Bring back "Migrate to other Cluster" feature in GUI
by Matt . 25 Aug '17

25 Aug '17

Hi Guys, As known the feature to Migrate to another cluster is moved from the GUI but available in the API. Is there a possibility to bring it back in the GUI or make it an option we can enable ? When provisioning servers it's nice to migrate to another cluster when you per accident provisioned to the wrong cluster. As this was a real feature, why remove improvements ? I think many of us will appreciate to have it back. Thanks! Matt

Re: [ovirt-users] How to build specific network structure?
by Marcin Mirecki 25 Aug '17

25 Aug '17

Just one more thought about your requirement to have the VM with the firewall on a specific host, I am not quite sure you need this requirement at all. What you could do instead, is create an OVN network that would contain only one vNIC on this VM, and add your NIC (the one going out to the external servers) manually to the appropriate OVN LogicalSwitch (the one matching the OVN network). This way the OVN network would bridge the externally facing NIC to your VM vNIC. OVN would take care of making sure the traffic gets to the appropriate host.

Host non-responsive - All VMs shutdown
by Wesley Stewart 25 Aug '17

25 Aug '17

I have noticed this a couple times now. digging through the logs, it looks like the host decided to become unresponsive: 2017-08-24 12:09:05,365-04 INFO [org.ovirt.engine.core.bll.VdsEventListener] (org.ovirt.thread.pool-6-thread-5) [56defee2] ResourceManager::vdsNotResponding entered for Host 'a1bf54c1-2890-4aae-a23d-c83ea2c664d2', 'Host IP' Caused by: java.net.ConnectException: Connection refused There is a lot more, but I thought dropping it into a pastebin would be better: https://pastebin.com/drPNnsGB It looks like the host stopped responding somehow but I can't quite tell how. Any advice or input would be greatly appreciated!

Ovirt 4.1 testing backup and restore Self-hosted Engine
by wodel youchi 25 Aug '17

25 Aug '17

Hi, I am testing the backup and restore procedure of the Self-hosted Engine, and I have a problem. This haw I did the test. I have two hypervisors hosted-engine. I am used iSCSI disk for the VM engine. I followed the procedure described in the Self-hosted Engine document to execute the backup, I put the first host in maintenance mode, the I create the backup and save it elsewhere. Then I've create a new iscsi disk, I reinstalled the first host with the save IP/hostname, then I followed the restore procedure to get the Manager up and running again. - hosted-engine --deploy - do not execute engine-setup, restore backup first - execute engine-setup - remove the host from the manager - synchronize the restored manger with the host - finalize deployment. all went well till this point, but I have a problem with the VM-engine, it is shown as down in the admin portal. the ovirt-ha-agent cannot retrieve the VM config from the shared storage. I think the problem, is that the hosted-engine storage domain is still pointing to the old disk of the old manager and not the new one. I don't know where is this information is stored, in the DB or in the Manager's config files, but when I click Manager hosted-engine domain, I can see the old LUN grayed and the new one (which is used by the restored Manager) is not grayed. How can I fix this?

oVirt 4.1.5 Finally GlusterFS via lbgfapi

This is a multi-part message in MIME format. --------------B58437AC11A9A7397FEA7AA8 Content-Type: text/plain; charset=utf-8 Content-Transfer-Encoding: 8bit Dear List, finally its there : Ovirt VM's can use native gluster via libgfapi.

But I'm not able to migrate the mashine live to another host in the cluster.

Since gluster is a networked protocol I can't see any reason for it. I followed all the bugs like https://bugzilla.redhat.com/show_bug.cgi?id=1022961 since last year and saw them being worked on. Now I'm really disappointed. Running something like MySQL in a VM via gluster via FUSE is crap. :-( Not being able to migrate machines in an ovirt cluster is crap, too if one wants to stay current. A few VM's on my OVirt are running for ~200 days now while constantly upgrading to latest Ovirt Release. That needs live migration of course.

[ANN] oVirt 4.1.6 First Release Candidate is now available
by Lev Veyde 24 Aug '17

24 Aug '17

The oVirt Project is pleased to announce the availability of the First Release Candidate of oVirt 4.1.6 for testing, as of August 24th, 2017 This update is the sixth in a series of stabilization updates to the 4.1 series. Starting from 4.1.5 oVirt supports libgfapi [5]. Using libgfapi provides a real performance boost for ovirt when using GlusterFS . Due to a known issue [6], using this will break live storage migration. This is expected to be fixed soon. If you do not use live storage migration you can give it a try. Use [7] for more details on how to enable it. This release is available now for: * Fedora 24 (tech preview) * Red Hat Enterprise Linux 7.3 or later * CentOS Linux (or similar) 7.3 or later This release supports Hypervisor Hosts running: * Red Hat Enterprise Linux 7.3 or later * CentOS Linux (or similar) 7.3 or later * oVirt Node 4.1 * Fedora 24 (tech preview) See the release notes draft [3] for installation / upgrade instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available - oVirt Node is already available[4] Additional Resources: * Read more about the oVirt 4.1.6 release highlights: http://www.ovirt.org/release/4.1.6/ * Get more oVirt Project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] https://www.ovirt.org/community/ [2] https://bugzilla.redhat.com/enter_bug.cgi?classification=oVirt [3] http://www.ovirt.org/release/4.1.6/ [4] http://resources.ovirt.org/pub/ovirt-4.1-pre/iso/ [5] http://staged-gluster-docs.readthedocs.io/en/release3.7.0beta1/Features/lib… [6] https://bugzilla.redhat.com/show_bug.cgi?id=1306562 [7] http://www.ovirt.org/develop/release-management/features/storage/glusterfs-… Thanks in advance, -- Lev Veyde Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

Package dependency issue
by Abi Askushi 24 Aug '17

24 Aug '17

Hi all, I have ovirt 4.1 with self hosted engine. I have performed lately yum update -y on the hosts and at next yum update at both hosts I get the following dependency issue: Error: Package: rubygem-fluent-plugin-secure-forward-0.4.5-1.el7.noarch (centos-opstools-release) Requires: rubygem(proxifier) The rubygem-proxifier dependency is already installed: rubygem-proxifier-1.0.3-1.el7.noarch I have tried yum update --skip-broken and rpm -Va --nofiles --nodigest to see if this resolves this but the issue remains. Any idea how to resolve this? Thanx, Abi

Hi. I try setting hosted-engine. I make cluster of two node. I run installation step by step as written in ovirt documentation. I add storage, iso domain, etc. Then i create VM. Everything working, all right. Now i shutdown hosted-engine and my VM also not avaliable. It normal behavior? Or i something doing at wrong?
