Hello Community,<br><br>I am performing a fresh install of OpenNebula 3 on Ubuntu 12.04.1 for testing and learning purposes. I'm using the distro packages. I think the installation is OK, the problem are the configuration files for the images, networks, virtual machines, etc. I want to use a qcow2 image of Ubuntu created by ubuntu-vm-builder. Is it possible? I'll repeat the steps that I took for the sake of completeness. <br>
<br>I'm using Ubuntu 12.04.1. For this testbed, I'm using a single machine that will act as the controller and single host. The network bridge is configured properly like this:<br><br>auto br0<br>iface br0 inet static<br>
address 192.168.1.50<br> network 192.168.1.0<br> netmask 255.255.255.0<br> broadcast 192.168.1.255<br> gateway 192.168.1.1<br> dns-nameserver 8.8.8.8<br> bridge_ports eth0<br> bridge_fd 9<br> bridge_hello 2<br>
bridge_maxage 12<br> bridge_stp off<br><br>As you can see, it's a local network installation. I installed the OpenNebula packages with apt-get:<br><br>root@netune:~# apt-get install opennebula opennebula-node opennebula-tools opennebula-common<br>
<br>Now as 'oneadmin', I added 'netune' (my machine) as the sole host:<br><br>oneadmin@netune:~$ onehost create netune im_kvm vmm_kvm tm_ssh dummy<br>ID: 5 <br>oneadmin@netune:~$ onehost list<br> ID NAME RVM TCPU FCPU ACPU TMEM FMEM AMEM STAT<br>
5 netune 0 200 173 200 1.9G 596.6M 1.9G on<br><br>I also configured SSH to allow login without password. After that, I created a virtual network:<br><br>oneadmin@netune:~$ cat vnet01.template <br>
NAME = "LAN"<br>TYPE = FIXED<br>BRIDGE = br0<br>LEASES = [IP=192.168.1.246]<br>LEASES = [IP=192.168.1.247]<br>LEASES = [IP=192.168.1.248]<br>oneadmin@netune:~$ onevnet create vnet01.template <br>ID: 6<br>oneadmin@netune:~$ onevnet list<br>
ID USER GROUP NAME TYPE BRIDGE LEASES<br> 6 oneadmin oneadmin LAN F br0 0<br><br>Now, the creation of the OS image. As I mentioned before, I used the ubuntu-vm-builder command:<br>
<br>root@netune:~# ubuntu-vm-builder kvm precise --domain ubuntuvirtual --dest ubuntuvirtual --arch amd64 --hostname ubuntuvirtual --mem 256 --user storm --pass storm --ip 192.168.1.246 --mask 255.255.255.0 --net 192.168.1.0 --bcast 192.168.1.255 --gw 192.168.1.1 --dns 8.8.8.8 --mirror <a href="http://ubuntu-archive.locaweb.com.br/ubuntu">http://ubuntu-archive.locaweb.com.br/ubuntu</a> --components main,universe --addpkg acpid --addpkg vim --addpkg openssh-server --addpkg avahi-daemon --libvirt qemu:///system ; <br>
(lots of output)<br>root@netune:~# ls ubuntuvirtual/<br>tmpfpcs0v.qcow2<br>root@netune:~# cp ubuntuvirtual/tmpfpcs0v.qcow2 /tmp/ubuntuvirtual.qcow2<br>root@netune:~# ls -l /tmp/ubuntuvirtual.qcow2 <br>-rw-r--r-- 1 root root 627834880 Out 31 16:35 /tmp/ubuntuvirtual.qcow2<br>
<br>Executing 'kvm /tmp/ubuntuvirtual.qcow2' brings the virtual machine up with kvm, all the configuration passed as parameters for ubuntu-vm-builder are built into the image. After that, I registered the image for OpenNebula:<br>
<br>oneadmin@netune:~$ cat image01.template <br>NAME = "Ubuntu"<br>PATH = /tmp/ubuntuvirtual.qcow2 <br>TYPE = OS<br>PUBLIC = YES<br>DESCRIPTION = "Ubuntu basic installation"<br>oneadmin@netune:~$ oneimage create image01.template <br>

<br>The screen capture is on the link below. What I see is that the system does not find a bootable device. The message is very clear: "No bootable device." <br><br><a href="http://tinypic.com/r/2uqoeia/6">http://tinypic.com/r/2uqoeia/6</a><br>
<br>Question:<br><br>1) Can I use a qcow2 image created like described above?<br>2) Is the file vm01.template correct?<br><br>Thanks for your attention.<br><br>[]'s<br><br><br><br><br>
