Hi Ovirt, We are using Ovirt 4.1 selfhosted engine attach nfs storega as data/iso/export, we have one image which we want to import (manageiq-ovirt-fine-4.qc2). We did copy to our export location (/export/3157c57b-8f6a-4709-862a-713bfa59899a) and chnage the owner ship to (chown -R 36:36 manageiq-ovirt-fine-4.qc2)issues is we are not able to see at ovirtUI-->>Strorage-->>export-->>VM Import nither at Template Import. At the same time not able to see error at logs. Regards Techieim

When i try to move a specific disk between storage domains i get an error. 2017-12-08 11:26:05,257-06 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-41) [] Permutation name: 8C01181C3B121D0AAE1312275CC96415 2017-12-08 11:26:05,257-06 ERROR [org.ovirt.engine.ui.frontend.server.gwt.OvirtRemoteLoggingService] (default task-41) [] Uncaught exception: com.google.gwt.core.client.JavaScriptException: (TypeError) __gwt$exception: <skipped>: Cannot read property 'F' of null at org.ovirt.engine.ui.uicommonweb.models.storage.DisksAllocationModel$3.$onSuccess(DisksAllocationModel.java:120) at org.ovirt.engine.ui.uicommonweb.models.storage.DisksAllocationModel$3.onSuccess(DisksAllocationModel.java:120) at org.ovirt.engine.ui.frontend.Frontend$2.$onSuccess(Frontend.java:233) [frontend.jar:] at org.ovirt.engine.ui.frontend.Frontend$2.onSuccess(Frontend.java:233) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.OperationProcessor$2.$onSuccess(OperationProcessor.java:139) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.OperationProcessor$2.onSuccess(OperationProcessor.java:139) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$5$1.$onSuccess(GWTRPCCommunicationProvider.java:269) [frontend.jar:] at org.ovirt.engine.ui.frontend.communication.GWTRPCCommunicationProvider$5$1.onSuccess(GWTRPCCommunicationProvider.java:269) [frontend.jar:] at com.google.gwt.user.client.rpc.impl.RequestCallbackAdapter.onResponseReceived(RequestCallbackAdapter.java:198) [gwt-servlet.jar:] at com.google.gwt.http.client.Request.$fireOnResponseReceived(Request.java:237) [gwt-servlet.jar:] at com.google.gwt.http.client.RequestBuilder$1.onReadyStateChange(RequestBuilder.java:409) [gwt-servlet.jar:] at Unknown.eval(webadmin-0.js@65) at com.google.gwt.core.client.impl.Impl.apply(Impl.java:296) [gwt-servlet.jar:] at com.google.gwt.core.client.impl.Impl.entry0(Impl.java:335) [gwt-servlet.jar:] at Unknown.eval(webadmin-0.js@54) All the other disks i can move. The issue here is how i got this storage domain into ovirt i think. I set up a new cluster using 4.1 coming from 3.6. I imported a domain from the 3.6 cluster. I am trying to move this disk to one of the new storage domains on the 4.1 cluster. Any help would be greatly appreciated

In my case it detects volFormat=4, Could it be something similar to the bugzilla above? Can it change anything if exporting with NFS 4.2 or using oVirt 4.2? I think that if one has big qcow2 disk files that he/she desire to migrate into oVirt, the process could be optimized Thanks, Gianluca

Really short version ( I can't find the link to the ovirt doc at the moment) Put hosted engine in to global maintenance and power off the vm (hosted-engine command). On one of your physical hosts, make a copy of he config and update the memory cp /var/run/ovirt-hosted-engine-ha/vm.conf . vim vm.conf Then start hosted engine with the new config hosted-engine --vm-start --vm-conf=./vm.conf On 11 December 2017 at 10:36, Roberto Nunin <robnunin(a)gmail.com> wrote: > > > 2017-12-11 10:32 GMT+01:00 Maton, Brett <matonb(a)ltresources.co.uk>: > >> Hi Roberto can you check how much RAM is allocated to the HE VM ? >> >> >> virsh -c qemu:///system?authfile=/etc/ovirt-hosted-engine/virsh_auth.conf >> >> virsh # dominfo HostedEngine >> >> >> The last update I did seems to have changed the HE RAM from 4GB to 4MB! >> > > > Yes, you're right...... > > virsh # dominfo HostedEngine > Id: 191 > Name: HostedEngine > UUID: 6831dd96-af48-4673-ac98-f1b9ba60754b > OS Type: hvm > State: running > CPU(s): 4 > CPU time: 9053.7s > Max memory: 4096 KiB > Used memory: 4096 KiB > Persistent: yes > Autostart: disable > Managed save: no > Security model: selinux > Security DOI: 0 > Security label: system_u:system_r:svirt_t:s0:c201,c408 (enforcing) > > >> >> On 11 December 2017 at 09:08, Simone Tiraboschi <stirabos(a)redhat.com> >> wrote: >> >>> >>> >>> On Mon, Dec 11, 2017 at 9:47 AM, Roberto Nunin <robnunin(a)gmail.com> >>> wrote: >>> >>>> Hello all >>>> >>>> during weekend, I've re-tried to deploy my 4.2_rc lab. >>>> Everything was fine, apart the fact host 2 and 3 weren't imported.

4-2rc hosted-engine don't boot error:cannot allocate kernel buffer
by Roberto Nunin 11 Dec '17

11 Dec '17

Hi after successfully deployed fresh 4.2_rc with ovirt node, I'm facing with a blocking problem. hosted-engine won't boot. Reaching the console via vnc hook, I can see that it is at initial boot screen, but for any OS release available, I receive: [image: Immagine incorporata 1] then [image: Immagine incorporata 2] googling around, I'm not able to find suggestions. Any hints ? Thanks -- Roberto

Best Practice Question: How many engines, one or more than one, for multiple physical locations
by Matt Simonsen 11 Dec '17

11 Dec '17

Hello all, I read with Gluster using hyper-convergence that the engine must reside on the same LAN as the nodes. I guess this makes sense by definition - ie: using Gluster storage and replicating Gluster bricks across the web sounds awful. This got me wondering about best practices for the engine setup. We have multiple physical locations (co-location data centers). In my initial plan I had expected to have my oVirt engine hosted separately from each physical location so that in the event of trouble at a remote facility the engine would still be usable. In this case, our prod sites would not have a "hyper-converged" setup if we decide to run GlusterFS for storage at any particular physical site, but I believe it would still be possible to use Gluster. In this case oVirt would have a 3 node cluster, using GlusterFS storage, but not hyper-converged since the engine would be in a separate facility. Is there any downside in this setup to having the engine off-site? Rather than having an off-site engine, should I consider one engine per physical co-location space? Thank you all for any feedback, Matt

Scheduling daily Snapshot
by Jason Lelievre 08 Dec '17

Hello, What is the best way to set up a daily live snapshot for all VM, and have the possibility to recover, for example, a specific VM to a specific day? I use a Hyperconverged Infrastructure with 3 nodes, gluster storage. Thank you,
