
