[one-users] How do i know the cluster's datastore's capacity?
Dear all: How do i get the whole capacity for a cluster's datastores, I have two hosts in a cluster, every host has 100GB space for /var/lib/datastore. In sunstone i find the capacity of cluster only display the capacity of host where the sunstone deployed. Best Wishes!

Re: [one-users] How do i know the cluster's datastore's capacity?
That's because you are not using a shared folder for all hosts. A better way to do it is to make the /var/lib/datastore/1/ folder on the sunstone as a NFS folder and then mount it all other hosts on the same location /var/lib/datastore/1/. This will enable you to do live migrations and very fast deployment of vms. --- Thanks, Kenneth Apollo Global Corp.

Re: [one-users] how could i move the exist vms to nebula?
Mainly depends on the amount of VMs, but the simplest way is to import as an Image, providing the VM disk filepath, and then build an adequate template for it. Don't forget to make the image persistent if you want to preserve changes. -- André Monteiro On Nov 26, 2013 8:01 AM, hansz hanshizhun...@126.com wrote: hi man, i have a question, how could i move the exist vms on esxi5.1 to nebula control them？ can i ? how ? thinks. ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org ___ Users mailing list Users@lists.opennebula.org http://lists.opennebula.org/listinfo.cgi/users-opennebula.org

Re: [one-users] How do i know the cluster's datastore's capacity?
You can of course. But it is up to you to monitor. And using storage on different hosts will cause the VMs to be copied via scp which is pretty slow. Another way to have a large storage is to remove other drives on the nodes (or use small drives in them) and then plug big capacity drives on the main NFS node. I mean put everything on the host A and let other have a small hard drive just enough for the OS itself. --- Thanks, Kenneth Apollo Global Corp. On 11/26/2013 04:48 PM, 曹海峰 wrote: Thanks for replay!

Re: [one-users] updating TEMPLATE from hooks with onevm update
Hi, When the VM is created, the template contents are parsed and stored in VM/TEMPLATE. All the extra unknown attributes are stored in VM/USER_TEMPLATE. You can see this with the onevm show -x command. The onevm update action only allows to edit the USER_TEMPLATE attributes, and as you described, the create hook is triggered after the VM has been correctly created. I don't see any easy way to make your work flow fit into OpenNebula. Could you elaborate a bit more on your use case? I'm assuming you want those two variables to end in the context section of the VM. In that case the preferred way to do so would be to have a VM Template for each Image, and in there set the needed variables.

Also, I validated that when I first installed ONE 4.2, the log messages were there, but now are not. I went back to my logs from a few weeks ago and see all the messages I would expect.

You can also do some extra sanitization / filtering and not allow the VM to be deployed if contains some missing attributes, etc. by not calling the onevm release at the end. This works very well for us. In fact, we do some heavy stuff in the hooks, such as attaching additional IP addresses, attaching or detaching disks, etc. dynamically according to external sources, such as the OpenNebula user template (but also external databases, CRM, etc.) My hook job is ok regarding vm user_template update, I tried with and without VM_SUBMIT_ON_HOLD (thanks for the hint), but I have the same issue, my user_template variables are not set in the context.sh file. What I expect is to get my USER_TEMPLATE in the context.sh mounted in my VM. A basic use case is to generate a unique password for a web application running in the VM. I'd like to generate the passsword with a hook and send the password to the user by mail (until here, this is fine). The generated password is also in the VM context/template so that it appears in the context.sh of the VM. At startup, a specific init script read the VM contextualization and init the web application with the password provided. The above example could be managed directly in the VM, without specific contextualization, but there are cases where some variables could be user dependent, so those variables would need to be set dynamically on opennebula server side. Perhaps that's the real problem here... I'm not very familiar with context.sh script. Is the entire VM template available (including the USER_TEMPLATE) or only the CONTEXT section? user_template is not set by itelf in the vm context file, only the context. But in my context, I add variables that refer to USER_TEMPLATE (but it is right that there are not set in first place, only after hooks). So it seems that we can refer to USER_TEMPLATE var, but only if there are predefined, not added in a hook (template not regenerated/calculated). the best would be to have user_template vars added to the context.sh file in addition to the one in the vm template, AFTER the hooks.

Re: [one-users] datastore log info missing from oned.log in v4.2
Then it seems that this has changed since the 3.8.x series. I use log_debug script function to log various messages in my drivers. I have my log level set to DEBUG in conf file. I used to see those messages, as I would expect, unless I changed the log level to something above DEBUG. The messages were logged regardless of the outcome of the script. It seems that if that is no longer the case, then the log facility can't be used for anything other than error conditions and having DEBUG, INFO, etc. is not very useful anymore. Maybe I'm missing the point of the feature, but it definitely did not work this way before and was something I relied on for certain things. I'm now overriding the log_debug function locally in my script and writing the output to my own log file. That is not as nice because now the log entries are not intertwined with other events which are happening in the oned.log file. IMO, any message should be written to the file based on the configured log level. Let me know your thoughts. Thanks for the reply, gary - Original Message - From: Javier Fontan jfon...@opennebula.org STDERR is only logged when the action is not successful, maybe that is your problem.

My original task was to get my custom drivers working with ONE 4.2. I was able to do so. It was related to a bug fix where the SRC DST arguments to pre/postmigrate were swapped. I simply had to swap them back. The irony in it is that I was the one that suggested the pre/postmigrate feature request and reported that bug. ;) So, I'm happily able to live migrate again. Oddly though, I am unable to get any log messages to show up in oned.log file. I'm guessing some of the common script libraries have gotten reorganized, so I need to dig in a bit more on this issue.

I used to see any logged messages up to the level of the log mode in the oned.log file. It seems like 'debug' mode should log regardless of the exit code of the script. Even if I changed the logs from log_debug to log_error, still no output. I'll try forcing exit 1 to see if that causes the logs to show up. Also, I validated that when I first installed ONE 4.2, the log messages were there, but now are not. I went back to my logs from a few weeks ago and see all the messages I would expect. I did not have time to work on this, so the server sat for a few weeks. Now I'm back to working on it and not seeing the messages. Very odd. Will let you know if setting exit 1 helps.
