self hosted setup with answer file
by Greg Swift 17 Feb '15

17 Feb '15

So i've been playing with standing up a self hosted instance of oVirt. I'm using an answer file that i generated first time I tried running it (so that I can provision w/ ansible) I've run into 2 problems. 1: i have to specify the jboss home manually from the cli (didn't see an answer equivalent), even though the ovirt jboss package is installed. 2: Generally speaking it seems to be ignoring several of the answer file config entries. My answers tell it to 'confirm settings' and it runs non-interactively. Plus all the local storage configs seem to be ignored. I'm running ovirt-engine-3.5.1.1-1.el7.centos.noarch Any suggestions? thanks

Port mirroring outside traffic into a VM?
by Chris Adams 16 Feb '15

16 Feb '15

I have a network traffic monitor that is on a physical machine right now. It has two network interfaces: one with an IP on a regular switch port, and one without an IP on a switch port that is the target of a port mirror/monitor session for the desired VLAN. I'd like to move this system to an oVirt VM (I'm running 3.5.1). Is this the right way to go about it (and still have the VM migratable)? - I have several hosts with extra network interfaces; pick at least a couple, connect them to switch ports that are configured for mirror/monitor session. - In oVirt admin console, choose the Networks tab, click New. Give the network a name (like "monitor"), leave VLAN tagging de-selected and VM Network selected. Under the Cluster section, de-select Required (because the mirror won't go to all hosts). Click OK to create. - Click on the network, select the vNIC Profiles tab, edit the default profile and select Port Mirroring. - Go to the Hosts tab. For each host with a port mirror, click on the host, then choose the Network Interfaces tab and Setup Host Networks. Drag the new network to its attached port, click the pencil, and set Boot Protocol to None. - Go to the Virtual Machines tab. Click on the VM, choose the Network Interfaces tab, and click New. Choose the monitor network in the Profile. -- Chris Adams <cma(a)cmadams.net>

Client-quorum not met - Distributed-Replicate gluster volume
by Wesley Schaft 16 Feb '15

16 Feb '15

Hi, I've set up 4 oVirt nodes with Gluster storage to provide high available virtual machines. The Gluster volumes are Distributed-Replicate with a replica count of 2. The extra volume options are configured: cat /var/lib/glusterd/groups/virt quick-read=off read-ahead=off io-cache=off stat-prefetch=off eager-lock=enable remote-dio=enable quorum-type=auto server-quorum-type=server Volume for the self-hosted engine: gluster volume info engine Volume Name: engine Type: Distributed-Replicate Volume ID: 9e7a3265-1e91-46e1-a0ba-09c5cc1fc1c1 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: gluster004:/gluster/engine/004 Brick2: gluster005:/gluster/engine/005 Brick3: gluster006:/gluster/engine/006 Brick4: gluster007:/gluster/engine/007 Options Reconfigured: cluster.quorum-type: auto storage.owner-gid: 36 storage.owner-uid: 36 cluster.server-quorum-type: server network.remote-dio: enable cluster.eager-lock: enable performance.stat-prefetch: off performance.io-cache: off performance.read-ahead: off performance.quick-read: off network.ping-timeout: 10 Volume for the virtual machines: gluster volume info data Volume Name: data Type: Distributed-Replicate Volume ID: 896db323-7ac4-4023-82a6-a8815a4d06b4 Status: Started Number of Bricks: 2 x 2 = 4 Transport-type: tcp Bricks: Brick1: gluster004:/gluster/data/004 Brick2: gluster005:/gluster/data/005 Brick3: gluster006:/gluster/data/006 Brick4: gluster007:/gluster/data/007 Options Reconfigured: cluster.quorum-type: auto performance.quick-read: off performance.read-ahead: off performance.io-cache: off performance.stat-prefetch: off cluster.eager-lock: enable network.remote-dio: enable storage.owner-uid: 36 storage.owner-gid: 36 cluster.server-quorum-type: server network.ping-timeout: 10 Everything seems to be working fine. However, when I stop the storage network on gluster004 or gluster006, client-quorum is lost. Client-quorum isn't lost when the storage network is stopped on gluster005 or gluster007.

I've added a "dummy" gluster node for quorum use (no bricks, only running glusterd), but that didn't help. gluster peer status Number of Peers: 4 Hostname: gluster005 Uuid: 6c5253b4-b1c6-4d0a-9e6b-1f3efc1e8086 State: Peer in Cluster (Connected) Hostname: gluster006 Uuid: 4b3d15c4-2de0-4d2e-aa4c-3981e47dadbd State: Peer in Cluster (Connected) Hostname: gluster007 Uuid: 165e9ada-addb-496e-abf7-4a4efda4d5d3 State: Peer in Cluster (Connected) Hostname: glusterdummy Uuid: 3ef8177b-2394-429b-a58e-ecf0f6ce79a0 State: Peer in Cluster (Connected) The 4 nodes are running CentOS 7, with the following oVirt / Gluster packages: glusterfs-3.6.2-1.el7.x86_64 glusterfs-api-3.6.2-1.el7.x86_64 glusterfs-cli-3.6.2-1.el7.x86_64 glusterfs-fuse-3.6.2-1.el7.x86_64 glusterfs-libs-3.6.2-1.el7.x86_64 glusterfs-rdma-3.6.2-1.el7.x86_64 glusterfs-server-3.6.2-1.el7.x86_64 ovirt-engine-sdk-python-3.5.1.0-1.el7.centos.noarch ovirt-host-deploy-1.3.1-1.el7.noarch ovirt-hosted-engine-ha-1.2.5-1.el7.centos.noarch ovirt-hosted-engine-setup-1.2.2-1.el7.centos.noarch vdsm-gluster-4.16.10-8.gitc937927.el7.noarch The self-hosted engine is running CentOS 6 with ovirt-engine-3.5.1-1.el6.noarch Regards, Wesley

firewalld and NetworkManager support
by Nathanaël Blanchet 16 Feb '15

16 Feb '15

Hi all, I've just installed a new el7 datacenter, and many questions came up with. I was surprised to see that all vdsm generated ifcfg files were NM_CONTROLLED=no, and NetworkManager was disabled in systemd. The same for firewalld, disabled for regular iptables files. Will that default el7/fedora features be adpated to ovirt in a next release?

[SLA] can't start vm due to "host did not satisfy internal filter Memory."
by Sven Kieske 16 Feb '15

16 Feb '15

Hi, I haven't got any trouble with ovirt for a long time but know I hit some wall: Situation: local storage DC with a single vm in it. ovirt-engine version 3.3.3 (yeah I know, old..) error i get: vm does not boot anymore. excerpt from engine.log: 2015-02-09 13:25:06,926 ERROR [org.ovirt.engine.api.restapi.resource.AbstractBackendResource] (ajp--127.0.0.1-8702-14) Operation Failed: [Cannot run VM.

why is it called vdsm?

Why is it called vdsm and not something a little more descriptive and project-related, like "ovirt-agent"? Greg Sheremeta Red Hat, Inc. Sr. Software Engineer, RHEV Cell: 919-807-1086 gshereme(a)redhat.com

mixing tagged and untagged vlans on a same interface
by Nathanaël Blanchet 16 Feb '15

16 Feb '15

Hi all, On a standalone libvirt/KVM, I've been used to mix tagged and untagged vlans on the same interface, the untagged vlan dedicated to the physical interface em1 and the other tagged ones to VLAN em1.X. I've just installed a new datacenter with an untagged ovirtmgmt and then realized that I've been prevented from attaching additional vlan to the same inetrface. Is there a reason for that, knowing that nothing should technically be wrong?

Issues adding a custom fencing agent
by Tobias Fiebig 15 Feb '15

15 Feb '15

Heho, i currently try to get an intelmodular server working with fencing, following: http://lists.ovirt.org/pipermail/devel/2014-February/006525.html and http://www.ovirt.org/Custom_Fencing BaseInfo: Scientific Linux 6.6 (engine/hosts) Ovirt 3.5 I added an agent with: engine-config -s CustomVdsFenceType="intelmodular" /etc/init.d/ovirt-engine restart The issue is, that the added agent always results in: 2015-02-05 19:31:08,963 ERROR [org.ovirt.engine.core.bll.FenceExecutor] (ajp--127.0.0.1-8702-1) Failed to run Power Management command on Host , no running proxy Host was found. and: Test Failed, There is no other host in the data center that can be used to test the power management settings. Picking any other agent, results in the execution of the binary on one of the cluster hosts. (which, of course fails). Replacing one of theses default-fences with a bash-script echoing $@ to a file prints nothing, additional programs (id, env) however do print sth. to the given file. Any ideas on how to continue this, to ideally get fence_intelmodular working? With best Regards, Tobias

Problem on the manager
by Massimo Mad 14 Feb '15

14 Feb '15

I have a problem on my oVirt managers, the problem is that the directory / var/lib/pgsql/data fills. Initially thinking that my file system /var/log 2Gb was too small now have increased to 4Gb and is refilled. How can I prevent this from happening, it may be due to the fact that I have implemented the backup manage with the script of backup.sh oVirt. Regards Massimo
