Adding an "URGENT" to the subject won't help anyone. Please be more patent. I'm mostly ignoring such mails... -- Thanks, //richard ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

[one-users] onevm auth error

Okay, so I changed the password for the oneadmin user via the sunstone interface - now the commandline is suddenly broken :( The one_auth file needs to have an encrypted string for the password - plain text does not work. So how do I generate an encrypted password ? Regards, Adrian Snyman Li

[one-users] migrate virtual machine

Hi all, I have a problem when I try to migrate a virtual machine using Opennebula 2.1 with NFS and KVM on Ubuntu 10.10. I performed as the path " http://marianmi.comp.nus.edu.sg/2010/08/opennebula-installation-and-configuration-guide.php"; but my system only consists of 2 computers : one installs O

[one-users] [openSUSE + OpenNebula 3.2.0 + KVM. How to obtain an .img file?]

Hello everyone, Regarding my last issue here, the problem with the VNC connection initialization through Sunstone was indeed the presence of the line ['TIGHT_PNG',        -260 ], in rfb.js. Uncommenting it solved the problem; thank you Carlo and Hector for you prompt feedbacks. So, at my curre

[one-users] [openSUSE 12.1 + OpenNebula 3.2.0 + KVM. Template to be used?]

Okay, I just bumped into Suse Studio right after sending my previous mail; I must have been a moron for not discovering it before. As I understood, it provides me with a raw image file (with .raw extension), so my only question related to this matter is: can this .raw file be used in the exact s

[one-users] Shared File System HA

I am debating the differences between Shared and Non-shared file systems for an OpenNebula deployment. One concern with the shared file system is High Availability. I am setting up the OpenNebula front-end with connectivity to a storage device. To avoid the event of a storage device failure (

Re: [one-users] onevm auth error

hi, I tried quickly and this problem doesnt happen to me. I changed oneadmin password via sunstone, then updated one_auth with the plain text password and things work fine. Have you changed the oneadmin authentication driver perhaps to something other than 'core'? What version of ONE are

Re: [one-users] Shared File System HA

In case we are going to deploy OpenNebula we will use GPFS as our clustered FS ... Since it does not answer your question: In case NFS is used you must make sure that: • The NFS server exports the FS with the “sync” option. Otherwise data corruption could/will during server crash. • The NFS c

Re: [one-users] create vm error : No space left on device

Hi, What I meant it that an external script could monitor each physical host, get the free storage and, if it is lower that a threshold (e.g. 10 or 20 GB) execute a 'onehost disable hostname'. This way you will prevent the scheduler from sending VMs to that host from that moment onwards. Regards

Re: [one-users] migrate virtual machine

You will be able to migrate only if you have more than 1 cluster nodes (where KVM is installed) On Wed, Mar 14, 2012 at 5:02 AM, Tung Duong wrote: > Hi all, > I have a problem when I try to migrate a virtual machine using Opennebula > 2.1 with NFS and KVM on Ubuntu 10.10. I performed as the path

Re: [one-users] Shared File System HA

If you are looking at HA at storage level, it would be better you have Heartbeat/Failover on the NFS resource than failing over to secondary front-end server. Anyway your NFS is mounted on the compute nodes and if one storage goes down, heartbeat will failover to another storage. Your frontend does

Re: [one-users] Distributed storage, local copy

Hi Marshall, It all depends on how you will use you cloud. For example in the last setup I worked on we tried distributed storage. But we just hit the IOPS maximum of our storage (see IOPS on wikipedia for more info). It is due to the fact that we have a lot of VM and no SATA / SAS / iSCSI with o

Re: [one-users] Shared File System HA

In my design I'm looking at having the shared storage attached to the front-end server and provide full redundancy for both the front-end and the image repository. This would then be shared to each compute node via NFS. StorageArray1 ---DAS--->FrontEnd1---10gb Eth>BladeChassis1 | | DRDB/Hea

Re: [one-users] Shared File System HA

It is plain nfsclient to nfsserver behavior. Hypervisor is just acting as NFS client. The OS of the VM is caching the writes in memory and periodically writing to Hard disk. During the failover the NFS client will continue to try to write but will fail if it cannot connect to the NFS server before

Re: [one-users] URGENT: Host has capability to start and stop VM???

VM opens a VNC port on the host. You can ssh to the host and portforward to the VNC port and access the console. ssh user@frontend -L5906:host: Then on your local machine you can access the console via vncviewer on port 5906. You can obtain vncport of the VM from the deployment.0 file On Wed, Mar

Re: [one-users] Shared File System HA

Thanks for the update and information. What about the possibility of using a distributed file system (say MooseFS and ucarp for HA) and designating each front-end/controller host as a chunk server? In that setup, there would only be 2 chunk servers, each with a large array attached. Would the

Re: [one-users] onevm auth error

Hi Hector, thanks for getting back to me. Not too sure - but the problem is reproducible each time my side. I wonder whether it's my sunstone installation ? If I reset the password via the commandline, then set the on_auth file to plain text - it works no problem. If I reset via the sunstone in
