Hi Team,

I need some help to setup instance tunnel.

I tried 2 node installation today and successfully added new compute1 node.

Later i have created new VM on new compute1 node. It successfully spawned
but the issue is it couldn't get dhcp ip.

Due to this eth0 is not assigned with an IP address. I think instance
tunnel interface is not correct.

Currently I set IP to automatically created interface br-tun, do i need to
create new instance tunnel?

br-tun Link encap:Ethernet HWaddr 6a:65:2d:ed:90:44
inet addr: Bcast: Mask:
inet6 addr: fe80::98c7:a1ff:fef6:bcd7/64 Scope:Link
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:8 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 B) TX bytes:648 (648.0 B)

And given this Ip addres( in [mvs] configuration

local_ip =
tunnel_type = gre
enable_tunneling = True

Is it correct? Please help me.
