Team, Is there anything out there in the darkness of the internet that shows how to attach a sub device to a guest from the host? I cant get this to work at all not even from the guest using spice. Thank you for your time and help. Regards. -- Fernando Fuentes ffuentes(a)txweather.org http://www.txweather.org

Change ovirtmgmt VLAN?
by Chris Adams 18 Nov '15

18 Nov '15

I have an oVirt cluster with 7 hosts. Each host has two ethernet links to a switch stack, bonded together, with several VLANs (including the ovirtmgmt VLAN) on top of the bond. Now I need to get one more VLAN trunked into the cluster, but there's a catch: whoever set up this network initially (pre-oVirt) used the same VLAN ID for the server network and for a network management VLAN. These are two different VLANs but both with the same ID. So, my question: is it feasible to change the ovirtmgmt VLAN ID (e.g. from 15 to 16)? If so, what would be the impact? Would I have to shut down the VMs to do that? -- Chris Adams <cma(a)cmadams.net>

VM physical export
by Nicolas Ecarnot 18 Nov '15

18 Nov '15

Hello, [3.5 here] I'd like to export a VM and its 2 big disks toward an external datacenter. Just for fun, I tried with the usual way : export to NFS, detach, attach from remote, import. But the disk are way too huge and our line is thin. The site is remote but the other town is not that far, so physically bring the data (external hard drive) is an option. I don't know if I can export to .ova or .ovf but I don't remind having seen that in oVirt. I know I can export to NFS and copy the whole NFS hierarchy to the hard drive, then restore it inside the remote NFS export domain, then import. But I don't know the exact needs of this hierarchy, and the remote NFS already contains data I can not wipe. I'm not in a hurry there, just having this issue and looking for the best solution. Experimentation allowed. -- Nicolas ECARNOT

oVirt 3.6 and gluster volumes
by Richard Neuboeck 17 Nov '15

17 Nov '15

This is an OpenPGP/MIME signed message (RFC 4880 and 3156) --wvEvSwxAIdM3VwWQpgacC17A1rTUvCdIv Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: quoted-printable Hi, I'm having some trouble installing oVirt 3.6 hosted engine with gluster. First of here are the questions that arose: Do I need separate gluster volumes for the hosted engine and the other VMs? If yes I'm guessing the same optimizations apply to the /engine volume as to the other volume as described in http://www.ovirt.org/Features/Self_Hosted_Engine_Gluster_Support Post installation the storage tab is completely empty though I did create an NFS ISO domain during the hosted-engine --deploy process. Is that normal behavior? Should the engine gluster volume be manually imported ('Import Domain') or is this volume never visible? If I have a separate VM volume I guess I need to create a 'New Domain'. If I do that the over lay window in the UI that allows me to enter the glusterfs connection details clears. I see an animated circle in the middle but nothing happens. There is no entry in the engine log or the in any host log. If I wait long enough the UI terminates the session and I'm at the login again. Last question (for now, I promise): The engine VM is not visible in the UI. Obviously it's running or otherwise there would be no UI. =46rom a variety of sources I get the impression that this shouldn't be but I'm not sure why the engine VM is not showing itself. Sorry for so many maybe obvious questions but since I'm new to oVirt im still stumbling around in the dark for things that do not work according to plan. In case of what should be shown in the UI I'm still not sure what the plan is. To give some background information about my setup: All machines are running up to date versions of CentOS 7.1 64bit. I've three dedicated machines for the gluster storage. The replica 3 gluster volumes are created on top of thinly provisioned volumes. There are three dedicated hosts for virtualization. On the first I'm trying a hosted-engine --deploy. The other two machines are unused since I didn't get everything working as expected. The engine, installed during the deploy process, is installed from a local ISO Centos image. Installation is done manually. I've created two gists: One listing the commands for the gluster volume: https://gist.github.com/tbihawk/4c92dc246a64990942d3#file-ovirt-gluster-s= etup One listing what I've done to install oVirt: https://gist.github.com/tbihawk/adb0a0e7d2a081d63629#file-ovirt-installat= ion-procedure Any help is highly appreciated since I'm kind of stuck. Thanks!

Crate brick button gray out.
by Iosif Radu 17 Nov '15

17 Nov '15

Hi guys, brand new with ovirt. I'm trying to use it to manage my gluster set-up. For testing purpose I've installed 3 Centos 7 machines, one for the engine and the other two as glusterfs nodes. All machines are using the 3.6 repo version. Both nodes have an extra hard disk to be used by gluster. Everything went smotth, I activated and installed the nodes and I have no errors in engine.log or in deploy logs. My understanding was that I can create bricks and use them to create volumes in ovirt. The extra hard disks I have for nodes are formated as xfs and mounted. I can see them in the engine admin interface but the "create brick" button is grayed out. Thanks.
