[Users] taking advantage of extra disk space on nodes
by Robert Story 13 Feb '14

13 Feb '14

--Sig_/3JPaVh0uh3olCd4JN0DHdY. Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: quoted-printable So I've got a handful of oVirt nodes now, and most of them have over 100G of unallocated disk space. I'm trying to figure out how to best take advantage of that space. I see two possibilities: storage for oVirt, or backup/archive storage. I'm currently using a single NFS server for VM/iso/export storage (oVirt 3.3.x on CentOS, if it matters) and don't need to scale to hundreds of nodes (probably 10-20, max). Is current gluster support stable enough for production? What are the pros/cons of gluster vs NFS? I like the idea of not having a single point of failure but worry about performance. The other option is to stick with my NFS server and use the extra storage for archive/backup space. Here I'm looking for reliability (i.e. losing a server won't cause data loss) over performance. Are there pros/cons to gluster vs ceph? Will either/both peacefully co-exist with an ovirt node? All suggestions welcomed. Thanks!

[Users] test day help -- console
by Greg Sheremeta 13 Feb '14

13 Feb '14

I'm having a tough time getting a VM console working via VNC. I set a VM to use VNC, and I installed virt-viewer. 1. When I try to open a .vv file with virt-viewer, I get an error "Cannot find guest domain /var/tmp/console.vv" 2. Using a VNC client to connect to the host with the password in the .vv file just immediately disconnects it -- no error message. 3. noVNC just gives me an empty popup with a gray background. Any ideas? Greg Sheremeta Red Hat, Inc. Sr. Software Engineer, RHEV Cell: 919-807-1086 gshereme(a)redhat.com

[Users] Dedicated Bonding interface for Gluster
by ml ml 13 Feb '14

13 Feb '14

Hello List, i would like to use a dedicated Bonding Interface for Gluster Replication and Migration. I was already able to add my Bonding Interfaces in my Hosts-Network Tab, however i am failing to tell Gluster to use this interface. It only offers me nodeX.local (which is my managment network). More infos are collected here: http://oi58.tinypic.com/v6qaa1.jpg Can someone tell me how to configure Gluster to use the dedicated bond interface? I already asked in the IRC Channel but nobody seems to know :-/ Thanks, Mario

Hi, I have tested iproute2: Test: ========== - Deployed Host (EL family) - put in maintenance - on host changed vdsm.conf to: [addresses] management_port = 54321 [vars] ssl = true net_configurator = iproute2 net_persistence = unified - put host up - Added the network (net25) -> Networks -> New -> Name: net25 [X] Enable VLAN tagging: 25 - On host added dummy interface: # ip link add name dummy_interface type dummy - Put host in maintenance/up to reload the new nic - Hosts tab -> Network interfaces -> setup hosts networks Added the network net25 to dummy interface [OK] - Added more networks (-> Networks -> New) and more dummy interface at host - Put host in maintenance/up to reload the new nic - Added bond via Hosts tab -> Network interfaces [X] Save network configuration so far ok, moved the host to maintenance and rebooted. Host is back with the interfaces but vdsm doesn't start (opened below bug). vdsm cannot start - iproute2: device ovirtmgmt already exists; can't create bridge with the same name https://bugzilla.redhat.com/show_bug.cgi?id=1064530 -- Cheers Douglas

[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.
