[Users] Increase core or socker for vCPU
by Tejesh M 06 Mar '14

06 Mar '14

Hi, I have a basic doubt, while increasing vCPU for a VM in RHEV-M, do we need to increase core or sockets? For instance, if someone asks for 2vCPU then should i make it 2 socket x 1 core or 1 socket x 2 core.. I do understand that it depends on application too to choose. but i'm asking in general. Sorry, if its not relevant to this forum. Thanks

[Users] [oVirt Test Day 3] Reports installation
by Martin Perina 06 Mar '14

06 Mar '14

Hi, I tried to install oVirt Reports during test day 3 with these results: 1) Centos 6.5 - epel and jpackage6 repositories needs to be enabled - installation and setup worked fine (set everything at default) - after creating dc and cluster and adding host to engine, reports were able to show data, so it looks OK 2) Fedora 19 - installation and setup worked fine (set everything at default) - after creating dc and cluster and adding host to engine, reports were able to show data, so it looks OK Martin Perina

by Sandro Bonazzola 06 Mar '14

06 Mar '14

Hi, have you got some free time and do you want to get involved in oVirt integration? Here are a couple of bugs you can hopefully fix in less that one day: Bug 1059950 - If cluster=Default does not exist in hosted-engine it will fail and timeout Bug 1072664 - engine-setup.manual create database fail. Is this the first time you try to contribute to oVirt project? You can start from here [1][2]!

by Tejesh M 06 Mar '14

06 Mar '14

Hi, While creating VM from Template via Web Admin portal, the default provisioning is Clone. But while doing the same via API its is doing Thin provisioning. Can someone share there view. org.ovirt.engine.sdk.entities.Template templateData = new Template(); templateData.setName(templateName); org.ovirt.engine.sdk.entities.Cluster clusterData = new Cluster(); clusterData.setName(clusterName); org.ovirt.engine.sdk.entities.VM vmDataForCreate = new VM(); vmDataForCreate.setName(vmName); vmDataForCreate.setCluster(clusterData); vmDataForCreate.setTemplate(templateData); api.getVMs().add(vmDataForCreate); -- Thanks & Regards Tejesh

[Users] [ANN] oVirt 3.4.0 RC Test Day - Today Mar 6th
by Sandro Bonazzola 06 Mar '14

06 Mar '14

Hi all, today Mar 6th we have oVirt 3.4.0 RC test day. On this day all relevant engineers will be online ready to support any issues you find during install / operating this new release. Just make sure you have 1 hosts or more to test drive the new release. If you're curious to see how it works, this is your chance. Thanks again for everyone who will join us tomorrow! Location #ovirt irc channel Please communicate here to allow others to see any issues What In this test day you have a license to kill ;) Follow the documentation to setup your environment, and test drive the new features. Please remember we expect to see some issues, and anything you come up with will save a you when you'll install final release Remember to try daily tasks you'd usually do in the engine, to see there are no regressions. Write down the configuration you used (HW, console, etc) in the report etherpad[1]. Documentation Release notes: http://www.ovirt.org/OVirt_3.4.0_release_notes Features pages links: http://bit.ly/17qBn6F If you find errors in the wiki please annotate it as well in report etherpad [1] Prerequisites / recommendations Use CentOS or RHEL 6.5 only. 6.4 is unsupported due to various issues (sanlock, libvirt, etc). Use Fedora 19 only. Fedora 20 is unsupported for running the engine due to various issues (jboss / wildfly) but may be used as hypervisor. Latest RPMs repository to be enabled for testing the release are listed in the release notes page [2]. Note: on Fedora you'll need to enable fedora-virt-preview repository for getting latest libvirt rpms. Note: on EL6 you'll need to enable EPEL repository. NEW issues / reports For any new issue, please update the reports etherpad [1] Feature owners, please make sure: your feature is updated and referenced on release page [2]. you have testing instruction for your feature either on test day page [3] or in your feature page. your team regression testing section is organized and up to date on test day page [3].

[Users] Data Center Non Responsive / Contending
by Giorgio Bersano 05 Mar '14

05 Mar '14

Hi everyone, I'm asking for help again as testing my setup I put myself in a situation in which I can't get out. Layout: two hosts, an iSCSI storage, the engine installed as a "regular" KVM guest on another host (external to the oVirt setup). All CentOS 6.5, oVirt 3.4.0beta3. One DC ("Default"), one Cluster ("Default"), default storage type iSCSI. Moreover, ISO domain is another "external" KVM guest exposing an NFS share; Export Domain is in fact a VM in this Cluster. This is a preproduction setup. Yesterday all was running fine until I needed to do some hardware maintenance. So I decided to put the two hosts in maintenance from the webadmin then shutdown them in the usual way. Engine was left operational. Later i booted again one host, waited some time then tried to activate it (from the webadmin) without success. Even switching on the second host didn't change anything. Now the Data Center status toggles between "Contending" and "Non Responsive". None of the hosts is SPM and if I choose "Select as SPM" in the webadmin the result is this popup: ---------- Operation Canceled ---------- Error while executing action: Cannot force select SPM: Storage Domain cannot be accessed. -Please check that at least one Host is operational and Data Center state is up. ---------- The two hosts are operational but the DC isn't up (downpointing red arrow - "Non Responsive", hourglass - "Contending"). Storage domains are in "Unknown" state and if I try to "Activate" the Master Data Domain its status becomes "Locked" and then it fails with these events: . Invalid status on Data Center Default. Setting status to Non Responsive . Failed to activate Storage Domain dt02clu6070 (Data Center Default) by admin Connectivity seems OK. iSCSI connectivity seems OK. I'm almost certain that if I had left one host active I would have had zero problems. But I also think shutting down the full system should not be a problem. In the end I restarted the ovirt-engine service without results (as expected). Any thought? Logs needed? TIA, Giorgio.

[Users] SD Disk's Logical Volume not visible/activated on some nodes
by Boyan Tabakov 05 Mar '14

05 Mar '14

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --kNwttSRPs68koQxvdSI5KDEeiPmQG9f68 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello, I have ovirt 3.3 installed on on FC 19 hosts with vdsm 4.13.3-2.fc19. One of the hosts (host1) is engine + node + SPM and the other host2 is just a node. I have an iSCSI storage domain configured and accessible from both nodes. When creating a new disk in the SD, the underlying logical volume gets properly created (seen in vgdisplay output on host1), but doesn't seem to be automatically picked by host2. Consequently, when creating/booting a VM with the said disk attached, the VM fails to start on host2, because host2 can't see the LV. Similarly, if the VM is started on host1, it fails to migrate to host2. Extract from host2 log is in the end. The LV in question is 6b35673e-7062-4716-a6c8-d5bf72fe3280. As far as I could track quickly the vdsm code, there is only call to lvs and not to lvscan or lvchange so the host2 LVM doesn't fully refresh. The only workaround so far has been to restart VDSM on host2, which makes it refresh all LVM data properly. When is host2 supposed to pick up any newly created LVs in the SD VG? Any suggestions where the problem might be? Thanks!

[Users] Fwd: [Engine-devel] Tweaking backup/restore of engine
by Sven Kieske 05 Mar '14

05 Mar '14

Hi, forwarding this mail to the users list: Does somebody do engine(DB) backups and restores without the content of the audit_log table? This one can grow quite large if you are using REST like it's meant to be (stateless, so a single login/logout event for every REST-Call). This can quickly accumulate 100.000 events and more. Does anybody got any experience with restoring engine without these logs? I'm talking about disaster recovery, so I want just to backup the necessary data to make the engine run. -------- Original-Nachricht -------- Betreff: [Engine-devel] Tweaking backup/restore of engine Datum: Mon, 3 Mar 2014 16:25:39 +0000 Von: Sven Kieske <S.Kieske(a)mittwald.de> An: engine-devel(a)ovirt.org <engine-devel(a)ovirt.org> Hi, currently all events are stored in the table audit_log which all gets saved when you use the engine-backup shell script. the event log is full of these login lines (engine 3.3.2): 25652 fdfc627c-d875-11e0-90f0-83df133b58cc admin@internal 00000000-0000-0000-0000-000000000000 \N \N \N \N \N 2014-01-20 06:39:17.222+01 USER_VDC_LOGIN 30 0 User admin@internal logged in. f \N \N 00000000-0000-0000-0000-000000000000 \N \N \N \N 00000000-0000-0000-0000-000000000000 \N oVirt -1 30 f \N this makes the log and db grow very large when you use the REST-API to query ovirt for various data. Is this necessary for a working restore? It would be cool if we could tweak the engine-backup tool to just dump necessary tables so you don't have to restore events from the past no one is interested in. How does ovirt react, if I do not restore the content of the audit_log table? If this works (restore without audit_log) I would prefer to have this code upstream in ovirt git so I don't have to maintain my own backupscript. Would it be possible to extend the existing backupscript with a switch to not backup logs? Currently it's just "all" or "just db". I also recall that there shouldn't occur multiple login events any more since ovirt 3.3. but it still seems to be the case. I also do not understand how you would manage a stored authentication via REST as REST is stateless. I would appreciate any feedback or thoughts on this topic. -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

[Users] Importing Glance images as oVirt templates
by Oved Ourfalli 05 Mar '14

05 Mar '14

Hi all! In oVirt 3.4 we extended the integration with Glance, allowing to import Glance images as oVirt templates. We also added a public Glance repository to be used by oVirt deployments. A reference to this repository is automatically added in 3.4, so you'll see it in the UI by default, under the name "ovirt-image-repository". This repository currently contains only a small set of images, but we hope to extend it soon. The right way to use the Fedora and CentOS images that are there is to import them as templates, create VMs from them, and use cloud-init to configure them. I wrote a blog post on how to use it. Have a look at http://ovedou.blogspot.co.il/2014/03/importing-glance-images-as-ovirt.html Will be happy to hear your comments and answer your questions, Oved

[Users] SPICE causes migration failure?
by Ted Miller 05 Mar '14

05 Mar '14

I just got my Data Center running again, and am proceeding with some setup & testing. I created a VM (not doing anything useful) I clicked on the "Console" and had a SPICE console up (viewed in Win7). I had it printing the time on the screen once per second (while date;do sleep 1; done). I tried to migrate the VM to another host and got in the GUI: Migration started (VM: web1, Source: s1, Destination: s3, User: admin@internal). Migration failed due to Error: Fatal error during migration (VM: web1, Source: s1, Destination: s3). As I started the migration I happened to think "I wonder how they handle the SPICE console, since I think that is a link from the host to my machine, letting me see the VM's screen." After the failure, I tried shutting down the SPICE console, and found that the migration succeeded. I again opened SPICE and had a migration fail. Closed SPICE, migration failed. I can understand how migrating SPICE is a problem, but, at least could we give the victim of this condition a meaningful error message? I have seen a lot of questions about failed migrations (mostly due to attached CDs), but I have never seen this discussed. If I had not had that particular thought cross my brain at that particular time, I doubt that SPICE would have been where I went looking for a solution. If this is the first time this issue has been raised, I am willing to file a bug. Ted Miller Elkhart, IN, USA

Re: [Users] oVirt 3.5 planning
by Juan Pablo Lorier 05 Mar '14

05 Mar '14

Hi, I'm kind of out of date at this time, but I'd like to propose something that was meant for 3.4 and I don't know it it made into it; use any nfs share as either a iso or export so you can just copy into the share and then update in some way the db. Also, make export domain able to be shared among dcs as is iso domain, that is an rfe from long time ago and a useful one. Attaching and dettaching domains is both time consuming and boring. Also using tagged and untagged networks on top of the same nic. Everybody does that except for ovirt. I also like to say that tough I have a huge enthusiasm for ovirt's fast evolution, I think that you may need to slow down with adding new features until most of the rfes that have over a year are done, because other way it's kind of disappointing opening a rfe just to see it sleeping too much time. Don't take this wrong, I've been listened and helped by the team everytime I needed and I'm thankful for that. Regards,

[Users] Recommended way to disconnect and remove iSCSI direct LUNs
by Boyan Tabakov 04 Mar '14

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --VQiJjAHh4OqnW9GHojIg6s1LSghwPBraw Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable Hello, I have ovirt 3.3.2 running with FC19 nodes. I have several virtual machines that use directly attached iSCSI LUNs. Discovering, attaching and using new LUNs works without issues (vdsm needed some patching to work with Dell Equallogic, as described here https://sites.google.com/a/keele.ac.uk/partlycloudy/ovirt, but that's a separate issue). Also live migration works well between hosts and the LUNs get properly attached to the migration target host. However, I don't see any way to disconnect/remove LUNs that are no longer needed (e.g. VM is removed). What is the recommended way to remove old LUNs, so that the underlying iSCSI sessions are disconnected? Especially if a VM has been migrated between hosts, it leaves the LUNs connected on multiple nodes. Thank you in advance!

[Users] Setting up an ovirt-node
by Andy Michielsen 04 Mar '14

04 Mar '14

Hello, I did a clean install of a ovirt-node with the iso provided from ovirt. Everything went fine until I logged on with the admin user and configured the ovirt-engines address. Now I don't have any network connection any more. I have 2 nic's available and defined only the first one with a static IP. When I check the network settings in the admin menu it tells me I have serveral bond devices. If I log on with a root user it states that under /etc/sysconfig/network_scripts that there is a ifcfg_em1, ifcfg_ovirtmgmt and a ifcfg_brem1. The two last devices use the same static ip that I defined on the ifcfg_em1. How can I get my network back up and runnig as I will need this to connect to the engine which is running on an other server. Kind regards.

Hello, Which iso should I use to install an ovirt-node ? What the difference between the el and fc versions. (I'm installing the engine on a centos 6.5 minimal server.) Which version should I use. Kind regards.
