by Demeter Tibor 16 May '18

Hi, I would like to change IP subnets of my hosts, but I have a glustered setup and I can't remove/re-add my hosts because "server having gluster volume". What will happen If I do force remove the host? It will kill or stop gluster on host? Thanks Regards, Tibor

Copying/Cloning a VM to another server
by Alex Bartonek 16 May '18

16 May '18

Just trying to make sure there isnt an easier way to do what I'm doing. I dont have an HA environment in my homelab. I have 3 VM's and I wanted to copy them to my backup r710 which runs oVirt 4.2. I basically shut down my VM, exported it to an export domain on my primary r710. Then detached the export domain on the primary. On my "standby" r710 I imported the export domain from the primary r710, attached, activated and imported the VM. Worked as expected. I'm assuming this is the correct way to do so. I've tried Export to OVA but that didnt work like I wanted and I didnt care to keep messing with that option. Thanks -Alex Sent with [ProtonMail](https://protonmail.com) Secure Email.

Hosted Engine Setup error (v4.2.3)
by ovirt＠fateknollogee.com 15 May '18

Engine network config error Following this blog post: https://www.ovirt.org/blog/2018/02/up-and-running-with-ovirt-4-2-and-gluste… I get an error saying the hosted engine setup is "trying" to use vibr0 (192.168.xxx.x) even though I have the bridge interface set to "eno1" Regardless of whether the Edit Hosts File is checked or unchecked, it overwrites my engine IP entry from 10.50.235.x to 192.168.xxx.x The same thing happens whether I set the engine IP to Static or DHCP (I don't have DNS, I'm using static entries in /etc/hosts). Any ideas it "insists" on using "vibr0" instead of "eno1"? **also posted this on IRC

Private VLANs
by Colin Coe 15 May '18

15 May '18

Hi all We running RHEV 4.1.10 on HPE Blade servers using Virtual Connect which talk to Cisco switches. I want to implement private VLANs, does the combination of oVirt + Cisco switches + HPE Virtual Connect work with private VLANs? To be clear, I want to have a couple of logical networks (i.e. VLANs) where the nodes in that VLAN cannot talk directly but must go through the router/firewall. Thanks CC

Ovirt host becomes non_operational
by 03ce007＠gmail.com 15 May '18

15 May '18

I am setting up self-hosted-ovirt-engine (4.2) on centos7.4. While running hosted-engine --deploy script, it fails at "Check host status" with 'host has been set in non_operational status' error. logs on engine vm at /var/log/ovirt-engine/host-deploy shows ansible tasl for "add host" ran successfully, but yet after that the host becomes non_operational! Where can i find more information on this error? Thank you.

[ANN] introducing ovirt-openshift-extensions
by Roy Golan 15 May '18

15 May '18

Hi all, Running Openshift on oVirt seems more and more attractive and is starting to get attention. It is very easy to do so today without needing any special configuration, however, to tighten the integration and to take advantage of the underlying infra provider(ovirt) we can do better. For example, oVirt can connect various storage providers, and serve disk space to containers[1][2]. Also, Openshift can ask oVirt for VMs and deploy them as master or application nodes for its usage, without making the administrator doing all that manually. This project[1] is the home for the ovirt-flexvolume-driver and ovirt-provisioner[3] and merging ovirt-cloudprovider[4] is a work in progress. The code under this repository is work-in-progress and moving quickly, however, it has automation (stdci v2 :)) and is working and does at least what you observe in the demo videos. Yet I highly appreciate if any of you that will try will provide feedback be that #ovirt channel/ mailing list or to report bugs directly in the Github project page <https://github.com/oVirt/ovirt-openshift-extensions> [1] https://github.com/oVirt/ovirt-openshift-extensions [2] https://ovirt.org/blog/2018/02/your-container-volumes-served-by-ovirt/ [3] https://kubernetes.io/docs/concepts/storage/dynamic-provisioning/ [4] https://github.com/rgolangh/ovirt-k8s-cloudprovider Thanks, Roy
