10Gb Networking with OVN

by Beau Sapach

Hello everyone, I see here: https://www.ovirt.org/blog/2017/09/introducing-ovirt-4.2.0/ that version 4.2 will have OVN support. Does anyone know if this will allow VMs to take advantage of 10Gb networking without needing SR-IOV? -- Beau Sapach *System Administrator | Information Technology Services | University of Alberta Libraries* *Phone: 780.492.4181 | Email: Beau.Sapach(a)ualberta.ca <Beau.Sapach(a)ualberta.ca>*

Re: [ovirt-users] Some major problems after 4.2 upgrade, could really use some assistance

by Jayme

This is becoming critical for me, does anyone have any ideas or recommendations on what I can do to recover access to hosted VM? As of right now I have three hosts that are fully updated, they have the 4.2 repo and a full yum update was performed on them, there are no new updates to apply. The hosted engine had updates as well as a full and complete engine-setup, but did not return after being shut down. There must be some way I can get the engine running again?

Persistence on oVirt-Nodes

by FERNANDO FREDIANI

Quick questions about Nodes (in order to not hijack the other thread). As they don't have much notion of persistence how can I: - To have a simple configuration backup in order for, if the Operating System disk fails I reinstall the Node, restore the config and everything comes back up fine ? Backing up /var /etc and /root folders would be enough or anything else ? - If I install something custom (e.g: A Zabbix Agent) it works until the host receives a new system/image Upgrade. Is there any way that can be made persistent ? - As oVirt-Nodes are images, if I install them in a SD Card or USB Stick will be there much write to disk still ? Other than possibly the logs and configuration changes what else could be written to disk ? If so a Feature Request to solve this would be to mount the logs partition in RAM as the Node boots and logrotate that. If someone needs to keep it more time can always use rsyslog Thanks Fernando

Non-RHEL RPMs gone after RHV-H upgrade

by Colin Coe

Hi all We're running RHV 4.1.6. Yesterday I upgraded the RHV-H nodes in our DEV environment to 20180102 and found that all the non-RHEL RPMs are now gone. Their associated config files in /etc are still there. The RPMs in question were from HPE SPP plus a monitoring system client (Xymon). I had thought that non-RHEL RPMs would persist after a host upgrade. Am I wrong on this? Thanks CC

oVirt Node 4.1 question, writing files to /root and RPMs

by Matt Simonsen

Hello all, I read at https://www.ovirt.org/develop/projects/node/troubleshooting/ that "Changes made from the command line are done at your own risk. Making changes has the potential to leave your system in an unusable state." It seems clear that RPMs should not be installed. Is this accurate for https://www.ovirt.org/node/ ? We have added smartctl and hpacucli in order to do disk and RAID monitoring. So far our node servers have retained changes across reboots, which is the primary reason I'm wondering if perhaps this applies to an older version of oVirt Node. If what we have been doing is not supported, what is the suggested method to do do hardware monitoring (in particular disks)? Thanks Matt
