It is more friendly for less savvy users and focuses on install information. No confusing Dev talk. But, I would also be fine updating the feature pages with more friendly install instructions if that would be better.

using ovirt-shell to attach defind network to hosts
by Vladimir Pakhomov 05 Oct '14

05 Oct '14

Hi, I would like to implement a script that would attach a newly created network to all hosts in cluster. Unfortunately I cannot find anything about that in documentation. Is it possible to attach network to host using CLI/REST API? Kind regards, Vladimir Pakhomov

API -- Do I need to use templates? Can I change network for the nic?
by Morgan McLean 05 Oct '14

05 Oct '14

Hi, Trying to remotely spawn a large amount of VM's. It would appear I can only use templates...which would have a NIC stuck to one network vlan. It doesn't appear that I can change that vlan remotely. Is there any easy way I can get this done? Thanks, Morgan

Falsely detected network device status
by Lewis Shobbrook 05 Oct '14

05 Oct '14

Hi All, I've encountered a network device that is being falsely detected as down. On adding a new network to a 3.4 hosted engine, one of the two hosts is displaying a component interface as down with the webadmin console. Ethtool confirms the link status as up and connectivity through the corresponding interfaces of the network has been proven. Shortly after adding the network I noted that the node with the falsely detected iface status, was set Non-Operational. All running VM's evacuated. The engine.log showing... INFO [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-33) [2daa7788] Correlation ID: null, Call Stack: null, Custom Event ID: -1, Message: Host hosted_engine_2 moved to Non-Operational state because interfaces 'eth1' are down but are needed by networks 'EVD_DMZ' in the current cluster 2 other interfaces for ovirtmgmt and another VM network on this same host have long functioned perfectly well. When assigning the network to the interface I see the following in messages... Oct 1 20:57:39 lx004 kernel: ADDRCONF(NETDEV_UP): eth1: link is not ready Oct 1 20:57:39 lx004 kernel: 8021q: adding VLAN 0 to HW filter on device eth1 Oct 1 20:57:39 lx004 kernel: device eth1 entered promiscuous mode Oct 1 20:57:40 lx004 kernel: igb: eth1 NIC Link is Up 100 Mbps Full Duplex, Flow Control: RX Oct 1 20:57:40 lx004 kernel: ADDRCONF(NETDEV_CHANGE): eth1: link becomes ready Oct 1 20:57:40 lx004 kernel: EVD_DMZ: port 1(eth1) entering forwarding state Looks as it should to me, brctl also shows the bridge is as it should be. # brctl show bridge name bridge id STP enabled interfaces ;vdsmdummy; 8000.000000000000 no EVD_DMZ 8000.0025901abc49 no eth1 PXE 8000.0007e9a5a197 no eth3 ovirtmgmt 8000.0025901abc48 no eth0 Not able to see anything relevant in vdsm.log vdsClient -s 0 getVdsStats does not list the new network, but instead lists an older deleted one. Has any one encountered an event like this or have any clues on how this might be failing?

oVirt user portal to pass environment variable to vm
by Pat Pierson 05 Oct '14

05 Oct '14

Is there a way to pass oVirt user login details(name) to the vm in the form of an environment variable to the vm? Would that be something Cloud-init or Ovirt-guest-agent handles? -- Patrick Pierson

[OT] A little of oVirt in my i9100 Beanstalk 4.4.4 ROM...
by Gianluca Cecchi 05 Oct '14

05 Oct '14

... as I used an Ubuntu 14.04.1 VM on oVirt 3.5 rc3 infra as the base to build Android Kitkat based Beanstalk ROM for Samsung S2 (i9100): https://plus.google.com/photos/105661760401324958761/albums/606642855573464… BeanStalk-4.4.4065-20141004-i9100.zip https://drive.google.com/file/d/0BwoPbcrMv8mvV0pILWNNUWNkSU0/view?usp=shari… MD5SUM: b3f69a53eac6788dd364c37202826840 It was also an opportunity to successfully test on iSCSI storage domain the online disk/fs resize feature for a running VM as 100Gb of disk space were needed and only 50Gb were initially provisioned ;-) NOTE: I had to repartition my internal sd card because neither pa- gapps mini nor micro would have fit in default 512Mb. I followed link below (valid only for 16Gb i9100 models) using pit file that splits in 1Gb/6Gb/remaining http://forum.xda-developers.com/galaxy-s2/development-derivatives/mod-parti… As seen in other links' disclaimer #include <https://plus.google.com/s/%23include> /* * Your warranty is now not void. * * I am not responsible for bricked devices, dead SD cards, * black cats on your way ahead, divorces. * Please do some research if you have any concerns about features * included in this ROM before flashing it! */ Have a nice Sunday !

[New Documentation] oVirt User Guide (Please Review!)
by Brian Proffitt 03 Oct '14

03 Oct '14

I would like to announce the posting of a new page on the oVirt site: the oVirt User Guide[1]. I know what you're thinking: didn't we just release the oVirt Administration Guide? Why, indeed we did[2]! But this was a shorter document, and so did not take as long to convert. This guide, adapted to MediaWiki form with the help of Red Hat's Content Services team, should be up to date as of oVirt 3.4. But, it is a living document and, like the Administration Guide, it needs further review! I ask everyone to take start poking at this documentation once oVirt 3.5 is released and people get familiar with the new release, so as to identify procedures that have changed, and new features that must be added. Please use Bugzilla to assign bugs in these document to me, or, if you have wiki privileges, edit as needed. Up next: a revised Quick Start Guide to get people launched into oVirt as fast as possible.

Getting Started with oVirt
by Saloni Baweja 03 Oct '14

03 Oct '14

I am an aspirant for OPW and found oVirt interesting. But, I don't know much about virtualized networks, storage etc and am just a beginner. It would be great if I get guidance about how to start understanding about oVirt, what exactly is oVirt. How can I get acquainted with oVirt and understand its code, working ( as a mere beginner ) so that I can start contributing towards this ? -- Build your own dreams, or someone else will hire you to build theirs. ;) Saloni Baweja Blog: salonibaweja10.wordpress.com/
