[one-users] move VM to different host
HI, Is there a way to move a VM from one host to an other when migrate/live migrate fails. We are using ceph as backend and have ssh systemstore. A process like 1 poweroff VM 2 Move the configs 3 -- I guess that we should do some manual db changes -- 4 poweron machine on new host Any comments would be great.

Re: [one-users] move VM to different host
If you are using 4.10, we do support migrations when a VM is in unknown (i.e. hypervisor is down) provided there is a shared storage. Next release (4.12) will include the ability to migrate in poweroff. Meanwhile a work around, (there are two actually fake a hypervisor failure to get the VM in unknown and use the previous feature or fake a migration failure). I've not tested this myself so watch out: 1.- Update the kvm migrate script by adding at the very beginning something like: sleep 600 return We want to get the VM in MIGRATE state for a while 2.- Manually move the VM: Go to the hypervisor, and shut it down (i.e. virsh...); move the config files (those in ssh system datastore); got to the other hypervisor and manually create the VM. 3.- use onevm recover vmid success, the VM should become running in the new host. (The sleep'ed migrate operation should be ignored as the VM would be RUNNING) 4.- Undo the changes in the migrate script.

[one-users] opennebula 4.8 can't detect the capacity
Hi All, After search some articles and mailing list and try my best, my ceph datastore can't monitor the capacity. 1) How can opennebula detect the size of ceph? - Opennebula is a ceph-mon? If yes, how can oneadmin user can run the rados command to show the capacity, only root can do that? It must be sudo rados, right? - The opennebula accesses to ceph-mon(font-end) with password-less to run ssh ho-srv-ceph-02 rados df | grep Total If yes, i need an user oneadmin in ceph-mon and ability to run rados df without sudo, so how? only root can run rados in this case. 2) Was any step i missed ? Some description for my system: Ceph: - Deploy:ho-srv-ceph-01 - MON,OSD: ho-srv-ceph-02,ho-srv-ceph-03,ho-srv-ceph-04 - Sudo: ceph ALL = (root) NOPASSWD:ALL for all Opennebula: For testing ceph datastore only, i use one standalone server with oneadmin user Opennebula: cloudlab-02 Prepare for ceph: - password-less from ceph-deploy - Sudo:ceph ALL = (root) NOPASSWD:ALL for all - in ceph-deploy [root@ho-srv-ceph-01 ~]#ceph-deploy install cloudlab-02 I use use ceph to access from ceph to opennebula and user oneadmin to access from opennebula to ceph Following the official document: - in ceph monitor [root@ho-srv-ceph-02 ~]# ceph osd pool create one 64 - in opennebula front-end [oneadmin@cloudlab-02 ~]$ cat ceph.one NAME = ceph DS_MAD= ceph TM_MAD= ceph DISK_TYPE = RBD POOL_NAME = one BRIDGE_LIST = ho-srv-ceph-02 [oneadmin@cloudlab-02 ~]$ vi ceph.one [oneadmin@cloudlab-02 ~]$ onedatastore create ceph ceph1.one ceph2.one ceph.one [oneadmin@cloudlab-02 ~]$ onedatastore create ceph.one ID: 105 Thank you.

Re: [one-users] No option to remove quota from sunstone (4.10)
Hi Carlos, Yes, I know the default quota is set to unlimited, However the issue that I am facing is different. Lets say I have a user - abc and I have 2 networks with ID 0 and 1 in Virtual Networks and I have assigned quota of both the networks to the user. Screenshot : [image: Inline image 1] Quota assigned to the user, Check under network section of quota. [image: Inline image 2] Now I delete one of the virtual network with ID 1 and after that if you check the quota it still shows the Network ID 1 and it does not have the option to remove it from there as it is not required [image: Inline image 3] [image: Inline image 5] So the quota section have only option to add new quota but not to remove that particular ID - (in this case it is ID -1) and it lies there even after the virtual network does not exist. I think there should be a small button to remove that orphan entry from the section and also there should be a validation if a particular resource does not exist and this applies to Image, network and datastore section in quota. Let me know about your view on this approach.

[one-users] Fwd: OpenVswitch and host crash
Hi Daniel, I feel it's best not to trigger automatic recovery actions when a host fails. The complexity of developing heuristics to deal with all the technologies OpenNebula leverages would be enormous. And the commands you had to run in this particular case might change in future Open vSwitch releases... That said, I would personally do this outside of OpenNebula, in an rc.local sort of place. But if you really want to do this within OpenNebula you can always create a probe that is executed with all the other IM actions, that checks if Open vSwitch is up and healthy, and otherwise fixes it. cheers, Jaime On Mon, Oct 13, 2014 at 10:02 AM, Daniel Dehennin daniel.dehen...@baby-gnu.org wrote: Hello, We had a power failure on a test ONE 4.8, the frontend and the two hosts crashed.

The /var/lib/one contents are needed in the front-end but not by the nodes. Just the system datastore directory. If the VM tries to access a disk from a device that is not mounted or the NAS server is down you'll be in trouble. However, note that context ISO is only accessed during the boot state and the main disks of the VM are in the ceph pool, so you'll probably be fine (but if not tested it) Cheers On Mon Nov 10 2014 at 3:38:14 AM Huynh Dac Nguyen ndhu...@spsvietnam.vn wrote: Dear Ruben, Thank you for replying So what happens if the front-end opennebula is down the /var/lib/one isn't mounted,only System Datastore is mounted, then the VM can't work, right?

If you need live-migration the easiest way is to have a shared filesystem for the System Datastore. You don't need to export the whole /var/lib/one, just the datastore directory, though.

You have to configure ceph in such a way that oneadmin can run the rados command without sudo.

It can't contact Ceph as yet, is getting connection refused but we think that is an authentication issue. http://ceph.com/packages/qemu-kvm/redhat/x86_64/ is where these packages for 6.2 live. Hopefully this all gets easier pretty soon now that RedHat has bought Ceph and all the right packages will be in RHEL7.

Re: [one-users] Stopping a VM erases it
Hello Jaime, qemu.conf is ok : # grep -vE '^($|#)' /etc/libvirt/qemu.conf user = oneadmin group = oneadmin dynamic_ownership = 0 I found that |: - user qemu belongs to group 'kvm', but oneadmin doesn't - I have no libvirtd group - /etc/libvirt/libvirtd.conf had listen_tcp=1 commented - ||/etc/sysconfig/libvirtd had ||LIBVIRTD_ARGS=--listen commented Can I restart libvirt without affecting running VMs?

Re: [one-users] Do we need to mount /var/lib/one with ceph
Hi Jaime, The cephfs looks easier than ceph datastore. - /var/lib/one - not shared, only for frontend If not shared, /var/lib/one should be synchronized between multi-frontend, right? - /var/lib/one/datastores - lives in a cephFS share avaialble to the frontend and all the nodes this location is mounted in all nodes as file system to be sure any nodes can show all data in cephfs? It's good ideas, I will do it now. But i really want to use ceph data store, could you show me the right way.? Regards, Ndhuynh Jaime Melis jme...@opennebula.org 11/19/2014 11:05 PM Hi, are you planning on using CephFS? if that's so you might find it easier to set it up like this: - /var/lib/one - not shared, only for frontend - /var/lib/one/datastores - lives in a cephFS share avaialble to the frontend and all the nodes would this suit you? cheers, Jaime On Wed, Nov 12, 2014 at 6:09 AM, Huynh Dac Nguyen ndhu...@spsvietnam.vn wrote: Dear Ruben, You mean: - /var/lib/one is mounted from NAS server just for Front-end - The datastore is mounted from Ceph for frond-end and node So Front-end servers must be mounted NAS (/var/lib/one) and Ceph (/var/lib/one/datastores/[number]), 2 mounted points. Node servers must be mounted only Ceph (/var/lib/one/datastores/[number]), 1 mounted point and the passwordless file must be updated manually Is it correct? so why don't we use ceph for both of shared location? or just /var/lib/one?

Note that you don't need to be it exported from the front-end, the nodes and the front-end itself can mount it from an different NAS server. The /var/lib/one contents are needed in the front-end but not by the nodes. Just the system datastore directory. If the VM tries to access a disk from a device that is not mounted or the NAS server is down you'll be in trouble. However, note that context ISO is only accessed during the boot state and the main disks of the VM are in the ceph pool, so you'll probably be fine (but if not tested it) Cheers On Mon Nov 10 2014 at 3:38:14 AM Huynh Dac Nguyen ndhu...@spsvietnam.vn wrote: Dear Ruben, Thank you for replying So what happens if the front-end opennebula is down the /var/lib/one isn't mounted,only System Datastore is mounted, then the VM can't work, right?

Montero rsmont...@opennebula.org 11/7/2014 4:52 PM Hi Ndhuynh Ceph storage in OpenNebula is handled as follows: 1.- Image Datastores, hold disk images repository as well as images for running VMs in a Ceph volume 2.- System Datastore holds additional VM files, checkpoints, context disks and the like. If you need live-migration the easiest way is to have a shared filesystem for the System Datastore. You don't need to export the whole /var/lib/one, just the datastore directory, though. If you do not need to live-migrate VMs you should be ok with a ssh based system datastore Cheers On Wed Nov 05 2014 at 12:09:47 PM Huynh Dac Nguyen ndhu...@spsvietnam.vn wrote: Hi All, I'm researching opennebula with ceph, i saw that most of guide focus on using ceph as datastore - block device, right? Do we need to mount ceph to /var/lib/one as file system to prevent the opennebula frontend down expectedly? My script is: 1) Make a ceph file system : one and mount to /var/lib/one in all opennebula node (front-end and node) 2) Create a ceph block device and add to opennebula as datastore Is this a right way?
