Hello Carlos and Everyonel
Thanks Carlos for your reply.
I was able to login into vm through vnc by Virtual machine manager provided
by suse and can see it running fine.
I could not get what you meant by vmcontext script . Is it the same as
init.sh script?
For me init.sh script is :
'if [ -f /mnt/context.sh ]; then
. /mnt/context.sh
fi
hostname $HOSTNAME
ifconfig eth0 $IP_PUBLIC
useradd -m $USERNAME
mkdir -p ~$USERNAME/.ssh
cat /mnt/id_rsa.pub >> ~$USERNAME/.ssh/authorized_keys
chown -R $USERNAME /home/$USERNAME
with VM template above shown .
and also i could not get
"Try to execute the vmcontext script as root, if the IP is then configured,
you may need to change the runlevel where you put it"
Also, the vm is getting some dynamic IP 10.112.19.218 when i assign it
10.112.10.38
So, the IP is not assigned properly.
Please guide for the same
Thanks and Regards
Ankit Anand
