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.
