[EDT] [hwsim/vm Error] Cannot open root device "root" or unknown-block(0,0): error -19

[Rahul Jain]

hello,

I am trying to execute vm-run.sh on Ubuntu-14.04 having 3.10 kernel.

I am getting below error:-
-----------------------
[    0.491374] VFS: Cannot open root device "root" or unknown-block(0,0): error -19 
[    0.492342] Please append a correct "root=" boot option; here are the available partitions:
[    0.493398] 0b00         1048575 sr0  driver: sr
[    0.494018] Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)
-----------------------

Kernel Command line is
Command line: mac80211_hwsim.support_p2p_device=0 mac80211_hwsim.channels=1 mac80211_hwsim.radios=6 init=/home/Perforce/OSS/hostap/tests/hwsim/vm/..//vm/inside.sh testdir=/home/Perforce/OSS/hostap/tests/hwsim/vm/../ timewarp=0 console=ttyS1 root=/dev/root rootflags=trans=
virtio,version=9p2000.u ro rootfstype=9p EPATH= ARGS=


Any suggestions on how to fix this error?

Thanks
