[one-users] VNC problem from Sunstone interface
Hi all,
I have a problem to start VNC session from Sunstone interface.
I have Ubuntu 12.04 Server with Opennebula 3.8.1 installed, the
newest version of noVNC (no error message), restarted oned,
sunstone-server and occi-server too.
After restarting, the python processes are:
oneadmin@myto-node:/usr/share/opennebula$ ps aux|grep
python

When I try to start VNC session from OCCI interface - everything
works, VNC session is established.
If I try to start VNC session to the same VM from SUNSTONE
interface, a message "Server disconnected (code: 1006)" occurs
immediately and python processes are changed:

Re: [one-users] SmartOS drivers
Hi Is it possible in one to have that type='xml' be type='json' to generate the machine description as Json rather, or would you recommend that the driver do the translation ? I am afraid not, you have to do the translation outside. Although it could be a nice feature to have [1]...

You may: 1 Copy the /var/lib/one/remotes/vmm/kvm folder to /var/lib/one/remotes/vmm/smartos and start working from there. 2 Add the driver to the oned.conf file VM_MAD = [ name = vmm_smartos, executable = one_vmm_exec, arguments = -t 15 -r 0 smartos, default= vmm_exec/vmm_exec_kvm.conf, type = xml ] 3 Any time you modify the driver you need to copy it to the hosts, so do not forget to execute onehost sync A couple of additional notes: 1 Actions are executed remotely on the target host, if you want to execute them in the front-end use the -l option in configuration. There are examples in oned.conf 2 The xml type will generate a XML file with the domain description as $1 for the deploy script. This is the real work for the driver, translate the generic template in something specific to SmartOS 3 Initially you'll need to deploy the vms by hand, use onevm deploy. You need also to get specific information from SmartOS with an Information Driver, that can come as a second step. Please keep us updated with your progress and don't hesitate to ask for help.

Re: [one-users] using PXE to boot xen hvm
Hi, Here, we are using a home-made PXE script that create partitions and do a bootstrap of a standard OS (Debian and Centos). Then all package install and configuration is done by CFengine. SystemRescueCD is a good choice, and easily PXE bootable, but we had some trouble with it, especially with odd hardware ( unrecognized NIC or RAID controler.) A few years ago, I used partimage. It work well and consume less space than a simple dd. Also, using IPMI over LAN could be interesting to manage hardware servers as virtual machines. Although a configuration manager like CFengine or Puppet is mandatory for a cloud, I think it's out of scope for integration in OpenNebula. Deploy a custom image, OS independant, (with the same system as vm?) seems to be a simple way and facilitate integration with existing infrastructure. Cheers, Nicolas AGIUS PS: We are using Centos 5 for Xen hosts, with backported kernel from SUSE, because openSUSE life-cycle is really too short for us. --- En date de : Mar 6.11.12, Jaime Melis jme...@opennebula.org a écrit : De: Jaime Melis jme...@opennebula.org Objet: Re: [one-users] using PXE to boot xen hvm À: Steve Heistand steve.heist...@nasa.gov Cc: Users OpenNebula users@lists.opennebula.org Date: Mardi 6 novembre 2012, 0h19 Hello Steve, This is a very interesting email, mainly because one of the upcoming features we want to deliver with the next release of OpenNebula is integration with bare metal provisioning systems. So, I'd like to take this opportunity to ask for more opinions from the community about this feature.

For the moment, let me describe you what we do internally at OpenNebula to address this problem. - Manually install the bare metal system (once) and configure it: - network dhcp - remove persistent udev rules - configure hypervisor - oneadmin user, ruby, and the rest of opennebula dependencies - add SSH keys - etc- Restart the server and boot from system rescue cd [1] - Backup the system installation by doing 'dd|gzip' of the disk drive over NFS to our NAS Once that's ready we deploy with a small webapp internally developed utility that does the following: - the webapp configures the tftpboot so that the server will boot a system rescue cd over pxe - once when the system rescue boots it automatically executes an autorun script [2] that is dynamically served by http by the webapp wich contains the command to dump the backed up image to the disk. (I'm happy to share more configuration specific details) As you can see this has a few shortcomings, the most important one being that we aren't using kickstarts, basically because we want to cover all the OS.

Re: [one-users] VNC problem from Sunstone interface
Any chance the "Use Secure WSS" is checked in sunstone config? Can you check/uncheck and retry with it unchecked just in case?Otherwise, kill your sunstone proxy and restart it manually:python /usr/share/opennebula/websockify/websocketproxy.py --target-config=/var/lib/one/sunstone_vnc_tokens 29876and see if it says something interesting to the console when you are trying to connect to the VM.HectorOn Wed, 07 Nov 2012 08:01:52 +0100, Jan Benadik jan.bena...@atos.net wrote: Hi, here are my python processes in different situations: 1. sunstone and OCCI server stopped oneadmin@myto-node:~$ ps aux|grep python oneadmin 1395 0.0 0.0 9516 912 pts/0 S+ 07:48 0:00 grep python nova 5838 0.0 0.2 118608 23796 ?

Re: [one-users] GlusterFS on open nebula
We use glusterfs with open nebula on two kvm nodes with mirroring with 6 bricks per node. We recommend gluster 3.3 with a back end network connection, 10GbE or IB. For stress testing the file system you can use dbench on a cluster of VMs. Gluster 3.2 wasn't very robust to node failure but 3.3 is far more stable. I would say its ready for development lab use and moderately heavy loads. For best performance, I would suggest using cgroups to shield the glusterfs processes from the kvm processes or use separate storage hosts.

Re: [one-users] mooseFS OpenNebula integration
look at glusterfs for mirrored storage configurations, its been very stable for us since 3.3 and you don't need any special transfer drivers. standard file system will suffice.

Great! I'm sure OpenNebula will work with the shared network driver, but the book states an optimized shared transfer manager [1] - unfortunately quite outdated. Is anybody working on migrating that for 3.8? That driver in reality isn't doing anything special: it just use the mfsmakesnapshot command instead of the classic cp -r to speed-up cloning operations (lazy copy operation). I was planning to update that driver this weekend, but you can also use the standard shared driver, it will work without problems. -- Giovanni Toraldo http://gionn.net ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org -- Jaime Melis Project Engineer OpenNebula - The Open Source Toolkit for Cloud Computing www.OpenNebula.org | jme...@opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
