Instead of relying on templates, I use the following files for
instantiating respective images. I assumed that adding TARGET variable in
DISK section would do the trick, but obviously I am missing something...
$ cat debian_new.one
NAME = debian
CPU= 1
VCPU = 2
MEMORY = 512
DISK = [ IMAGE_ID = 9,
target = sda ]
OS = [ ARCH = x86_64 ]
NIC= [ NETWORK_ID = 1 ]
FEATURES=[ acpi=no ]
GRAPHICS=[ type = vnc,
listen = 0.0.0.0 ]
RAW = [ type = kvm, data = serial type='pty' source
path='/dev/pts/3'/ target port='1'/ /serial ]
$ cat opensuse_new.one
NAME = opensuse
CPU= 1
VCPU = 2
MEMORY = 512
OS = [ ARCH = x86_64 ]
DISK = [ IMAGE_ID = 11,
TARGET = xvda ]
NIC= [ NETWORK_ID = 1 ]
FEATURES=[ acpi=no ]
GRAPHICS=[ type = vnc,
listen = 0.0.0.0 ]
Then, I instantiate the VM by issuing $ onevm create
{debian_new.one|opensuse_new.one}
The instance turns into running state, but VNC discloses the issue
depicted above.
BTW - as setting up OpenNebula is a part of my bachelor's thesis
(comparison of private IaaS clouds), I would say that in comparison to
other solutions such as OpenStack OpenNebula is very user-friendly in terms
of installation complexity. However, I do not understand why the images
provided in the marketplace do not have a compulsory template to them ;(
Thank you for any suggestions,

In fact in OpenNebula, even if you can do it, is not common to set the kernel or initrd for kvm VMs. On Fri, Mar 29, 2013 at 12:50 PM, Mark Farragher m...@firstfocus.eu wrote: Hi Jamie, I fixed the problem! I manually created a working virtual machine in virt-manager and then created another one through OpenNebula. After cloning the OpenNebula virtual machine in virt-manager I see its xml file appearing in /etc/libvirt/qemu and this allows me to do a side-by-side comparison of a working VM and a non-working one. One of the differences I spotted is that the OpenNebula virtual machine (which does not work) has this line: KERNEL = /vmlinuz The working virtual machine does not specify a kernel. So I edited the cloned OpenNebula xml file and took this line out, restarted the libvirt daemon and rebooted the virtual machine in virt-manager. And it worked! I traced the setting to the /etc/one/vmm_exec/vmm_exec_kvm.conf file in the front end. I commented the KERNEL line out and restarted the opennebula daemon. From that point onward every virtual machine I create in OpenNebula works! My theory is that by specifying the kernel the VM boots into a kernel that does not have virtio support. So once the bootloader finishes it does not see any bootable device and halts. By omitting the KERNEL parameter I let KVM automatically pick the right kernel.

In the PROLOG phase I can see 11 GB being transferred from the front end to the host. I also tested with another virtual machine, like this: 1. I manually created a new VM on the host in virt-manager 2. I booted the VM, connected over the network using SSH, installed some software in it and verified that everything is ok. 3. I then copied the image file of this working vm (30GB) to the front end and created an OpenNebula image with it 4. I tried to boot a new VM in OpenNebula using this image. This gives the exact same error. Isn't it strange that two unrelated disk images both get corrupted in the same way as soon as I put them in OpenNebula? My OpenNebula version is 3.6.0 and my host OS is: oneadmin@Pinky:/opt/one/datastores/0$ cat /etc/issue Debian GNU/Linux 6.0 \n \l oneadmin@Pinky:/opt/one/datastores/0$ uname -a Linux Pinky 2.6.32-5-amd64 #1 SMP Mon Feb 25 00:26:11 UTC 2013 x86_64 GNU/Linux My front end OS is the same : oneadmin@metroplex:/etc/one$ cat /etc/issue Debian GNU/Linux 6.0 \n \l oneadmin@metroplex:/etc/one$ uname -a Linux metroplex 2.6.32-5-amd64 #1 SMP Mon Feb 25 00:26:11 UTC 2013 x86_64 GNU/Linux Is it possible the images are okay and the full 11GB is transferred, but the booting VM is somehow unable to deal with lvm partitions and therefore only sees the boot partition? Do I need to install or upgrade something to get lvm support in kvm working?

The Image is not correctly downloaded, its size is 200 Mb instead of 11 Gb. I've also been digging on what could be block device major 254 and it may be an lvm partition. 200 Mb is enough to hold the boot loader and the boot partition but not the root partition, so it crashed. It is strange that you had no error downloading that image. Can you tell me the OpenNebula version and frontend distribution to test this here?

[one-users] econe auth not working (4.0 and 3.8.3) ?
Hi there, On both 3.8.3 and 4.0 I'm getting the following error when trying to use the EC2 API: - AuthFailure: The username or password is not correct I'm using ACCESS_KEY = username, and EC2_SECRET_KEY= sha1 password, shown with oneuser show id . I'm pointing EC2_URL to http://one controller:econe port. My ec2_auth has the correct serveradmin credential. My users are using Core as the auth driver, and were created with Sunstone.

Re: [one-users] econe auth not working (4.0 and 3.8.3) ?
Hi,
I will answer my own question, because I find the solution.
The problem was that I was using the fqdn instead of the IP address, for the
EC2_URL.
I had a look at the EC2CloudAuth.rb, and what was happening was the following:
- The signature_v1 function requires the host to be stripped from the params.
- The current implementation only deletes the host name that matches the :host:
parameter from econe.conf (params.delete('econe_host'). )
- So, signature_v1 would consider the host for the calculation when I was using
the fqdn != :host:
I had the IP as the :host: parameter. As soon as I changed it to the fqdn, I
could use http://fqdn:econe port as the ec2 endpoint.
But then, http://ip:econe port stops working.
Regards,
Ricardo

Re: [one-users] [Docs] Problem with OpenVSwitch and some questions about Ceph
Hello, I know that previous versions of opennebula required openvswitch-brcompat http://opennebula.org/documentation:rel3.8:openvswitch#hosts_configuration but the 4.0 docs seem to indicate that with KVM brcompat is not required: http://opennebula.org/documentation:rel4.0:openvswitch#ovswitch_and_ovswitch_brcompat Anyway, I did install the openvswitch-brcompat package, but got the same error. (looking at the docs now, it seems that you have to tell the OpenNebula to use a different openvswitch driver, specifically openvswitch_brcompat, so I think this test may have been incomplete) Then I attempted to run the ovs command at the command line, when I do so, I get the following error: root@loki:~# sudo /usr/bin/ovs-ofctl add-flow ovsbr0 in_port=,dl_src=02:00:44:47:83:44,priority=4,actions=normal ovs-ofctl: dl_src=02:00:44:47:83:44: bad syntax for in_port I think this might be the root cause of the issue? Where is in_port defined? I don't see it in the onevnet template, but that doesn't mean I didn't just miss it. One other question I had while going through the docs again, I see on the openvswitch page: The sudoers file must be configured so oneadmin can execute ovs_vsctl in the hosts. How do you recommend doing this? I thought the oneadmin was set up to execute commands with sudo when installing the packages... I didn't see the oneadmin user in any of the sudo groups (sudoers, wheel, root) so I added the I did add the oneadmin user to the sudo group also without any success: root@loki:~# addgroup oneadmin sudo Adding user `oneadmin' to group `sudo' ... Adding user oneadmin to group sudo Done. The only thing else I can think to do would be to set no passwords in the sudoers file: oneadmin ALL=NOPASSWD: ALL But this seems less than ideal. Also, I think the incorrect syntax is the root cause of the issue, if there are other issues. What steps can I try next?

With regard to the /usr/share/opennebula issue, I'm afraid that's because of the Debian/Ubuntu packaging policy. For other distros (CentOS and openSUSE for example) the path is the one that appears in the documentation. To makes things easier for users I think this should be reflected in the README.debian file, and in the platform notes in the documentation. So thanks a lot for pointing this out.
