Hello Friends of oVirt, I'd setup a oVirt enviroment (hosted-engine) behind a proxy. But I can't add any additional Host to my Cluster. I'm phase of testing (SELinux Permissive, No firewall) All the machines are CentOS 7.1 When I try to add a Host, the operation it's OK, but don't see the Data Master Storage and the operation at the ends fails, and the additional host it's Non Operational. FQDN Engine: ovirt.udistritaloas.edu.co FQDN Host with the Host-Engine and with the Data Master Storage: patascoy.udistritaloas.edu.co FQDN Additional host: sotara.udistritaloas.edu.co This is the resume: 2015-Apr-13, 17:08 Failed to connect Host Sotara to Storage Pool OAS 2015-Apr-13, 17:08 Host Sotara cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center OAS.

Can't export template with 3.5.1
by Bob Doolittle 13 Apr '15

13 Apr '15

I created template from a VM, which completed successfully. Now I am trying to export that template, and I get an error: "Failed to complete copy of Template Centos6 to Domain xion2-tmpexport". Any suggestions? There is plenty of free space on disk. I have attached my VDSM log and my engine and server logs. I am using Fedora 20 for the (single) host and the self-hosted engine, oVirt 3.5.1.1-1 Thanks, Bob I've linked 2 files to this email: vdsm.log <https://db.tt/MEbYnz2Z>(20.6 MB)Dropbox <https://www.dropbox.com/>https://db.tt/MEbYnz2Z engine.log <https://db.tt/13hMN54l>(2.4 MB)Dropbox <https://www.dropbox.com/>https://db.tt/13hMN54l Mozilla Thunderbird <http://www.getthunderbird.com> makes it easy to share large files over email.

oVirt 3.5 on Ubuntu? [oVirt Dockerized]
by Moran Goldboim 13 Apr '15

13 Apr '15

Deploying oVirt engine has never been so easy. Checkout oVirt dockerized projects on docker hub[1] and github[2]. You can find some overview on oVirt-dockerized blog[3] Please let me know if you find it useful. Cheers, Moran.

Re: [ovirt-users] about testing scenario

I am not aware of a "best practice" ntp doc for ovirt. There is plenty of information about this over the net, search e.g. for "time sync in virtual machines" or something like that. AFAIK, one thing you should not do, for the time being at least, is assume that if you keep your hosts' clock synced, the VMs' will be too automatically. > I will need my VMs sincronized in time, and also the engine and the native > hosts. > How do you manage that ? > Is there a ntdp runing on some VM isolated from the ntpd running in the > engine ? I think most people just treat VMs just as physical ones and run their favorite ntp client everywhere, pointing both hosts and guests at their organization's ntp server(s). That one (the organization's ntp server) some people tend to put on physical hardware (not a VM), which I guess makes some sense. Best, -- Didi

NFS Storage: domain locked by NFS-provider?
by shimano 13 Apr '15

13 Apr '15

Hi all, I tried to configure NFS Storage Domain with load balance by configuring different IPs on Hosts for the same NFS-hostname and running few NFS servers on those machines (NFS exports from MooseFS cluster). Unfortunatelly after correct add and attach Storage Domain, all Hosts are switching to Non-operational because of problems with access to that Storage Domain. Is oVirt making any locks on NFS SD's metafile?

self hosted storage engine disaster recovery procedure
by Ron V. 13 Apr '15

13 Apr '15

Hello, I am getting familiar with oVirt and using the self-hosted engine on an iSCSI SAN and so far everything seems quite impressive. I am trying to document a disaster recovery mecanism using a full OS backup as well as a engine backup as described at http://www.ovirt.org/Ovirt-engine-backup I am unclear however how to prepare the existing iSCSI LUN to receive the data restore. I am able to destroy the engine and the VMs continue to run, however I am unclear how I can free the host lock on that LUN, format it and re-install on it. Is there a howto/document I can refer to in order to do this? I am looking for info as to how I can re-install a functional engine from a backup in the case of data-corruption or any other disaster that could happen on the iSCSI LUN set aside for the engine, and a means to re-install on that LUN should the need be, without having to power down the VMs or worse, power everything down and re-install everything from scratch. How can I boot a CentOS install disk and have the previous's engine LUN as a install target, and then boot that installed OS to restore the engine backup data? Thanks in advance, Ron
