Re: [one-users] OpenNebula 3.0b2 after onevm saveas VM gone
Hi, I just wanted to add to Fabian's reply that in OpenNebula 3.0 the VM instance is lost (well, not really lost, it just happens to end its life cycle), but the template can be instantiated as many times as you need. You can also edit the template to change the image id, using 'onetemplate update id'. Since you are updating your OS image, you may want to make it persistent instead of saving another copy.

As far as I understand from documentation this is not a problem but the contents of the image are only created after the VM is shutdown gracefully (using onevm shutdown). So I did just that. The problem. The Debian VM is gone, it is not listed anymore. onevm returns empty list. The Debian VM was the only one active. Is this normal behavior if you save the only disk the VM has? This is normal behavior, see the Virtual Machine Life-cycle at [1]. The only workaround I know is to recreate the VM with 'onevm create template'. This will give an new VID for the VM. If you want to boot it with the just freshly saved image, you need to adjust your template so it will use the newly created image. [1] http://www.opennebula.org/**documentation:rel2.2:vm_guidehttp://www.opennebula.org/documentation:rel2.2:vm_guide As far as I have understood, if you want to have an VM which should run (or exists) forever do not use 'onevm shutdown vm_id' at any time, or you need to recreate the VM. Only use 'onevm stop vm_id' and 'onevm resume vm_id', which will just pause the VM (no processes are stopped inside the VM). Reboot or shutdown of the OS in the VM is possible. With using shutdown inside the VM, I had to recover (eg. boot again) the VM with waiting until 'onevm list' (or 'onevm top') shows the state as unkn and then use 'onevm restart vm_id' to boot the VM again. Hope this helps. bye Fabian __**_ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/**listinfo.cgi/users-opennebula.**orghttp://lists.opennebula.org/listinfo.cgi/users-opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] Binding VMs to clusters, maybe on a per user policy
Hello gentlemen!
I know that OpenNebula has REQUIREMENTS that can bind a VM to a
certain cluster.
But I have this problem. We will allow users to create VMs using an
OCCI+OVF implementation Engineering is writing for the Venus-C
project. At first I thought that adding the requirement on the fly
would have done the work since I needed to redirect the all the VMs
created with OCCI+OVF to a single cluster, but this could be a bad
choice for general usage, so I started wondering if there were already
hooks to get the scheduler choose the right cluster for a certain
user ? Or should I use Haizea ?

[one-users] Error monitoring host
Hi, I know the problem I am going to report has already been discussed, but what I have read from previous discussions has not helped. My Opennebula front-end has problems to monitor one of my hosts. I get the following log messages: Wed Sep 21 17:03:44 2011 [InM][I]: Command execution fail: 'if [ -x /var/tmp/one/im/run_probes ]; then /var/tmp/one/im/run_probes kvm joker; else $ Wed Sep 21 17:03:44 2011 [InM][I]: STDERR follows.

The first thing that I have noticed is that run_probes is not in /var/tmp/one/im/, but I have it in /srv/cloud/one/lib/remotes/im/. Can that be the source of the problem? If I executed from my front end machine the following command as root, everything seems to work ok: /srv/cloud/one/lib/remotes/im/run_probes kvm joker However, if i execute it as oneadmin, i get the following error: Connecting to uri: qemu:///system error: unable to connect to '/var/run/libvirt/libvirt-sock': Permission denied error: failed to connect to the hypervisor Error executing kvm.rb ARCH=x86_64 MODELNAME=Intel(R) Xeon(R) CPU E5540 @ 2.53GHz I have checked, and oneadmin is member of the cloud group in joker, I have specified unix_sock_group = cloud in /etc/libvirt/libvirtd.conf and libvirt-sock seems to have the right permissions: srwxrwx--- 1 root cloud 0 2011-09-21 17:02 /var/run/libvirt/libvirt-sock So i do not know why I get the permission denied message. However, if I run virsh -c qemu+ssh://oneadmin@joker/system, I manage to connect to virsh, w/o entering a password. So i do not really know what the problem is, and hope you can help me. The funny thing is that it used to work perfectly, but it stopped working suddenly, without me changing anything (or at least I think so).

Re: [one-users] Error monitoring host
Hi Humberto, Just a guess. What the output of the command 'grep nodeinfo_text $ONE_LOCATION/lib/remotes/im/kvm.d/kvm.rb|grep virsh' on front-end node? I have nodeinfo_text = `virsh -c qemu:///system nodeinfo` But it looks like you should change it to virsh -c qemu+ssh:///system HTH, Nikolay. Humberto N. Castejon Martinez wrote on 21/09/11 19:21: Hi, I know the problem I am going to report has already been discussed, but what I have read from previous discussions has not helped. My Opennebula front-end has problems to monitor one of my hosts. I get the following log messages: Wed Sep 21 17:03:44 2011 [InM][I]: Command execution fail: 'if [ -x /var/tmp/one/im/run_probes ]; then /var/tmp/one/im/run_probes kvm joker; else $ Wed Sep 21 17:03:44 2011 [InM][I]: STDERR follows.

The first thing that I have noticed is that run_probes is not in /var/tmp/one/im/, but I have it in /srv/cloud/one/lib/remotes/im/. Can that be the source of the problem? If I executed from my front end machine the following command as root, everything seems to work ok: /srv/cloud/one/lib/remotes/im/run_probes kvm joker However, if i execute it as oneadmin, i get the following error: Connecting to uri: qemu:///system error: unable to connect to '/var/run/libvirt/libvirt-sock': Permission denied error: failed to connect to the hypervisor Error executing kvm.rb ARCH=x86_64 MODELNAME=Intel(R) Xeon(R) CPU E5540 @ 2.53GHz I have checked, and oneadmin is member of the cloud group in joker, I have specified unix_sock_group = cloud in /etc/libvirt/libvirtd.conf and libvirt-sock seems to have the right permissions: srwxrwx--- 1 root cloud 0 2011-09-21 17:02 /var/run/libvirt/libvirt-sock So i do not know why I get the permission denied message. However, if I run virsh -c qemu+ssh://oneadmin@joker/system, I manage to connect to virsh, w/o entering a password. So i do not really know what the problem is, and hope you can help me. The funny thing is that it used to work perfectly, but it stopped working suddenly, without me changing anything (or at least I think so).

Does 'onevm list' still show your VM which you just did shutdown? Because: Here is the output of oneimage show 32 ID : 32 NAME : alliswell TYPE : OS REGISTER TIME : 09/13 16:12:13 PUBLIC : No PERSISTENT : No SOURCE : /srv/cloud/one/var/images/def71f75ceab7d2fa444927b8e1588633c547422 STATE : rdy RUNNING_VMS: 1 There is still is a VM running which does use this image. Also you need to change some other settings, like maybe PERSISTENT (see help of oneimage) to Yes. IMAGE TEMPLATE DEV_PREFIX=hd NAME=alliswell TYPE=OS Depending on your settings during the installation of this disk, you probably want to change DEV_PREFIX to sd (for SCSI disk) with the 'oneimage' command. This is a known bug of the saveas command in 2.2.1. Since I'm able to save/ clone the VM , I guess there is no problem with user rights access to the nfs shared folder . But your error says: cp: cannot stat `/srv/cloud/one/var/images/def71f75ceab7d2fa444927b8e1588633c547422': No such file or directory When the VM did not shutdown properly (from OpenNeubla's point of view), then the image is not copied/moved to the images folder. The entry with 'oneimage list' and 'oneimage show image_id' is there, but the file in you images folder is not yet. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] onevm save method error
Hello Bala On 20.09.11 13:44, bala suru wrote: I need to save modified VMs as new one - here can I do normal copy and save the VM which is running and modified ..? You could first register a persistent image, then create a persistent VM, run it and do your installation/updates. Then run 'onevm shutdown vm_id'. Now you could create an other VM using the same registered image (makes probably not much sense), or copy the image away from your image folder, create a new template and register the copied image with a new name. Then create a new persistent VM which will use the new image. Can I deploy the new VM using the save Image ..? Probably as described above. But to clone a running image, the 'onevm saveas vm_id disk_id image_name' command and then 'onevm shutdown vm_id' (as in your link described the VM and the OS running in the VM needs to support ACPI) are probably easier to use and you do not need to manually copy around the image. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] onevm saveas error
Hello Bala On 21.09.11 07:37, bala suru wrote: I have used a some simple way to copy the image running Vm image(insted of onevm saveas) , 1. I did some modification over the running image(creating some files) 2. issued onevm suspend 3. copied var/images/uuid file of the running image 4. Registered the above copied image as a new image 5 . launched the new VM using above image But I could not see any modified files on this VM ,,? This could have two reasons. First, is this a persistent image? Second, did the VM have enough time to write back the changes to the image? But I guess the second one is difficult to find out, as the OS in the VM and probably also the VM layer do some caching in memory and the write back to the image is delayed for a longer time. Are the steps which I followed are correct ..? I do not think, that this is really supported from ONE. You are taking an image away from a running VM (even in the state suspended), which could have an not cleanly saved state of the file system in the image. It is much better to use an OS and VM which does support ACPI and then use the 'onevm saveas vm_id disk_id image_name' and 'onevm shutdown vm_id' commands. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
Re: [one-users] changing virtual network online
Hello Samuel On 21.09.11 14:45, samuel wrote: I've just wondering whether is it possible to change the virtual network that a virtual machine is attached once it has been working (deploy-run). With 'onevnet' you can change some settings of an network, eg. leases / mac addresses. But as I understand, you try to modify stuff which belongs to the VM itself. I've tried to modify the deployment.0 file but it did not affect the new restarted machine. Might be a problem with the underlying MySQL database that has to be also changed? As far as I know, it is currently not supported to change an already running VM. Use Case: *create a new virtual machine and just forgot to attach a virtual network *modify a virtual network (in case of VLAN change) *attach a new interface to a running machine. The steps which could work, and will give minimum downtime are probably the following: - update your VM template with the new / changed network / NIC - run 'onevm shutdown vm_id' (with a registered persistent disk image, all the modifications in the VM are preserved). - wait until shutdown has completed, check with 'onevm list' or better 'onevm top' - run 'onevm create template' and the same VM will boot up (now with a different VM ID, but with the same registered persistent disk image) bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

I guess the ssh login from the front end to the cluster node with the user oneadmin does not work. Try manually from the front end to use 'ssh -v oneadmin@joker' (the -v gives some verbose output, if you increase eg. with -vvv, it will give even more). It guess on the cluster node the file ~oneadmin/.ssh/id_dsa.pub is missing (or not readable for oneadmin). Check also the sshd log file on the cluster node. bye Fabian ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org
