Snapshots - Preview button greyed out
by Leo David 16 Aug '18

16 Aug '18

Hi Everyone, I am encountering an issue on my oVirt 4.2 self-hosted engine installation. Suddenly the "Preview" button in snapshots menu became inactive, I just cannot revert any previews snapshots. This feature worked fine over the last month, but now it seems to be just inactive. Any thoughts on this ? Thank you very much ! Leo -- Best regards, Leo David

Patches for L1FT?
by Eduardo Mayoral 16 Aug '18

16 Aug '18

Hi, For mitigation of the recently announced L1TF vulnerability, is it sufficient to update the compute nodes to the updated kernel? Are any other updates to KVM / vdsm / ovirt-engine required? Also, for the concurrent variant. Should we disable hyperthreading altogether? Is there any remediation (even if expensive from a performance view), that can be enabled? Thanks for your help! -- Eduardo Mayoral.

Do I need to set VM vnic profile for GlusterFS network?
by Jayme 16 Aug '18

16 Aug '18

I followed this guide to get my three node HCI cluster up and running: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluste… The docs were a bit out of date but most things matched up. I have configured an internal GlusterFS network on a separate subnet on 10Gbe switch and have set it as the glusterFS and migration network. Is this all that is needed to be done for all glusterFS traffic to pass through that network or must the glusterFS vnic profile also be selected for each VM? I'm not sure if my VMs should be using ovirtmgmnt vnic or GlusterFS vnic.

storage domain sync problem and fail to run vm after change LUN mapping
by dvotrak 16 Aug '18

16 Aug '18

Environment: Ovirt version: 4.2.5 Centos 7.5 During a planned maintenance window, multipath configuration was changed according to the storage vendor guidelines. The new configuration modify user_friendly_names from no to yes, so the multipath -ll output changed from this "360060160a6213400fa2d31acbbfce511 dm-8 DGC" to this: "mpathh (360060160a6213400fa2d31acbbfce511) dm-8 DGC". After this change, the following errors are displayed: 1) when attempting to start a VM with direct LUN: Failed to run VM <VMNAME> on Host <HYPERVISOR> VM <VMNAME> is down. Exit message: Bad volume specification <LUN_ID> Inspecting the VM disk, the lun id remains the previous one (360060160a6213400fa2d31acbbfce511) insted of the new one (mpathh) Remove/detach and re-add/re-attach the disk to VM doesen't help. 2) randomly: Storage domains with IDs [<ID>] could not be synchronized. To synchronize them, please move them to maintenance and then activate. Moving it to maintenance and then activate it doesen't help. Inspecting storage domain luns, almost all change the lun id to the new ones (mpathXX), but this one remain in "the old style" (maybe because lun_id is a primary key and this one was already taken?) Any idea on how to resolve these problems? Thanks Sent with [ProtonMail](https://protonmail.com) Secure Email.

Timezone error when trying to import VMWare created .ova
by jthomasp＠gmualumni.org 15 Aug '18

15 Aug '18

I get: Cannot import VM. Invalid time zone for given OS type. Attribute: vm.vmStatic I found an old thread here: https://lists.ovirt.org/pipermail/users/2014-January/019363.html But it states the issue was resolved in 3.3.1. Running oVirt 4.2.5.1 The VM has the proper time zone set and the clock synced with a time server. Hardware compatibility of the VM has been upgraded to VM Version 9 as recommended on the oVirt IRC channel. I appreciate any help! Thanks, Jason

"ISCSI multipathing" tab isn't appear in datacenter settings
by navigator80＠tut.by 15 Aug '18

15 Aug '18

Hello. We have 6 servers in our cluster, which use 2 storage through iSCSI connections. Each storage has 2 nodes. Each node has 2 IP addresses in two different VLANs. Each host has 2 networks in this VLANs, so, the iSCSI traffic is separated from other types of traffic. I want to turn on iSCSI multipathing beetween hosts and storage, but "ISCSI multipathing" tab isn't appear in datacenter settings. But when I'm add a additional storage domain, "ISCSI multipathing" tab is displaying. If I want to detach this additional storage domain, "ISCSI multipathing" tab is disappear at once. Why is this happening?
