error mount_tag in novm's guest #19

Closed zhurongze closed 9 years ago

zhurongze commented 9 years ago

CentOS 6.5 kernel 3.12.21 qemu-kvm 2.1.2 (enable-virtfs) go version go1.3.3 linux/amd64 Python 2.6.6

firstly, I run the novm, it print "9pnet_virtio: no channels available", so I modified lib/novm/libexec/init, it can print the mount_tag:

...... echo "~ read virtio1 mount_tag ~" > /dev/kmsg
cat /sys/bus/virtio/drivers/9pnet_virtio/virtio1/mount_tag > /dev/kmsg
echo "~ read virtio2 mount_tag ~" > /dev/kmsg
cat /sys/bus/virtio/drivers/9pnet_virtio/virtio2/mount_tag > /dev/kmsg
echo "~ read virtio1 status ~" > /dev/kmsg cat /sys/bus/virtio/drivers/9pnet_virtio/virtio1/status > /dev/kmsg ......

I run the novm again, it print the log: ......


�root~~~ read virtio2 mount_tag ~~~

init~~~ read virtio1 status ~~~
0x00000007
......

so, I think the mount_tag are error in guest, the correct mount_tag are "root" and "init" .

Sorry, I was a bit aggressive in pushing a change that broke some things.

This should be corrected in bb10cddf229361394fea4c0b7c895ba15663b925.
