Re: [ovirt-users] oVirt 3.5.3 Host Network Interfaces
by Soeren Malchow 07 Jul '15

07 Jul '15

Dear Michael We actually created the ovirtmgmt and the bond manually upfront and then in the ³Setup Hosts Network² we basically did this again (including setting the IP address), regarding the bonding in the gluster network we did not have a problem, you just drag one interface onto the other and then select the bonding mode, where you can also go for bonding mode TLB or ALB if you choose ³custom² or just LACP if you have switches that support this. Step by Step: - set the engine to maintenance and shut it down - configure the bond on the 2 nics for the ovirtmgmt bridge ( em1+em2 -> bond0 -> ovirtmgmt ) - configure the IP on the bridge - reboot the server and see whethter it comes up correctly - remove maintenance and let engine start - Set up the ovirtmgmt in hosts networks but do not forget to set IP and Gateway as well. Though it should work without this hassle (if the bonding mode on the switch and server is compatible) but this way it is easy to get server and switch in the same mode and working without having to do anything in ovirt first. Hope that helps Regards Soeren On 02/07/15 00:31, "users-bounces(a)ovirt.org on behalf of Prof. Dr. Michael Schefczyk" <users-bounces(a)ovirt.org on behalf of michael(a)schefczyk.net> wrote: >Dear All, > >Having set up a Centos 7 server with Gluster, oVirt 3.5.3 and hosted >engine according to >https://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/, >I was hoping that the NIC management and particularly NIC bond/bridge >capabilities would have improved a bit.

Metadata error on hosted engine (fresh install)
by Matteo 06 Jul '15

06 Jul '15

Hi all, I've activated oVirt 3.5 with the hosted engine setup using CentOS 7 as host and CentOS 6 as engine OS. The storage for the hosted engine is iSCSI. The setup went smooth, I've some vm running on top of it without many issues. Right now I've some issue with hosted engine metadata: if I try to add an additional node, at the end of the deploy sequence it fails with error: Failed to execute stage 'Setup validation': Metadata version 9 from host 5 too new for this agent (highest compatible version: 1) On the first host, "hosted-engine --check-liveliness" confirms that the engine is up (Hosted Engine is up!) , but "hosted-engine --vm-status" fails with a python exception: Traceback (most recent call last): File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main "__main__", fname, loader, pkg_name) File "/usr/lib64/python2.7/runpy.py", line 72, in _run_code exec code in run_globals File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 116, in <module> if not status_checker.print_status(): File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_setup/vm_status.py", line 59, in print_status all_host_stats = ha_cli.get_all_host_stats() File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 155, in get_all_host_stats return self.get_all_stats(self.StatModes.HOST) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 102, in get_all_stats stats = self._parse_stats(stats, mode) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/client/client.py", line 141, in _parse_stats md = metadata.parse_metadata_to_dict(host_id, data) File "/usr/lib/python2.7/site-packages/ovirt_hosted_engine_ha/lib/metadata.py", line 147, in parse_metadata_to_dict constants.METADATA_FEATURE_VERSION)) ovirt_hosted_engine_ha.lib.exceptions.FatalMetadataError: Metadata version 9 from host 5 too new for this agent (highest compatible version: 1) looking into metadata file, which is really a block device (via some symlinks), I see a lot of binary data after plain ascii text. Dumping this device results into a 134MB file. ( if someome is curious, the dump is here: https://cloud.brancaleoni.com/index.php/s/4Lx3M5PXkqhO80N ) Reading other posts where the setup was over nfs was suggested to truncate the file, but this is a device file and I'm not sure what to do. Any hint on where I can look at ? Thanks, Matteo

GlusterFS Hyperconvergence
by Tiemen Ruiten 06 Jul '15

06 Jul '15

Hello, I'm in the planning stage of setting up a new oVirt cluster, where I would prefer to use the local disks of the hypervisors for a GlusterFS storage domain. What is the current recommendation (for version 3.5.x)? I found this presentation which seems to suggest that it's possbile with some caveats: http://www.ovirt.org/images/6/6c/2015-ovirt-glusterfs-hyperconvergence.pdf And a few open bugs: https://bugzilla.redhat.com/show_bug.cgi?id=1177791 https://bugzilla.redhat.com/show_bug.cgi?id=1177775 https://bugzilla.redhat.com/show_bug.cgi?id=1177773 What I can't find is current information on if this setup is already possible with 3.5.x or it's better to wait for 3.6. Could someone enlighten me? -- Tiemen Ruiten Systems Engineer R&D Media

Autostart VM
by Koen Vanoppen 06 Jul '15

06 Jul '15

Hi Guys, I couldn't find anything directly concerning my following question, so If it was asked before, I'm sorry... Is there a way to config ovirt in a way that when you created a new vm, it will automatically boot? Because now, when you create a VM it stays in down state. Kind regards, Koen

how can i setup hosted engine on the ovirt-node-3.5-201504280933
by Zhong Qiang 06 Jul '15

06 Jul '15

I 'm installing oVirt Node using a CD(ovirt-node-iso-3.5-0.999.201504280933.el6.iso),and Ovirt Node is worked. How can i setup hosted engine by using OVirt Node Console?or where can i get the Engine OVA? I can't find any description about this in the " www.ovirt.org". The Console looks like this: " Hosted Engine Setup Hosted Engine: Not configured Engine VM Name: Engine Status: Hosted engine not configured Engine ISO/OVA URL for download: _____________ PXE Boot Engine VM [ ] " Thanks.

Host failed to attach one of the Storage Domains attached to it

This is a multi-part message in MIME format. --------------060503080301050806000704 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello, We have a small oVirt deplopyment, with 2 INTEL CPUs and 1 AMD, therefor we defined 2 clusters. One of the Intel machines is running the management as well (We called this SOL). This deployment is connected to a NAS through NFS shares.
