Copying VM from one datacenter to another
by Gabi C 29 Apr '14

29 Apr '14

Hello! De facto; I have two datacenter: - 1 with one host, configured with local storage, just added in the engine; - 1 with 3 host, 2 shared storage domain, 1 ISO and 1 Export For some backup reasons ( cold backup) I want to copy machines from second Datacenter to the Local-storage one. Is there some documented way of doing this? Any hints, thoughts, similar experience? Thanks!

[Users] Failure to connect to engine with Nagios
by Juan Hernandez 29 Apr '14

29 Apr '14

Hello, We are having some trouble with the Nagios plugin for oVirt. From time to time it stops working and it isn't able to connect to the engine. The error that we get apparently indicates a failure to read the file where the session cookie is stored: RHEV CRITICAL: Can't connect to RHEVM-API. Unsuccessful stat on filename containing newline at /usr/lib/nagios/plugins/check_rhev3 line 1411. Any suggestion on how to diagnose/solve this issue?

Hosted Engine started VM Multiple Times
by Andrew Lau 29 Apr '14

29 Apr '14

Hi, I added a new node to my hosted cluster today, only one other node was active in the cluster at that time. It was running the hosted-engine, however during the install it's agent died and when the second node came up. It started the hosted-engine, causing the hosted-engine to be run on both nodes. Has anyone had this happen? This seems very dangerous, as both VMs were running simultaneously.. data corruption alert! Andrew.

Re: [ovirt-users] [ovirt-devel] Feature Page: Mac Pool per DC

Now for users(a)ovirt.org indeed. ----- Original Message ----- From: "Yevgeny Zaspitsky" <yzaspits(a)redhat.com> To: "Martin Mucha" <mmucha(a)redhat.com> Cc: users(a)ovrit.org, devel(a)ovirt.org Sent: Sunday, April 27, 2014 2:29:46 PM Subject: Re: [ovirt-devel] Feature Page: Mac Pool per DC Martin, I'd like to propose a different approach on how the ranges to be defined and stored. Discussing this feature with Moti raised the alternative UX design: Defining ranges could be added as a left-tab on create DC dialog and a sub-tab on an existing DC. It would be a table of start and end address fields and we can add a calculated # of MACs in the range and/or summary for the DC. Also that will make string parsing unneeded, prevent possible user mistakes in the string format and make possible validating every field of the range on the UI side easier. As you can see on the screenshot you've attached even a single range doesn't fit to the text box. In case of multiple ranges managing them in a single line textbox would be very uncomfortable. A range is an object with at least 2 members (start and end). And we have few of these for each data center. Storing a collection of the objects in a single field in a relational DB seems a bit awkward to me. That has few disadvantages: 1. is not normalized 2. make data validation nearly impossible 3. make querying the data very difficult 4. is restraining our ability to extend the object (e.g. a user might like to give a description to a range) So IMHO a satellite table with the FK to storage_pool would be a more robust design.

Add a Direct Lun via rest API (Oivrt 3.3.5)
by Gary Lloyd 28 Apr '14

28 Apr '14

Hello I was just wondering if anyone would be able to help me figure out if there is a way to login to an ISCSI target (EqualLogic) and add its associated volume as a Direct LUN via the REST api. I have figured out how to add an existing Direct LUN to a vm. I have created a volume on the SAN and then I am attempting to upload some xml to the API: curl -v -u 'admin@internal:mypass' -H "Content-type: application/xml" -d @disk.xml https://ovirt-test/disks/ --insecure cat disk.xml <disk> <alias>direct_lun</alias> <interface>virtio</interface> <format>raw</format> <lunStorage> <type>iscsi</type> <logical_unit> <address>10.0.0.1</address> <port>3260</port> <target>iqn.2001-05.com.equallogic:0-1cb196-cff1c713e-e2a004dfcc65357b-dev-directlun</target> </logical_unit> </lunStorage> </disk> At the moment the API is returning with a HTTP 400: <fault> <reason>Incomplete parameters</reason> <detail>Disk [provisionedSize|size] required for add</detail> </fault> Is it possible to achieve my goal via the API ? Thanks *Gary Lloyd* ---------------------------------- IT Services Keele University -----------------------------------

cloud-init woes w/ templates
by Andrew Lau 27 Apr '14

27 Apr '14

Hi, Has anyone had any success with cloud-init and templates with ovirt 3.4? So far, it seems to be able to configure things like networks etc. But when it goes to do with passwords, it must be set again in the "run once" or in the "Initial Run" even if "Use already configured password" is set. Another thing, why is it only setup to change the root password? By default cloud-init will block root, so nearly all images need to be modified ie. sed -i 's/disable_root: 1/disable_root: 0\nchpasswd: { expire: False }/g' /etc/cloud/cloud.cfg Otherwise, you'll login and it'll ask you to change your password. Defeats the purpose of setting it through cloud-init? I'm also not being able to just set an SSH key, it insists a password otherwise the key won't get uploaded. Finally, templates seem to be lacking validation. Where "Initial Run" and "Run Once" will give the red box if you have the wrong syntax while templates don't care. Thanks, Andrew

Unable to edit virt-v2v import VM - 3.4.0
by Trey Dockendorf 27 Apr '14

27 Apr '14

I just imported a VM using the following command: virt-v2v -ic qemu+ssh://root@kvm1.DOMAIN/system -o rhev -os 192.168.202.245:/tank/ovirt/import_export --network ovirtmgmt --vmtype server syslog.DOMAIN I successfully imported it in the oVirt web UI, but when I try to edit the VM I get the following message, "Cannot edit VM. Cannot set single display device via VNC display.". I noticed the "Single PCI" option in the Console section is checked, when none of my other VMs have this checked. Another VM I imported using version 3.3.x does not have this checked. The checkbox is greyed out, so I can't make any modifications in the "Edit" dialog. Any suggestions? For issues regarding importing from KVM using virt-v2v, what logs are useful besides engine.log? Thanks - Trey

Network Security / Seperation
by squadra 26 Apr '14

26 Apr '14

Hi Folks, i am currently looking for a way to isolate each vms network traffic so none can sniff others network traffic. currently i am playing around with the neutron integration, which gives me more question marks than answers for now (even documentation seems to be incomplete / outdated). Is there any other solution, which does not require to create a new vlan for each vm, to make sure that noone can sniff others traffic? Cheers, Juergen -- Sent from the Delta quadrant using Borg technology!

oVirt 3.4 - Hosted Engine: Cluster Reboot procedure
by Daniel Helgenberger 26 Apr '14

26 Apr '14

--=-QguCZheGA74Z2DLSRg8u Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable Hello ovirt-users, after playing around with my ovirt 3.4 hosted engine two node HA cluster I have devised a procedure on how to restart the whole cluster after a power loss / normal shutdown. This assumes all HA-Nodes have been taken offline. This also applies partly to rebooted HA nodes. Please feel free do ask questions and/or comment on improvements. Most of the things should be obsoleted by future updates anyway. Note 1: The problem IMHO seems to be the non connected nfs storage domain, resulting in the HA-Agent crash / hang. The ha-broker service should be up and running all the time. Please check this. Note 2:=20 My setup consists of two nodes; 'all nodes' means the task has to be performed on every node HA node in the cluster. Node 3: By 'Login' I mean SSH or local access. Part A: SHUTDOWN THE CLUSTER Prerequisite: oVirt HE cluster running, should be taken offline for maintenance: 1. In oVirt, shutdown all VM's except HostedEngine. 2. Login to one cluster node and run 'hosted-engine --set-maintenance --mode=3Dglobal' to put the cluster into global maintenance 3. Login to ovirt engine VM and shut it down with 'shutdown -h now' 4. Login to one cluster node and run 'hosted-engine --vm-status' to check if the engine is really down.=20 5. Shutdown all HA nodes subsequently. Part B: STARTING THE CLUSTER Prerequisite: oVirt HE cluster down, NFS storage server running and exporting the vdsm share. 1. Start all nodes and wait for them to boot up. 2. Login to one cluster node. Check the status of the following services: vdsm, ovirt-ha-agent, ovirt-ha-broker. The status should be all are running except ovirt-ha-agent is in 'locked' state and down. 3. Check 'hosted-engine --vm-status', this should result in a python stack trace (crash). 4. On all cluster nodes, connect the storage pool: 'hosted-engine --connect-storage'. Now, 'hosted-engine --vm-status' runs and reports 'up to date: False' and 'unknown-stale-data' for all nodes. 5. On all cluster nodes, start the 'ovirt-ha-agent' service: 'service ovirt-ha-agent start' 6. Wait a few minutes for the ha-broker and the agent to collect the cluster state. 7. Login to one cluster node. Check 'hosted-engine --vm-status' until you have cluster nodes 'status-up-to-date: True' and 'score: 2400' 8. If the cluster was shutdown by yourself and in global maintenance, remove the maintenance mode with 'hosted-engine --set-maintenance --mode=3Dnone'. Now, the system should do a FSM reinitialize and start the HostedEngine by itself.=C2=B9 If it was not in maintenance (eg. power fail) the engine should be started as soon as one host gets a score of 2400. Part C: STARTING A SINGLE NODE Prerequisite: oVirt HE cluster up, HostedEngine running. One ha node was taken offline by local maintenance in oVirt and rebooted. 1. Follow steps 1-5 of Part B 2. In oVirt, navigate to Cluster, Hosts and activate the node previously in maintenance. --- 1 I observed the following things: * If you use the command 'hosted-engine --vm-shutdown' instead of loging in to the ovirt HE and do a local shutdown, the Default Data Center is set to non - responsive and being Contented after the reboot. I highly suspect an unclean shutdown by running the command. Further, it waits about two min. with the shutdown. * If you use the command 'hosted-engine --vm-start' on a cluster in global maintenance, wait for successful start ({'health': 'good', 'vm': 'up', 'detail': 'up'}) and remove the maintenance status, the engine gets restarted once. By removing the maintenance first and letting ha-agent do the work, the engine is not restarted.

does SPM can run over ovirt-engine host ?
by Tamer Lima 25 Apr '14

25 Apr '14

Hello, When I create virtual machine from a template (centos6.5, 2 cores, 8GB mem, 500GB hd) this process takes almost 2 hours. I click on "New VM" button and just select the template and click ok. engine.log show me high network consumption (98%) between engine-server host and SPM host. I tried to make my engine-server host a spm host too, but without sucess. Does SPM can run over on the same ovirt-engine machine ? Am I make something wrong? Or create VM from template is really slow ? my servers : srv-0202 = ovirt-engine , vdsm srv-0203 = spm , vdsm srv-0204 = vdsm These servers are dell blades connected on a 100GB switch. thanks This is what I know about SPM: http://www.ovirt.org/Storage_-_oVirt_workshop_November_2011 = Storage Pool Manager (SPM) A role assigned to one host in a data center granting it sole authority over: - Creation, deletion, an dmanipulation of virtula disk images, snapshots and templates - Templates: you can create on VM as a golden image and provision to multiple VMs (QCOW layers) - Allocation of storage for sparse block devices (on SAN) - Thin provisinoing (see below) - Single metadata writer: - SPM lease mechanism (Chockler and Malkhi 2004, Light-Weight Leases for Storage-Cnntric Coordination) - Storage-centric mailbox - This role can be migrated to any host in data center

Hosted engine datastore crashed on adding a new datastore
by Klas Mattsson 25 Apr '14

25 Apr '14

Hello all, For some reason, when I try to add a second datastore (separate IP and empty share with 36:36 user rights), the share which has got the hosted-engine on it crashes. This of course crashes the hosted engine. When the share is up again, it's not sufficient to create a directory /rhev/data-center/mnt/ with identical name as before and mounting the share there. The hosted-engine still refuses to boot up. The load (pure I/O) on the NFS server goes up to about 11 as well. Any ideas on where I should check?

Storage domain - defining fields
by Gabi C 25 Apr '14

25 Apr '14

Hello! My setup 1 engine Fedora 19 ovirt 3.4 managing 3 nodes Fedora 19 + ovirt 3.4 updated; those nodes acts also as gluster server for 2 storage domains, each domain 3 bricks replicated ( so 3 bricks each). I have one questions regarding the fields one have to complete when defining a new storage domain and its importance. First, field "*Use Host*" - you have to complete with one of the nodes. Of course you can use any of the host in cluster, *but which is its significance/importance*? * If you reboot that node, you suppose to have any issue with the storage?* The same question with field "*Path*" - gluster case - "*Path to gluster volume to mount*" formatted as "HOST:VOLUME" , where host can be the same as above mentioned field- "*Use Host*" or any af the gluster cluster member; *which is its significance/importance?* *Again If you reboot that node, you suppose to have any issue with the storage?* My experience with rebooting these nodes*, *after moving VM's and putting it in Maintenance was good*,* until yesterday, when after such reboot I've got some corrupted VM images, and subsequently I had to restore them. Error message follows : Exit message: cannot read header '/rhev/data-center/mnt/glusterSD/10.125.1.194:gluster__data3/5fe658b1-43ff-4bfd-97d6-28217cf415df/images/321ad473-3741-4825-8ac0-6c416aa8f490/1a21454d-9931-4ed8-ba38-7126528664a1': Input/output error." Did I miss some step(s), beside moving VM's and puting node in maintenace, before reboot one host node, servig also as gluster node? Any hint, link would be appreciated! Thanks!

by Matt . 25 Apr '14

25 Apr '14

Hi All, I'm having an issue with oVirt 3.4 and Foreman 1.5 RC1 at the moment, it does not start/finish a new provisioned VM/Host., it creates it well on oVirt. I'm sure this worked well on a nightly some dags ago and I didn't update it after it. The foreman bug is shown here: http://projects.theforeman.org/issues/5132 What I also see in the engine log is a bunch of admin login errors which I cannot place anywhere: 2014-04-23 20:26:44,203 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-6) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,242 INFO [org.ovirt.engine.core.bll.LogoutUserCommand] (ajp--127.0.0.1-8702-6) [2e4a8183] Running command: LogoutUserCommand internal: false. 2014-04-23 20:26:44,276 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-6) [2e4a8183] Correlation ID: 2e4a8183, Call Stack: null, Custom Event ID: -1, Message: User admin logged out. 2014-04-23 20:26:44,470 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-1) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,510 INFO [org.ovirt.engine.core.bll.LogoutUserCommand] (ajp--127.0.0.1-8702-1) [5d731a43] Running command: LogoutUserCommand internal: false. 2014-04-23 20:26:44,542 INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (ajp--127.0.0.1-8702-1) [5d731a43] Correlation ID: 5d731a43, Call Stack: null, Custom Event ID: -1, Message: User admin logged out. 2014-04-23 20:26:44,575 INFO [org.ovirt.engine.core.bll.LoginUserCommand] (ajp--127.0.0.1-8702-3) Running command: LoginUserCommand internal: false. 2014-04-23 20:26:44,623 INFO [org.ovirt.engine.core.bll.RemoveVmCommand] (ajp--127.0.0.1-8702-3) [708f0b9a] Lock Acquired to object EngineLock [exclusiveLocks= key: 7bfc175c-dbcd-43c9-9549-cde8d3b3b731 value: VM I get the feeling this has something todo with eachother.

Hi, all I created DC, use GlusterFS as the domain type. And created Storage, with storage type "Data/GlusterFS" But VM used FUSE mount point, are not used qemu-glusterfs native integration When i looked at the running KVM processes, i saw -drive file=/rhev/data-center/mnt/ glusterSD/vdsm01.cn.local: local/35c541ad-bd48-4000-ad8f-8539629b7d75/images/9f3ecc5d-5d82-4e83-a89e-b298725e1d63/6a621ecc-715d-4a15-982c-05c618eefd36 But I expect to see -drive file=gluster+tcp:// Fodora 19 oVirt 3.3.4 libvirt 1.0.5 qemu-kvm 1.4.2

Is there any way to accomplish this? Like this, using php or python to post username, password and domain to the user portal. Is re-build and keep the cookie possible?

Spurious error message when the RHEV capacity is maxed out?
by Satya Vempati 24 Apr '14

24 Apr '14

--_000_CF7D45AF5E0Esvempatitintricom_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable We have about 900 vms in a RHEV-M 3.3 installation (3.3.2-0.50.el6ev) with = three hosts. Each VM has 1 socket, 1 core for CPU and 256 MB memory and 2 x 1TB disks + = one 5 GB boot disk. Each host has 2 cpu sockets with 4 cpu cores per socket. When we power on about 250 of these vms, we cannot power on any more vms. Attempting to do so gets the error (in the RHEV-M) console. Bad volume specification {'index': 0, 'iface': 'virtio', 'reqsize': '0', 'f= ormat': 'raw', 'bootOrder': '1', 'volumeID': '14aa7302-7f6d-4b80-922d-3fc09= 0695447', 'apparentsize': '5368709120', 'imageID': '97b1985e-e507-4927-91e9= -7393c7777de5', 'specParams': {}, 'readonly': 'false', 'domainID': '0c7abcc= c-1b97-4b39-ab96-e977a19fac3a', 'optional': 'false', 'deviceId': '97b1985e-= e507-4927-91e9-7393c7777de5', 'truesize': '0', 'poolID': '5849b030-626e-47c= b-ad90-3ce782d831b3', 'device': 'disk', 'shared': 'false', 'propagateErrors= ': 'off', 'type': 'disk'}. This looks like a spurious error, as we can power on the same VM after rebo= oting the hosts. And also, the hosts do not really look maxed out (CPU usage is around 25%, = memory around 50%), but no more vm=92s can be powered on.
