Re: [one-users] ttylinux via ssh not accessible any more after migrate / suspend -> resume
Hi Viktor, that's a very interesting problem. Let's check if it's related to the bridge. Start the vm and execute 'brctl show' on one host. Migrate it to another host and execute 'brctl show' on that second host. Compare those outputs and check if libvirt/kvm is correctly attaching the network interface to the bridge. cheers, Jaime On Fri, Sep 3, 2010 at 12:54 AM, Viktor Mauch wrote: > hello javier, > > one more time, > > I'm now working with OpenNebula 2.0beta with the KVM Hypervisor (head node > and cluster nodes are based on 10.04).

Our development is sponsored by the state, thus everything we develop will be open sourced, and so, it'd be an honour to contribute this to the OpenNebula ecosystem. This is an ongoing development, and the TM driver is just a small part of it. On the other hand, in our environment it has been quite stable for a couple of weeks now, so I think it's time to do an alpha release. I'll use the weekend to gather all its dependencies, wrap it up and write some docs about it. Expect a release in the beginning of next week. Thank you for your interest.

Re: [one-users] Open Nebula unable to delete the snapshot of a VM
Hi Italo,
as you see, the VG_NAME is "images", not "/images".
Can you confirm that you have set:
VG_NAME=images
(and not: VG_NAME=/images)
in $ONE_LOCATION/etc/tm_lvm/tm_lvmrc
If you haven't done it, please do it, because it's the correct value.
If something else fails after that let's debug that other thing.
Cheers,
Jaime

[one-users] OpenNebula and Ubuntu Feisty
Hi all, I'm installing OpenNebula using some tutorials: [1] http://www.opennebula.org/documentation:archives:tp2:qg [2] http://www.opennebula.org/documentation:rel1.4:xeng [3] https://help.ubuntu.com/community/OpenNebula [4] http://www.opennebula.org/documentation:rel1.4:cg The front end is running Ubuntu Lucid (10.04) and everything went fine, but the node is running Ubuntu Feisty (7.04, mainly because of Xen). The problem is: the package opennebula-node is not officially available for Feisty (I think the oldest Ubuntu version that has official OpenNebula packages is Hardy (8.04)). I would like to know what this package opennebula-node really does. I mean, if it is a package that only creates some directories and sets up the oneadmin user, I can do that manually. If not (if there are binaries installed, for example), then I will have to make up a more sophisticated workaround. Thanks in advance, Nelson Mimura Gonzalez ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] OpenNebula and Ubuntu Feisty
Just FYI, I already set up SSH, NIS and NFS both at the front end and the node, and I also installed, configured and tested Xen at the node. I think that the only thing to be done at the node is to create the user oneadmin. But if you see [1] this is not necessary, as long as the /home directory (where SSH permissions are put) is shared through NFS. So the question persists: what does the installation of opennebula-node do? ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
[one-users] Hook for VM becoming UNKNOWN state
Hi, there, I would like to have a hook to run a script when the user shuts down the VM from inside the OS. When that happens, the VMState=ACTIVE and LCM_STATE=UNKNOWN. Is it possible to add this to the hook system of OpenNebula? Otherwise, which code should I look for to add some custom code after it gets into UNKNOWN? Thanks a lot. -- Shi Jin, PhD ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] What kinds of shared storage are you using?
We are using GlusterFS and it works great :) With some tweaking we were able to average around 90-120 megabits per second on reads and 25-35 megabits per second on writes. Configuration is as follows: 2 file servers: - Supermicro server motherboard with Intel Atom D510 - 4GB DDR2 RAM - 6 x Western Digital RE3 500GB hard drives - Ubuntu 10.04 x64 (on a 2GB USB stick) - RAID 10 File servers are set up with replication and we have a total of 1.5TB of storage dedicated to virtual machine storage with ability to grow it to petabytes on demand - just add more nodes!

Re: [one-users] Hook for VM becoming UNKNOWN state
Hi, The other thing we may want to look at is to detect that the VM is stopped in libvirt and move the VM to shutdown->epilog->done.

Re: [one-users] Hook for VM becoming UNKNOWN state
Thank you. That's useful information. I will keep watching this ticket. In the same time, could you please point me to the code where a quick hacky script can be inserted after OpenNebula detects UNKNOWN. Thanks. Shi On Fri, Sep 3, 2010 at 3:24 PM, Ruben S.
