How Many Logical networks supported
by p.staniforth＠leedsbeckett.ac.uk 12 Oct '18

12 Oct '18

Hello, We are currently using oVirt for teaching and one of our requirements is for security such as IR PEN testing etc. We would like to create individual logical networks with a network profile that includes port mirroring, this is to reduce the amount of traffic they can see and the targets available. We are looking to to add VMs into Affinity Groups so they will run on the same host to make the port-mirror work but don't no if there is a limit on the number of logical networks that is allowed/practical. Thanks, Regards, Paul S.

Adding a new Host to Cluster via oVirt Manager fails with "No Route to Host"
by Markus Frei 12 Oct '18

12 Oct '18

Hello everybody I am facing the following issue currently. I am trying to add a new physical host to our cluster via oVirt Management Engine Web GUI. Apparently communication between oVirt Engine and the corresponding host is working well, since all necessary packages will be installed successfully. But after a while the installation process fails with the error "No Route to Host" and the host ends up in state "non operational". I checked the network interfaces via Web GUI (Host -> Network Interfaces -> Setup Host Networks) and none of the interfaces are present. In my opinion this is the main problem. It seems the interfaces are not being recognized. I tried using a bond interface and a single interface with static configuration (IP, DNS, Gateway). None of them worked. Further Log Errors: WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (EE-ManagedThreadFactory-engine-Thread-1688) [] Host 'HOSTNAME' is not responding.

VLAN tagging with external provider networks
by anurag.porripireddi＠bigswitch.com 12 Oct '18

Hi, I see that checking the "External provider" box whilst creating networks clears and grays out VLAN tagging. Is VLAN tagging for external provider networks not supported? Thanks, Anurag

Resizing ovirt-engine disk
by Baptiste Agasse 12 Oct '18

12 Oct '18

Hi all, We have a running ovirt installation on a SAN backend (installed in 4.0 via appliance, then updated to 4.1 and now in 4.2). At installation time we choose (or didn't change) the disk size and this one is about 10GB: fdisk -l /dev/vda Disk /dev/vda: 10.7 GB, 10737418240 bytes, 20971520 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk label type: dos Disk identifier: 0x000686fc Device Boot Start End Blocks Id System /dev/vda1 * 2048 20971519 10484736 83 Linux Can we grow the ovirt-engine disk like any other managed VM ? And if not, how can we grow the ovirt-engine disk out of standard installation procedure ? Have a nice day. Cheers. Baptiste.

vNIC tagged VLANs and Bond VLANs support
by greg＠santconsulting.com 12 Oct '18

12 Oct '18

Hi, We have a need to create a VLAN tagged vNIC over a Bond interface and allow that same VLAN to be accessible to a VM who's NIC is the same Bond. Our testing shows that once you create the VLAN tagged vNIC, the VLAN is no longer available to VMs over the bond. Below is the config we are trying to create. VM#1 oVirt Interface = Bond0 Logical Network = vNIC70 (tagged VLAN 70) VM Host Interface = eth0 VM#2 oVirt Interface = Bond0 Logical Network = Bond0 / Host based VLAN 70 tag as sub-interface (eth0.70) VM Host Interface = eth0.70 Is there a way around this issue while supporting the requirement? Thanks!

Info on HCI single host
by Gianluca Cecchi 11 Oct '18

11 Oct '18

Hello, following this reference guide: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Single_node… after having run with success the gdeploy based gluster setup, there is Setting up Hosted Engine Use the Ansible based installation flow of Hosted Engine to set up oVirt within a virtual machine. The storage details should be provided as type: glusterfs and connection path as: <hostname>:/engine (Replace hostname with address of host on which installation is carried out) What does exactly mean "Use the Ansible based instalation" ? Does it mean using cockpit web ui? In this casae I suppose I have to choose: Hosted Engine Deploy oVirt hosted engine on storage that has already been provisioned Correct? Thanks, Gianluca

10 Oct '18

Hello! I am interested to run ovirt in docker container. It was noticed that there is an official repo for it: https://github.com/oVirt/ovirt-container-engine Unfortunately it did not get an update for 2 years (4.1). Can anyone help with the required answers/entrypoint/patch files for the new 4.2 ? Thanks!
