Re: [ovirt-users] oVirt Node ng upgrade failed

Can you grab imgbased.log? To retry, "rpm -e ovirt-node-ng-image-update" and remove the new LVs. "yum install ovirt-node-ng-image-update" from the CLI instead of engine so we can get full logs would be useful On Thu, Nov 23, 2017 at 16:01 Lev Veyde <lveyde(a)redhat.com> wrote: > > ----------

ovirt-node-ng-update
by Nathanaël Blanchet 30 Nov '17

30 Nov '17

Hi all, I didn't find any explicit howto about upgrade of ovirt-node, but I may mistake... However, here is what I guess: after installing a fresh ovirt-node-ng iso, the engine check upgrade finds an available update "ovirt-node-ng-image-update" But, the available update is the same as the current one. If I choose installing it succeeds, but after rebooting, ovirt-node-ng-image-update is not still part of installed rpms so that engine tells me an update of ovirt-node is still available. -- Nathanaël Blanchet Supervision réseau Pôle Infrastrutures Informatiques 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Configuring LDAP backend in non interactive mode
by Luca 'remix_tj' Lorenzetto 30 Nov '17

30 Nov '17

Hello, i'm looking for some examples on how to configure LDAP authn and authz in non interactive mode. I'd like to add some authentication sources immediately after hosted-engine deployment. I've seen that ovirt-engine-extension-aaa-ldap-setup has an option config-append. Help refers to an answer file, but i can't find out how to generate it. All the servers i'm deploying should use the same configurations to access to 3 different active directory servers. Anyone has experiences about this?

Migration from Proxmox to oVirt
by Gabriel Stein 30 Nov '17

30 Nov '17

Hi again! well, I'm trying to migrate all my VMs from Proxmox to oVirt. Proxmox doesn't have libvirt and I can dump the files using vzdump <vm-id> <directory> and the output is a *.vma file I think from Proxmox. I can't even find the files, Proxmox create Logical Volumes for every VM. I converted that to *.qcow2 using qemu-img convert, the conversion worked(at least no errors) but I can't import it using a script that I found on web* and the export storage domain(oVirt didn't found it). I would like to know if there is a way to do that. I read a lot about and found that one could build a conversion server and use virt-v2v to import. But it will require a RH Enterprise for that, right? I don't have a subscription and I would like to know if is possible without the subscription? And sorry for the offtopic question, if there is a "redhat" which would like to answer me privately, if I buy a subscription for 1 Server and I have NN CentOS Servers, it will be possible to use all benefits since I have a valid subscription(of course, support just for the RH Server)? * https://rwmj.wordpress.com/2015/09/18/importing-kvm-guests-to-ovirt-or-rhev/ Thanks in Advance!

by Greg Sheremeta 29 Nov '17

29 Nov '17

Hi everyone, [I should have sent this message sooner -- apologies, and thanks to Martin Sivak for the reminder!] If you're trying out oVirt 4.2 Beta, please check that any existing UI plugins [1] you are using 1. still work (they should!), and 2. look good in the new UI. If something doesn't look quite right with a UI plugin [for example, if it doesn't quite match the new theme], please contact Alexander Wels and me and we can assist with getting it updated.

Update gluster HCI from 4.1.3 to 4.1.7
by Gianluca Cecchi 28 Nov '17

28 Nov '17

Hello, I have an environment with 3 hosts and gluster HCI on 4.1.3. I'm following this link to take it to 4.1.7 https://www.ovirt.org/documentation/how-to/hosted-engine/#upgrade-hosted-en… The hosts and engine were at 7.3 prior of beginning the update. All went ok for the engine that now is on 7.4 (not rebooted yet) Points 4. 5. 6. for the first updated host were substituted by rebooting it I'm at point: 7. Exit the global maintenance mode: in a few minutes the engine VM should migrate to the fresh upgraded host cause it will get an higher score One note: actually exiting from global maintenance doesn't imply that the host previously put into maintenance exiting from it, correct? So in my workflow, before point 7., actually I have selected the host and activated it. Currently the situation is this - engine running on ovirt02 - update happened on ovirt03 Then after exiting from global maintenance I don't see the engine vm migrating to it.

Time management in self hosted engine vm
by Gianluca Cecchi 28 Nov '17

28 Nov '17

Hello, I have a self hosted engine HCI environment that was born in 4.0.5 through the ansible/gdeploy mechanism and then gradually updated to 4.1.7 Now the engine and host are at CentOS 7.4 level. Inside the gdeploy jobs the engine vm was installed through the appliance at the 4.0.5 time. I see in web admin gui that hw clock of engine vm is configured as UTC (so far so good) and the same is inside the OS. And I would like to change it to UTC+1 like the 3 hosts I also see that neither chronyd nor ntpd are installed on engine vm. Can I fix the situation the normal os level way: - timedatectl set-timezone "Europe/Rome" - install and configure chronyd or better not to configure time sync in engine vm? Thanks, Gianluca

Just wanted to ask if anyone has tested it in any environment and made any comparison, specially for packet forward (e.g: running Virtual Routers or Virtual Firewalls with virtio) or packet dropping as well. One doubt I have and if someone could clarify is: Should I enable DPDK in the Host any traffic forwarded to any VMs will automatically benefit from this performance gain of DPDK or there additional steps that need to be put in place inside the VM when sharing a physical Network Interface ?

Upgrading from Hosted Engine 3.6 to 4.X
by Cam Wright 28 Nov '17

28 Nov '17

Hi there, We're looking to upgrade our hosted engine setup from 3.6 to 4.0 (or 4.1)... We built the 3.6 setup a couple of years ago with Fedora 22 (we wanted the newer-at-the-time kernel 4.4) on the hosts and engine, but when we move to 4.X we'd like to move to EL7 on the engine (as that seems to be the supported version) and to the oVirt Node ISO installer on the hypervisors. We've got only four hosts in our oVirt datacentre, configured in two clusters. Our current idea is to take a backup of the oVirt database using the backup-restore tool, and to take a 'dd' of the virtual disk too, for good measure. Then upgrade the engine to 4.X and confirm that the 3.6 hosts will run, and then finally piecemeal upgrade the hosts to 4.X using the oVirt Node ISO installer. Looking at this page - https://www.ovirt.org/documentation/self-hosted/chap-Maintenance_and_Upgrad… - it seems the 'hosted-engine --upgrade-appliance' path is the best way to do this... but because our hosts are running Fedora instead of EL, I think that makes this option moot to us. Is what I've suggested a valid upgrade path, or is there a more sane way of going about this? -C Cam Wright - Systems and Technical Resource Administrator CUTTINGEDGE / 90 Victoria St, West End, Brisbane, QLD, 4101 T + 61 7 3013 6200 M 0420 827 007 E cwright(a)cuttingedge.com.au | W www.cuttingedge.com.au /SYD /BNE /TYO -- This email is confidential and solely for the use of the intended recipient.

Thanks for the reply. Yes I am aware of that and it seems that's what I will have to do. I have no problem with VDSM managing the file, I just wish it didn't automatically load local storage devices into multipathd. It doesn't. Recent multipath releases do. Does it bother you in any way?

Auto-starting VMS in a all-in-one / confusion.
by CRiMSON 27 Nov '17

27 Nov '17

I've been digging thru mailing lists and blogs and I'm a bit confused about how you have VMs auto-start after a reboot in a ovirt system that is setup as all-in-one. >From what I can gather this can be achieved via some startup scripts (or a rc.local foo). But there is no setting inside the WebUI that can be set to achieve this? Or have I missed something.

"Enable Discard" for Ceph/Cinder Disks?
by Matthias Leopold 27 Nov '17

27 Nov '17

Hi, according to http://docs.ceph.com/docs/luminous/rbd/qemu-rbd/ the use of Discard/TRIM for Ceph RBD disks is possible. Openstack seems to have implemented it (https://www.sebastien-han.fr/blog/2015/02/02/openstack-and-ceph-rbd-discard/) In oVirt there is no option "Enable Discard" for Cinder Disks (when choosing IDE or VirtIO-SCSI driver), even when i set "report_discard_supported = true" in Cinder. Are there plans for supporting this in the future? Can i use it right now with custom properties (never tried this before)? thx matthias

Some roles management issues
by Paolo Margara 27 Nov '17

27 Nov '17

Hi list, access policy to my system has changed recently and now I've to manage non admin users allowed to create VMs only on selected resources. Unfortunately this condition was not expected years ago when the system was installed and so all VNic profiles was created with the option "Allow all users to use this Profile", there is a way to edit this settings after a VNic profile was created or I need to create a new one and set all VMs to use that? The same procedure is applicable also for the network used by the hosted engine? I've tried to remove the "VNicProfileUser" role assigned to "Everyone" for a particular VNic profile but by doing only this users continue to see the logical network in the select box of the VM creation form but they cannot use it getting an error when they effectively create a VM clicking OK (that is quite annoying because it seems a configuration problem). I've also noted that the role "DiskProfileUser" was assigned on storage domain object and to some unknown null object for "Everyone", there is some reason why some roles are assigned to null? I could safely remove them? Greetings, Paolo

extending cloud Images in oVirt
by Artem Tambovskiy 27 Nov '17

27 Nov '17

I have a question indirectly releted to Ovirt. I need to move one old setup into VM running in oVirt cluster. The VM was based on on Debian 8.9, so I took a Debian cloude image from https://cdimage.debian.org/cdimage/openstack/8.9.8-20171105/ uploaded it into my cluster and attached it to VM. All looks good but ... the disk shows only 2G and indeed ned more disk space. I tried to edit and add more space - and it didnt work. Any ideas how to extend those cloud images? Regards, Artem
