[one-users] Cant´t create own working VM for OpenNebula

[Yilmaz Eldogan]

Hello,

I´m trying for 4 weeks to create an own working VM for OpenNebula 3.2, 
but my approaches haven´t been successful.

First I want to give you information about our subnet:
Subnet-Range: xxx.xxx.xxx.128 - xxx.xxx.xxx.192
Subnet-Mask: 255.255.255.192
Frontend: xxx.xxx.xxx.180
Node: xxx.xxx.xxx.179
Gateway: xxx.xxx.xxx.190
DNS: xxx.xxx.xxx.131
DHCP: xxx.xxx.xxx.134

I tried to deploy ttylinux (OpenNebula Example VM) and pinging and SSH 
is working without any problems. But my approaches to create a working 
Ubuntu/OpenSUSE VM that I can ping and connect via SSH haven´t been 
succcessful.
I have created many VMs. Downloaded the right contextualization file 
from here: 
http://dev.opennebula.org/projects/opennebula/repository/show/share/scripts. 

Of course I adapt the Gateway and Subnet-Mask part in the file to our 
subnet. I leave the context part in the template-file (to create VMs) 
empty.
In the VM, I link the downloaded and adapted context file, so the script 
is started every time the VM boots. The VM is deployed to the cloud 
properly, and it also gets in the "RUNNING" state.

But my major problems are that I can´t ping ("Destination Host 
Unreachable") or connect via SSH to them.

I tried these tutorials, but at the end of these approaches I´m getting 
the same errors:

https://portal.futuregrid.org/tutorials/opennebula
https://support.opennebula.pro/entries/20466331-using-suse-studio-with-opennebula


Any ideas, what I´m doing wrong ?

Here you can see my template file to create a VM in OpenNebula:

Name=UbuntuVM
CPU    = 0.5
MEMORY = 512
DISK   = [
SOURCE = "/var/lib/one/images/ubuntu.img",
target = "hda",
readonly = "no"]

NIC    = [ NETWORK ="cloud network" ]

FEATURES=[ acpi="no" ]


The virtual network "cloud network" is created via Sunstone web UI and 
contains the following IPs:
xxx.xxx.xxx.166
xxx.xxx.xxx.171
xxx.xxx.xxx.172
These are free IPs in our subnet.


Best Regards,

Yilmaz
