[one-users] SSH to VM subnetwork problem

[Giuliano Casale]

Hi all,

I have a working installation of OpenNebula 3.8.3, but despite many
efforts I still cannot ssh from the host into the VMs.

All hosts have:
- an eth0 interface listening to the internal network of my institution
- an eth1 interface for a private switched LAN only between the hosts
that compose the OpenNebula cloud. The hosts have IPs 10.0.0.X on this
network.

On all the machines I have run the following commands:

brctl addbr br1
brctl addif br1 eth1
ifconfig eth1 down
ifconfig eth1 0.0.0.0 up
ifconfig br1 10.0.0.X/24 up    (where X=1,2,... depending on the host).

I then defined in Sunstone a virtual network as follows:
=============
ID             : 0
NAME           : vn-private
USER           : oneadmin
GROUP          : oneadmin
CLUSTER        : cluster
TYPE           : RANGED
BRIDGE         : br1
VLAN           : No
PHYSICAL DEVICE:
VLAN ID        :
USED LEASES    : 2

PERMISSIONS
OWNER          : um-
GROUP          : ---
OTHER          : ---

VIRTUAL NETWORK TEMPLATE


RANGE
IP_START       : 192.168.100.1
IP_END         : 192.168.100.128

USED LEASES
LEASE=[ IP="192.168.100.13", MAC="02:00:c0:a8:64:0d", USED="1", VID="14" ]
LEASE=[ IP="192.168.100.37", MAC="02:00:c0:a8:64:25", USED="1", VID="41" ]
=============

Now: using VNC, I see that the two VMs .13 and .37 can correctly ping
each other.However, if I login to any host and do 'ssh
root at 192.168.100.13' it does not connect to the VMs.

I tried then 'route add -net 192.168.100.0 netmask 255.255.255.0 dev
br1' and 'route' shows correctly

Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.100.0   *               255.255.255.0   U     0      0        0 br1

but still ssh does not work.

Can someone help me? My ultimate goals are:
1) to be able to ssh from the host into the VMs.
2) if possible, give internet connectivity to the VMs through eth0.

Thanks,
Giuliano
