does SPM still exist?
by yam yam 25 Mar '20

Hello, I heard some say SPM disappeared since 3.6. nevertheless, SPM still exists in oVirt admin portal or even in RHV's manual. So, I am wondering whether SPM still exists now. And could I know how to get more detailed information for oVirt internals?? is the code review the best way?

Data Center, Cluster and Storage Domains show as "Down" after backup and restore
by anton.louw＠voxtelecom.co.za 24 Mar '20

24 Mar '20

Hi Everybody, So I did a full backup of our HE, redeployed and restored. After the restore, I ran engine-setup on the newly deployed HE. I can access the the environment as per normal, the only issue is that everything still shows as "down", this includes hosts and VMs? Is there something I need to do in order to get everything to display as "Up" again? Thanks

storage allocation of template
by yam yam 24 Mar '20

24 Mar '20

Hello, I want to know whether a base disk image is physically copied whenever the VM is created from a template. I've just created a VM based on template with 1 disk and checked VM's virtual disk images. there were (1)base image copied? from the template, (2)new delta image. Here, (1) image was identical to that of the template and I know that image is used as read-only mode. So, I am wondering why base (disk) image is inefficiently copied instead of directly referencing template's image as backing file.

safe to have perf and dstat on ovirt node?
by Gianluca Cecchi 23 Mar '20

23 Mar '20

Hello, I would need to have on ovirt node these three packages: - ipmitool - perf - dstat Comparing latest RHVH (4.3.8) and latest ovirt-node-ng (4.3.9) I see that: - ipmitool is present on both - perf is present as an installable package in RHVH and not in ovirt-node-ng - dstat is not available in any of them Why the difference about perf? Is it safe to install perf and dstat on ovirt-node-ng taking them from CentOS updates? This is for a lab and the packages would be used to compute some metrics about performance of the node. Thanks, Gianluca

Re: Moving Hosted Engine
by Joseph Goldman 23 Mar '20

Hi Anton, I believe so - but I believe you can do a hosted-engine deploy with the backup file specified so it auto-restores with it. I need to try it on a test system I haven't done much DR testing yet. My builds have been rushed into production due to time constraints, and although I backup and ship off-site so I have it all I actually haven't done a full breakdown and re-restore yet :/ I'll be interested to know how you go, if you dont mind.

Can't connect storage domain when using VLAN
by Brian Dumont 23 Mar '20

23 Mar '20

Hello, First post! I'm trying to add a nfs storage domain with VLAN tagging turned on the logical network. It errors out with "Error while executing action Add Storage Connection: Problem while trying to mount target". I am able to attach to this nfs export without vlan tagging. I have also verified that I can attach to this nfs export with vlan tagging using a non-ovirt rhel host. Here's my config: - Logical network created at Data Center - Enable Vlan Tagging - ID 15 - Not a VM Network - Cluster status - Network - Up - Assign all - checked - Require - checked - no other boxes checked Host status - Host 1 and Host 2 each show - Status - up - BootP - None (same issue with static IP's) - LinK Layer info shows VLAN ID 15 on switch port Appreciate any help! Brian

bonding and SR-IOV
by Nathanaël Blanchet 23 Mar '20

23 Mar '20

Hello, I successfully attached VF to a VM on a single PF nic following https://access.redhat.com/articles/3215851. I want the vm with VF to be migratable, but the nic hotplug/replug is too long. So I tested the mode 1 bonding (active-backup) with a virtio nic following this https://www.ovirt.org/develop/release-management/features/network/liveMigra… On a single PF, the resilience tests with migration are correct with 1 or 2 second downtime. But now I want to do the same on a typical host with LACP PF: Considering vlan13, I must bond a virtio nic on a brv13/brv13 profile with SR-IOV/brv13 profile as the primary interface. Everything work when the primary interface is brv13/brv13 profile (work as a traditionnal bridge config), but not when changing on the SR-IOV/brv13 profile. I know in this case that the SR-IOV profile is connected to a LACP interface, but does it mean that I have to configure the VF vnic in the VM to be part of the LACP(bond1) as a single member and in that case to do active-backup bond0 with two members bond1 and brv13 nic? Hope to be clear enough.
