oVirt/RHEV and Oracle
by Gianluca Cecchi 18 Jan '17

18 Jan '17

Hello, any experience on this, both from a technical/performance (where I have no doubts actually) and from a licensing mgmt point of view? I know that eg for vSphere, due to the its newest migration capabilities in version 6.x (both in storage and in computing), one is kind of obliged to license the whole vSphere infrastructure, even if he/she has separate Datacenters dedicated to Oracle..... Any thought or link or Red Hat KB pointers or similar are welcome. Cheers, Gianluca

Delay difference between queries (Python vs REST)

Invitation: Next-generation Node package persistence for oVirt 4.1 @ Tue Jan 24, 2017 8am - 9am (MST) (users@ovirt.org)
by rbarry＠redhat.com 17 Jan '17

17 Jan '17

You have been invited to the following event. Title: Next-generation Node package persistence for oVirt 4.1 oVirt Node is a composed hypervisor image which can be used to provision virtualization hosts for use with oVirt out of the box, with no additional package installation necessary. oVirt Node is upgraded via yum in an A/B fashion, but the installation of a completely new image means that packages which have been installed on a previous version of the hypervisor were lost on upgrades, or required reinstallation. With oVIrt 4.1, oVirt Node will cache and reinstall packages installed with yum or dnf onto the new image, ensuring that customizations made by users or administrators are kept. The advantages of keeping packages across upgrades: - ability to persistently modify oVirt Node with additions for tooling or support - removes the need to build a brand-new image with a modified kickstart to modify oVirt Node - simplified management Session outline: - Next-generation oVirt Node overview - yum API overview - oVIrt Node integration with yum/dnf to persist RPMs across upgrades Session link: https://www.youtube.com/watch?v=VAznsxvZpuk Feature Page: https://www.ovirt.org/develop/release-management/features/node/node-next-pe… When: Tue Jan 24, 2017 8am – 9am Mountain Time - Arizona Where: https://www.youtube.com/watch?v=VAznsxvZpuk Calendar: users(a)ovirt.org Who: * rbarry(a)redhat.com - organizer * users(a)ovirt.org Event details: https://www.google.com/calendar/event?action=VIEW&eid=dWxlaW1rMmI0MHJybHZsO… Invitation from Google Calendar: https://www.google.com/calendar/ You are receiving this courtesy email at the account users(a)ovirt.org because you are an attendee of this event.

Ovirt 4.0.6 fail to set boottype for ovirtmgmt interface
by TranceWorldLogic . 17 Jan '17

17 Jan '17

Hi, I was trying to add host in ovirt 4.0.6 using my cluster mark as OVS. In 4.0.5, it was able to setup ovirtmgmt interface but in 4.0.6 it fail to setup interface. I tried debugging this and found that vdsm generated ifcfg for ovirtmgmt not have boottype as dhcp. And hence it fail to bring host in up state, Here I want to know: Q> How can I ask configure ovirt-engine or vdsm to add boottype in ovirtmgmt interface. In my testing I found a strange behaviour as mention below: 1> In my multiple trial I tried setting ovs property for ovirtmgmt network and then I tried adding host. 2> I observe that VDSM was able to add ovirtmgmt in OVS but this behaviour I observed only once. Q> Please, can someone help me to understand this OVS behaviour, it will help me to setup everything on OVS? OR [ In other word, How to setup ovirtmgmt interface on host on OVS bridge ? ] Thanks, ~Rohit

VM listed twice in oVirt UI
by Doug Ingham 17 Jan '17

17 Jan '17

Hi all, We had some hiccups in our datacenter over the new year which caused some problems with our hosted engine. I've managed to get everything back up & running, however now one of the VMs is listed twice in the UI. When I click on the VM, both items are highlighted & I'm able to configure & manage the VM as usual. The FQDN & other things are picked up from the guest agent & displayed on the UI as usual, however the CPU, RAM & Uptime stats for one of the pair continue to show the stats from when the cluster died. Any ideas? oVirt 4.0.3.7 Gluster 3.8.5 CentOS 7 [image: Inline images 1] Many thanks, -- Doug

Error creating a storage pool
by Sergei Hanus 17 Jan '17

17 Jan '17

Hi, All! When trying to attach iscsi device from my storage system, ovirt complains, that it cannot create a storage pool. In logs I can see only this: ---------------------------------------------------------- RuntimeError(u'Error creating a storage pool: (u"spUUID=3fcace71-cd2b-4ab4-9d64-8ef926ead05a, poolName=hosted_datacenter, masterDom=71b0d510-c24a-49fa-86ec-6b5ebf530140, domList=[u\'71b0d510-c24a-49fa-86ec-6b5ebf530140\', u\'793985b7-9d11-44a4-bf68-4b509a967a52\'], masterVersion=1, clusterlock params: ({\'LEASETIMESEC\': 60, \'LOCKPOLICY\': \'ON\', \'IOOPTIMEOUTSEC\': 10, \'LEASERETRIES\': 3, \'LOCKRENEWALINTERVALSEC\': 5})",)',), <traceback object at 0x35935a8>) ----------------------------------------------------------- I have verified, that this block device can be successfully connected and partitioned on the same server using standard tools (iscsiadm, parted, mount), so, storage system on its own is working fine. My question is: what are requirements for block device in order for it to be compliant with ovirt? I know, that block size must be 512 bytes, but anything else? Thank you in advance, any comments appreciated. Sergei.

Upgrade cluster + adding nodes
by Davide Ferrari 16 Jan '17

16 Jan '17

Hello everyone currently I've a 4-nodes oVirt 4.0.4 cluster running on CentOS 7.2. Given that we have now oVirt 4.0.6 and CentOS 7.3, what's the best update path? I was reading threads about qemu-kvm-ev 2.6 when CentOS 7.3 was released but I was wondering if with 4.0.6 release something has changed. Moreover, I'd like to add 4 more nodes in the near future, I guess I should have all the same version and thus I must fully upgrade the original 4 nodes (both OS + oVirt) before adding new, fully up-to-date nodes, right? Thanks! -- Davide Ferrari Senior Systems Engineer

Hi, I have three glusterfs storage domains present on my system. data (master), vmstore and engine. I tried moving the master storage domain to maintenance state , it was stuck in preparing for maintenance for a long time and then i rebooted my hosts. Now i see that the master domain moves to maintenance state but vmstore which is master now is stuck in locked state. Any idea how to come out of this situation. Any help is much appreciated.

VDSM service won't start
by paul.greene.va 16 Jan '17

16 Jan '17

All, I'm having an issue with the vdsmd service refusing to start on a fresh install of RHEL 7.2, RHEV version 4.0. It initially came up correctly, and the command "ip a" showed a "vdsmdummy" interface and a "ovirtmgmt" interface. However after a couple of reboots, those interfaces disappeared, and running "systemctl status vdsmd" generated the message "Dependency failed for Virtual Desktop Service Manager/Job vdsmd.service/start failed with result 'dependency'". Didn't say what dependency though I have 3 hosts where this happening on 2 out of 3 hosts. For some odd reason, the one host isn't having any problems. In a Google search I found an instance where system clock timing was out of sync, and that messed it up. I checked all three hosts, as well as the RHEV manager and they all had chronyd running and the clocks appeared to be in sync. After a reboot the virtual interfaces usually initially come up, but go down again within a few minutes. Running journalctl -xe gives these three messages: "failed to start Virtual Desktop Server Manager network restoration" "Dependency failed for Virtual Desktop Server Manager" (but it doesn't say which dependency failed" "Dependency failed for MOM instance configured for VDSM purposes" (again, doesn't way which dependency) Any suggestions?

Reminder: we have Wildfly's web mgmt console (with auth)
by Roy Golan 16 Jan '17

16 Jan '17

For quite some time now we can access Wildfly's web console on https://127.0.0.1:8706 It's the UI equivalent of jboss.cli but much more convenient. Example of tasks you can perform there: - Change logging settings, live - Tweak the managed thread pool (will send a different thread about it) - Shutdown/reload the service - Tweak db connection details - Get info/stats on the running setup EE components and more One of the main advantages over the old jmx method is that it uses a plugin to authenticate the engine user so your credentials should be admin@internal or any superuser for that matter. The default is to expose it to localhost and that could be change in services/ovirt-engine/ovirt-engine.xml.in.For firewalled setups, you can ssh tunnel your machine to overcome that as always. R
