Hi Khoa,

I had the same issues sometime back, so I have a hole list of things you
could try out (it should keep you busy for some time) :

- Are you able to ping the VM from the node? the frontend?

- Your eth0 inet addr is 172.29.70.137, so could you try adding another
vnet in which the leases are some free addresses within the same C class
LEASES=[ IP=172.29.70.138 ]
LEASES=[ IP=172.29.70.139 ]
then run a VM on this new VNet...

- Just to make sure that your network setup is correct, could you try
following this guide [2] to create a bridge interface over eth0, then
create another vnet in which BRIDGE = br0.

- Also, try installing virt-manager[1] on the node computer, and add
this to your VM template
RAW = [ type = "kvm",
              data = "<devices><serial type=\"pty\"><source
path=\"/dev/pts/5\"/><target port=\"0\"/></serial><console type=\"pty\"
tty=\"/dev/pts/5\"><source path=\"/dev/pts/5\"/><target
port=\"0\"/></console><graphics type=\"vnc\" port=\"5901\"
autoport=\"yes\"/></devices>" ]

virt-manager will list any running VMs and will let you open a console
on the VM to make sure it was assigned the correct IP address.

Oh, and though I like the name "Open netbula" and find it hilarious :) I
think it's rather called OpenNebula [3]
