[Users] actual disk size of vm via api
by Sven Kieske 12 Feb '14

12 Feb '14

Hi, I got a question regarding the reported actual disk size of a vm. you can obtain this value fine via api: https://your_engine/api/vms/{id}/disks/ however, if the vm is cloned from a template this disk size does not seem to show the actual size of the whole disk but instead the difference from the actual template size. is this a bug or a feature? I would like to obtain the "real" size. e.g. I have a template with 50GB (thin provisioned) the actual size of this template is 1,5 GB I clone a vm from this template, the actual size which gets reported via api is about 8 MB (stuff that changes from the template). So I can not obtain the complete used size of the vm. This was tested under ovirt 3.3.2 -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

First you will need to create a VM manually, install the cloud-init package, and then make a template from this VM. Once you have this template you can use something like the following to create a VM from that template, and start it so that cloud-init will assign the password you want: // Generate the random password, using whatever mechanism you // prefer: String password = ...; // You need to know the name of the template, the cluster and // the VM you are going to create: String templateName = "mytemplate"; String clusterName = "mycluster"; String vmName = "myvm"; // Prepare the data to create the VM from the template: Template templateData = new Template(); templateData.setName(templateName); Cluster clusterData = new Cluster(); clusterData.setName(clusterName); VM vmDataForCreate = new VM(); vmDataForCreate.setName(vmName); vmDataForCreate.setCluster(clusterData); vmDataForCreate.setTemplate(templateData); // Send the request to create the VM to the server: api.getVMs().add(vmDataForCreate); // White till the VM is down (it will be locked for a while): for (;;) { String state = api.getVMs().get(vmName).getStatus().getState(); if ("down".equals(state)) { break; } Thread.sleep(1000); } // Populate parameters for the action to start the VM with cloud-init: User userData = new User(); userData.setUserName("root"); userData.setPassword(password); Users usersData = new Users(); usersData.getUsers().add(userData); CloudInit cloudData = new CloudInit(); cloudData.setUsers(usersData); Initialization initData = new Initialization(); initData.setCloudInit(cloudData); VM vmDataForStart = new VM(); vmDataForStart.setInitialization(initData); Action actionData = new Action(); actionData.setVm(vmDataForStart); // Send the request to start the VM to the server: api.getVMs().get(vmName).start(actionData); > > > > > On Tue, Feb 11, 2014 at 9:01 PM, Juan Hernandez <jhernand(a)redhat.com > <mailto:jhernand@redhat.com>> wrote: > > On 02/11/2014 04:16 PM, Itamar Heim wrote: > > On 02/11/2014 04:55 PM, Tejesh M wrote: > >> Thanks for your fast response. > >> > >> But intelli sense is not listing vm.*start *function > >> > > This is because you are using the VM class from the > org.ovirt.engine.sdk.entities package, instead of from the > org.ovirt.engine.sdk.decorators package. > > The entities package contains classes that plain containers for the data > that is sent to and received from the server. > > The decorators package contains classes that extend those plain > containers adding functionality like the action methods. > > >> I'm using rhevm-sdk-java-1.0.0.29-1.jar > >> > >> _*code:*_ > >> > >> import org.ovirt.engine.sdk.Api; > >> import org.ovirt.engine.sdk.common.*; > >> import org.ovirt.engine.sdk.decorators.VMDisk; > >> import org.ovirt.engine.sdk.entities.*; > >> import org.apache.commons.beanutils.*; > >> > >> > >> public class rhvm { > >> static Api api; > >> public static void callAPI() > >> { > >> try{ > >> > >> api = new Api("https://rhevm:443/api", "admin@internal", > >> "password"); > >> > >> > >> org.ovirt.engine.sdk.entities.VM vm = > >> api.getVMs().get("testVM3"); //get VM > > If you want to be able to use the "start" method you will need something > like this: > > org.ovirt.engine.sdk.decorators.VM vm = api.getVMs().get("testVM3"); > > Then your IDE will show you the additional methods in the decorator, > including the "start" method. > > >> vm.setDescription("java_sdk"); > >> > >> System.out.print("VM ID:" + vm.getStatus().getState()); > >> System.out.print("VM ID:" + vm.getId()); > >> > >> > >> } > >> catch(Exception e) > >> { > >> System.out.print(e); > >> } > >> finally { > >> api.shutdown(); > >> } > >> } > >> public static void main(String a[]) throws Exception > >> { > >> //rhvm obj = new rhvm(); > >> callAPI(); > >> System.out.println("\ncompleted"); > >> } > >> } > >> > >> > >> > >> > >> On Tue, Feb 11, 2014 at 8:08 PM, Ewoud Kohl van Wijngaarden > >> <ewoud+rhevm-api(a)kohlvanwijngaarden.nl > <mailto:ewoud%2Brhevm-api@kohlvanwijngaarden.nl> > >> <mailto:ewoud+rhevm-api@kohlvanwijngaarden.nl > <mailto:ewoud%2Brhevm-api@kohlvanwijngaarden.nl>>> wrote: > >> > >> On Tue, Feb 11, 2014 at 08:00:57PM +0530, Tejesh M wrote: > >> > Can anyone share sample on how to Start & Stop VM using > Java SDK?

Re: [Users] [Freeipa-users] RHEL 7 beta trust - slow domain user authentication to Linux hosts
by Steve Dainard 12 Feb '14

12 Feb '14

+Ovirt users mailing list - might find this interesting. Quick background: IPA server with cross-forest trust to Windows domain. Authenticating to Linux clients with domain kerberos credentials. I'm hosting CentOS 6.5 as an ovirt guest, and have narrowed this ipa client slow login issue down to a backend storage cause. If I enable async writes to NFS the CentOS guest performs as my workstations virtualbox guests (Ubuntu 13.10/Fedora 20) do on login (quick logins). The client we are investigating is a CentOS 6.5 machine. I've also done the same test on a RHEL 6.5 machine with the same results. I've increased the logging level, log attached. I don't see the DC in the logs anywhere. I guess from an IPA perspective there is not much to be done, but I wanted to make sure this thread came to some conclusion for future readers. I suppose the only thing to question, is why ipa authentication would have any reliance on disk read/write speed to this extent? Perhaps we are caching something to disk that should be cached in memory? *Steve Dainard * IT Infrastructure Manager Miovision <http://miovision.com/> | *Rethink Traffic* *Blog <http://miovision.com/blog> | **LinkedIn <https://www.linkedin.com/company/miovision-technologies> | Twitter <https://twitter.com/miovision> | Facebook <https://www.facebook.com/miovision>* ------------------------------ Miovision Technologies Inc. | 148 Manitou Drive, Suite 101, Kitchener, ON, Canada | N2C 1L3 This e-mail may contain information that is privileged or confidential.

[Users] Memory usage
by Koen Vanoppen 12 Feb '14

12 Feb '14

Dear all, When we monitor one of our machines, we noticed that there was one vm that was constantly giving a error of memory usage. But when we took a look at it, there is actually nothing wrong with it. Now we looked furhter then that. We looked at the API of the machine and noticed something very strange: <statistic href="/api/vms/3b9aa245-75ff-42e8-b921-1c9ce61826bf/statistics/b7499508-c1c3-32f0-8174-c1783e57bb08" id="b7499508-c1c3-32f0-8174-c1783e57bb08"><name>memory.used</name><description>Memory used (agent)</description><values type="INTEGER"><value><datum>*-944892806* </datum></value></values><type>GAUGE</type><unit>BYTES</unit> It's a negative... What could be the problem? Kind regards, koen

[Users] oVirt 3.4 test day - results
by Alexander Wels 12 Feb '14

12 Feb '14

Hi, I tested the following items during the test day and here are my results: 1. "reboot VM" functionality The related feature page is: http://www.ovirt.org/Features/Guest_Reboot The feature page mentions a policy selection checkbox which I was unable to find in the web admin UI at all. I checked the patches that implement the feature and did not see the check box implementation. The patches did show me that all I need to use the feature was to install the guest agent on the guest. So for my test I installed a fedora guest, and I installed the guest agent on the guest. After about a minute after starting the guest, the reboot button was enabled and pressing it started the reboot sequence on the guest. I had a console open on the guest and it informed me that the admin had started the reboot process and the guest would be rebooted in a minute. I did not find a way to change the time it took for the reboot to happen. I did the same test with the REST api, with the same result. The reboot was scheduled for a minute after I issued the command. I did not find a way to change the time with the REST api either. I am guessing that is a future feature. 2. Fix Control-Alt-Delete functionality in console options I had trouble getting spice to work in my test setup, but no issues with VNC. So I tested VNC. I checked the VM console options to make sure that 'Map ctrl-alt-del shortcut to ctrl+alt+end' was checked. Then I connected to a running VM with VNC. I pressed ctrl-+alt+end expected it to issue a ctrl-alt-del to the guest. Nothing happened. I pressed ctrl-alt-del and it properly issued ctrl-alt-del to the guest. I made sure there was no issue with my client by using the menu to issue a ctrl-alt-del to the guest which also resulted in the proper action on the guest. I opened a bug for this: /https://bugzilla.redhat.com/show_bug.cgi?id=1057763/[1] I did this test on my Fedora machine, and the description mentions that certain OSes capture the ctrl-alt-del before sending it to the guest, Fedora is not one of those OSes, so maybe my test was not valid? 3. Show name of the template in General tab for a VM if the VM is deployed from template via clone allocation. This is a very straight forward test. I created a template from a VM. I named the template. Then created a VM from that template using clone allocation. I verified that the name of the template is now properly shown in the VM general sub tab. Works as expected. Overall I had issues getting engine installed due to the shmmax issue reported in other threads, and then I had a really hard time adding new hosts from a blank fedora minimum install. I was successful one out of three attempts, which I feel was probably an yum repository issue as I was getting conflicting python-cpopen issues causing VDSM to not start. Thanks, Alexander -------- [1] https://bugzilla.redhat.com/show_bug.cgi?id=1057763

[Users] [ovirt-test-day-2] - testing neutron integration - remove external networks
by Omer Frenkel 12 Feb '14

12 Feb '14

Hi, I tested $subject, I have to say i don't know much about networks / neutron, so maybe some of the issues i encountered are just my fault.. i used pre-configured neutron server (thanks Mike!) and the beta2 for ovirt-engine, i used the wiki to configure it: http://www.ovirt.org/Overlay_Networks_with_Neutron_Integration these are the issues i've seen: 1. add provider is hidden, since 'system' node in the tree is collapsed by default, i couldn't find it, the way to add provider should at least be documented in the neutron integration wiki, i had to ask around to find it.. 2. add provider dialog: wrong tab indexing - after entering name, i clicked 'tab' to enter description, but the focus moved to the 'cancel' button [bug 1064240] this is pretty minor, but i think its basic usage issue, and probably easy fix. 3. selecting 'Subnet' sub-tab of the imported external network doest show anything, and creates an error in the engine log [bug 1064231] Other than that, i was able to create and remove the external network with no issues, we might need a better (maybe step-by-step?) documentation on configuring this, as it was not trivial (there are manual steps need to be done on the hosts..) or, even better, automating everything needed on the host side into host-deploy. Thanks, Omer.
