Snapshots - Preview button greyed out
by Leo David
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

Patches for L1FT?
by Eduardo Mayoral
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!

storage domain sync problem and fail to run vm after change LUN mapping
by dvotrak
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

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