update from 4.1.9 to 4.2.3 and OVN doubt
by Gianluca Cecchi 23 May '18

23 May '18

Hello, at beginning of 2017 I configured OVN in my oVirt 4.1.0 setup, with the previosulsy described notes, I think the ones here: http://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ At that time OVN was not directly integrated in oVirt setup. Then I applied the updates in minor releases and coming at 4.1.9 level in late January this year. Now I plan to update to 4.2.3. I have doubts related to OVN setup. Will the new 4.2.3 OVN setup conflict with my current 4.1.x setup? WHat do I have to answer in setup related questions and prompt? In fact now, after enabling 4.2 repo and updating the setup itself, during the procedure (that I Canceled right now) I receive these questions: # engine-setup . . .

oVirt: engine backup
by femi adegoke 23 May '18

23 May '18

Reading this: https://www.ovirt.org/documentation/self-hosted/chap-Backing_up_and_Restori… It says the node must be in maintenance mode. I was having a discussion on IRC & they were using this (see link) to backup, it makes no mention of maint mode https://scottlinux.com/2015/08/20/create-daily-rhevm-backups/ https://access.redhat.com/solutions/797463 Question: must the node be in maint mode before engine is backed up?

Hi everyone, I will be restarting several production systems within the following hour to apply security updates. The following services may be unreachable for some period of time: - www.ovirt.org - project website - resources.ovirt.org - package repositories - gerrit.ovirt.org - code review - jenkins.ovirt.org - CI master It will not be possible to submit/review patches, clone repositories or run CI jobs during this period. Package repositories and the website will also be unreachable for a short period of time. I will announce you once the maintenance is complete. -- Regards, Evgheni Dereveanchin

Nginx proxy for Ovirt
by Aziz 22 May '18

22 May '18

Hi All, I'm trying to setup nginx as a reverse proxy in order to access ovirt remotely without having to add the fqdn in SSO_ALTERNATE_ENGINE_FQDNS , the idea is that nginx will handle the fqdn translation from my external FQDN (external.fqdn.net ) to ovirt's fqdn (lab.vdi.net) Is there a way to achieve scenario ? Thank you in advance ? Aziz

Hello, We have an old Windows XP VM, that requires access to a physical serial port for our telephone system. We have this working in VMWare, however, I'm not entirely sure how we would set this up in oVirt? Can someone help please? Kind Regards, Joshua Blake

Use local ansible to talk to engineVM and other vm
by 03ce007＠gmail.com 22 May '18

22 May '18

I have a self-hosted-engine (4.2) running on a centos 7.4 server. I have downloaded ovirt ansible roles from ansible-galaxy and can run them from the server where the engineVM is running and able to deploy new vms, clusters, dc, etc. I have seen the use of ovirt4.py file to target and group hosts which you can target for specific plays. However, the box where self-hosted-engine is running is a physical server but I am looking to run ansible from my local machine instead to manage vms running on engineVM. Is there a way to achieve this? Thank you in advance.
