Re: [one-users] Files in /var/tmp/one/vmm/kvm/ disappear.
Hello Richard, I'm not sure if this is related to OpenNebula, maybe there's some other daemon who's removing those files. Just to be sure it isn't OpenNebula, I suggest you audit that file to discover the PID of the process removing it: # install audit package # start the auditd daemon $ auditctl -w /var/tmp/one/vmm/kvm/deploy -p war -k opennebula_remotes wait for the unwanted delete to take place (you'll find the log in /var/log/audit/audit.log) Once you're finished do $ auditctl -W /var/tmp/one/vmm/kvm/deploy -p war -k opennebula_remotes # shut down the auditd daemon Regards, Jaime On Thu, Mar 8, 2012 at 11:37 PM, richard -rw- weinberger richard.weinber...@gmail.com wrote: Hi!

[one-users] Creating a VM Image
Hi there, I have been reading through the docs on how the vm's are created / deployed, and I must admit that I still can't quite get how it all fits together. If I want to create a vm - what is the best way to do this ? Ie: I have the CentOS 6.2 dvd image. I would like to build a Linux Base image that will then get extended by a template to be a DNS or DB or WEB server. I have used cobbler to do this on existing machine based installations with success, but I am trying to figure out how To do this with a VM deployment. When I create a filesystem, I use a raw image file. When trying a qcow type image - centos doesn't see any disk space. Then, I build a VM through the virt-manager interface - but surely I can do this within OpenNebula ? My apologies for sounding naïve- just trying to get to grips with all of this .. :) Regards, Adrian Snyman Linux Systems Administrator Tel: 011-559-4929 Cell: 082-600-1211 This email and all contents are subject to the following disclaimer: http://disclaimer.uj.ac.za ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] Not enough free memory error
Hi, I created a vm on opennebula2.2,but failed .Then i checked the vm.log, and i found the reason: Not enough free memory and enable-dom0-ballooning is False, so I cannot release any more. I need 1061888 KiB but only have 886004. I know this means the vms on my host takes too much memory and the left free memory isnot enough for the new one. So, i think it is not reasonable. If the resource is not enough ,the host should not be scheduled . Opennebula can detect host's resource ,why not add some logic to avoid this problem . Opennebula can print something to stop creation before it scp image , or add a new state for this situation. And I also want to ask masters if the new version (such as one3.0 or 3.2.1) will see the problem. Please tell me .

Re: [one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]
Hi Ruben, I am using the OpenSUSE package (installed through YaST). Just to make sure that I did the configurations right (I'm sure I didn't): At (I quote from the documentation): To be able to use the images copied by OpenNebula, change also the user and group under which the libvirtd is run to “oneadmin”, what exactly needs to be done? I am a Linux-noob (or at least, not at all an expert), so forget me this question, but how do I set the user and group under which a daemon is run? I have checked under which user is the libvirtd daemon is currently running, and indeed it is root (since I probably set it and put it in init.d as the root user). Also: (typically oneadmin) has to pertain to the libvirtd and kvm groups in order to use the daemon and be able to launch VMs. What are the libvirtd and kvm groups? And how how do I achieve the necessary configuration? I did some configuration, but I just want to make sure that I'm not missing anything (which I probably do). Ruben? Anyone?

Re: [one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]
Hello, I managed to resolve the issues regarding the monitoring, by following the instructions at [1] (sections 7.1.1.1. and 7.1.1.2), and at [2] (the section regarding PolicyKit). Now, 'onehost show 6' results in the following (see below). As you can see, although the monitoring info returned the correct result, it still contains an error message, which is stuck there from an earlier time (the timestamp of the error message is not the actual time of the monitoring, it shows the timestamp of an earlier unsuccessful monitoring try). The oned.log contains no errors. Also, I suppose because of this error message (which also appears at the bottom of the Host Template tab, with my current Host selected in Sunstone), the Monitoring Information tab shows There is no monitoring information for host 6 both at CPU and Memory info. Any idea how to work this around? Also, my initial socket problem (I copy the following from messages.log): Mar 9 10:10:57 pcls libvirtd[5603]: Starting libvirtd WARNING: no socket to connect to Mar 9 10:10:57 pcls libvirtd[5603]: ..done , still persist. This message also appears when trying to run anything related to 'virsh' on my host,, for ex: virsh -c qemu:///system list WARNING: no socket to connect to Id Name State -- , and also, it appears when running run_probes on my host (although after the warning, it returns the correct information). It is kind of bothering me, and I could find the reason of it so far. It is also making it hard to trace the fact that besides this warning message, no errors messages are issued nowhere, and I couldn't trace it in the logs neither, so far. Any ideas what causes this socket warning? Please help.

Re: [one-users] Monitoring issue right after host creation [No Monitoring Information | OpenNebula 3.2.0]
Hello, your monitoring looks fine. To get the monitoring information plots in sunstone you need to start the oneacctd daemon: http://opennebula.org/documentation:rel3.2:sunstone#monitoring_and_plots About your libvirtd warning, it think it's not critical. In my box I have the same warning but i was able to launch VMs with KVM.
