[Users] connecting to oVirt/RHEV VMs through proxy and the oVirt API
by i iordanov 31 Oct '14

31 Oct '14

Hello, My apologies for cross-posting, but this discussion concerns both mailing lists, I think. In Opaque, I recently started setting the proxy property of SpiceSession from a console file, as is done in remote-viewer, in order to support installations where the nodes are not "visible" from the point of view of the client. However, then I remembered that I have not seen the proxy property being available through the oVirt/RHEV API. I looked at the latest remote-viewer code, and I looked through the oVirt/RHEV API documentation, and indeed, I see no way to get proxy information other than through the console.vv file. If I am correct, then this means that both Opaque and remote-viewer cannot connect to VMs behind a proxy unless a console.vv file is used, which also means that since console.vv files are unobtainable through the User Portal on mobile devices, mobile devices effectively cannot at all connect to such VMs if the user is not an Administrator. Would it be possible to expose the proxy parameter through the API? I couldn't find a bug opened about this, but it doesn't mean it isn't there :). Thanks! iordan -- The conscious mind has only one thread of execution.

NFS Storage domain backup
by Mohyedeen Nazzal 31 Oct '14

31 Oct '14

Hi , I'm using NFS storage domain, is it possible to backup the domain manually? or is there an api in ovirt which support this? For manual backup, is possible to use tools like rsync ? or the data will not be consistent ? Any idea of possible solutions for this?;as we don't have dedicated storage box. Thanks, Mohyedeen.

VM Migrate problem on HA Cluster
by N. Vidiadakis 30 Oct '14

30 Oct '14

Hello to all, I am trying to build a two-node ovirt cluster, using a VNXe 3150 iSCSI SAN. The two physical machines used for hypervisors are HP DL380p servers, with 128GB RAM and two E5-2630. On both servers I created a 100GB logical volume used for GlusterFS, to install on top of it both the hosted engine used and the ISO repository. Installation was fine, and under Virtualization Manager, the datacenter seems OK and both hypervisors seems to be registered properly. I have also added the two hosts to the VNXe, created some iSCSI LUNs to test the whole platform and created iSCSI bond interfaces to enabled multipathing. My problem is that live VM migration only works to one direction, lets say from server VH1 to VH2, and not backwards. If I try to bring the VM back to VH1, I get the following: ===== Migration failed due to Error: Fatal error during migration (VM: Test_Centos_7, Source: hosted_engine_2, Destination: hosted_engine_1). ===== I cant seem (and to be honest dont know exactly how) to identify something in the log files. I have verified though that both servers are identical, with the same services up, SELinux disabled, firewalls down and ntp enabled and reporting same time. Now, if I powerdown the VM from VH2 and start it up again, it starts OK on VH1. Also, if I try to migrate the Hosted Engine itself, I get: ===== Error while executing action: HostedEngine: Cannot migrate VM. There are no available HA hosts in the VM's Cluster. Cannot migrate VM. There is no host that satisfies current scheduling constraints. See below for details: The host hosted_engine_2 did not satisfy internal filter HA. ===== and I have already enabled HA Reservation on the Cluster properties. Thank you in advance, Nick Vidiadakis

Live Snapshot support on EL 6.6 with oVirt 3.5 now "Inactive" when "Active" on EL 6.5
by Scott Worthington 30 Oct '14

30 Oct '14

On EL 6.5 Host and oVirt 3.5, I was able to create live snapshot (Live Snapshot Support: Active). After upgrading host to EL 6.6, the oVirt UI now reports live snapshot as "Inactive". I have submitted bug 1158469 with more details (package versions, etc). https://bugzilla.redhat.com/show_bug.cgi?id=1158469 I would assume that is it not advisable to upgrade from EL 6.5 to EL 6.6 at this time if you require Live Snapshot support on the Host.

Fwd: [ovirt-devel] usage of the foreman / limitations of puppet
by Sven Kieske 30 Oct '14

Forwarding to the users list, because there seems to be no interest on the devel list :) -------- Forwarded Message -------- Subject: [ovirt-devel] usage of the foreman / limitations of puppet Date: Tue, 28 Oct 2014 16:52:54 +0100 From: Sven Kieske <s.kieske(a)mittwald.de> To: devel(a)ovirt.org <devel(a)ovirt.org> Hi, I just wanted to ask if there are some plans to also support other automation tools like salt, chef, cfengine or others, because puppet is imho not a good tool for large environments performance wise. I noticed there is some support for saltstack in foreman. So this seems to be a first step to extend the support for different configuration management tools. I know RH seems to favor puppet (it's used in the new satellite product) but I don't think it scales well (talking about thousands of hosts to manage). Are there any opinions or plans within the ovirt community regarding this topic? -- Mit freundlichen Grüßen / Regards Sven Kieske Systemadministrator Mittwald CM Service GmbH & Co.

Hosted Engine fail after upgrading to 3.5

Hi. After upgrading from 3.4 to 3.5 (I've followed the official RHEV documentation) the Hosted Engine VM cannot boot up anymore.
