hosted engine , how to make changes to the VM post deploy
by Alastair Neil 17 Nov '14

17 Nov '14

I have successfully migrated my standalone ovirt into a hosted instance. I have some questions and comments. Is there a mechanism to make changes to the hosted engine VM post deploy. I would like to change some of the VM configuration choices. I tried setting the maintenance mode to "global" and then editing: /etc/ovirt-hosted-engine/vm.conf I changed something simple: the VM name. Then I copied the file to the two other HA hosts and set the maintenance mode to "none". No joy the VM hostname remains unchanged in the portal. Also, the notification system is horrendously spammy, I get email notification of each state change from each of the HA hosts, surely this is not intentional. Is there some way to control this? -Thanks, Alastair

Latest ovirt-node release/installation
by Christopher Young 17 Nov '14

17 Nov '14

I sincerely hope that this is not answered elsewhere as I've done several searches and have yet to find a solid answer. I have three (what I believe to be) basic questions (with perhaps some subs there): 1) What is the latest oVirt-node release and where would one download it (I appear to only see 3.4 -based releases of the ISO available)? It is 3.5-based and/or is there an upgrade path? Which glusterfs release is currently included with oVirt-node? 2) As I understand it, newer releases of oVirt-node allow you to do an installation of the self-hosted engine at this time. Is that correct? 3) Is there any functionality that one would be losing out on by deploying oVirt via oVirt-node vs. using full-OS installation? Which is the more recommended? Again, I apologize if these questions are covered somewhere, but I felt like asking them in a direct fashion so as to clear up my own ignorance. I appreciate any feedback and information that you could share. Thanks, Chris

Migrating from Fedora 19 to Fedora 20 with oVirt 3.5.0
by Sandro Bonazzola 16 Nov '14

16 Nov '14

Hi, just finished testing migration path from F19 to F20 for systems running oVirt. F19 is going EOL one month after F21 release which is currently planned for December 2nd. If you're running oVirt on Fedora 19 I suggest you to do it once finished to upgrade oVirt to 3.5.0. I've saved some notes in the test request bug[1]: Bug 1131828 - Test upgrade path from Fedora 19 with oVirt 3.5.z to Fedora 20 Enjoy!

Hi: I have my VDSM service and engine up and running now am trying to create a VM. As my client machine is Windows 8.1 Pro I am trying to use noVNC to connect. Am not using a self signed SSL cert but every time I try and connect it says "connect timeout". Port on the engine is listening fine: tcp 0 0 0.0.0.0:6100 0.0.0.0:* LISTEN 1964/python What could I be doing wrong please ? Thanks, Phil

Network rules
by Jürgen Brandl 16 Nov '14

16 Nov '14

Hello, I'm new, so forgive me if this is stupid or in the wrong place. Because of security reasons, I want a network, where my VMs can talk to one single VM (eg. proxy or management), but not with each other or the host machine. Is there a simple way to solve this, without creating dozens of networks? Jürgen

oVirt Node 3.5 build available for testing
by Fabian Deutsch 14 Nov '14

14 Nov '14

Hey, finally we reached a stage again where we can provide an oVirt Node. The following oVirt Node ISO contains the oVirt 3.5.0 packages. Please go ahead, test it and provide feedback in case of issues. https://fedorapeople.org/~fabiand/node/3.5/ovirt-node-iso-3.5.0.ovirt35.201… To learn something more about oVirt Node please visit http://www.ovirt.org/Node http://www.ovirt.org/Quick_Start_Guide#Install_oVirt_Node Please note that this is still an pre-release, and we are aware that there are still issues with the hosted-engine part of Node. But this part will see some (already pending updates) in the near future. Greetings fabian

Live merge?
by Martijn Grendelman 14 Nov '14

14 Nov '14

Hello, The first thing the 3.5 release notes talk about is Live Merge of snapshots and I've been dying to try that out. Problem: I think my environment is completely up to date now, but the "Delete" link on VM snapshots remains greyed out when the VM is running. Going via "Storage" -> Domain name -> "Disk Snapshots", clicking "Remove" is possible (UX inconsistency), but it stops with "Error while executing action: Cannot remove Disk Snapshot. At least one of the VMs is not down." What is needed, besides the following, to make live merge work? - oVirt Engine Version: 3.5.0.1-1.el6 - Data Center Compatibility Version: 3.5 - Host OS: RHEL - 6 - 6.el6.centos.12.2 - KVM Version: 0.12.1.2 - 2.415.el6_5.7 - Libvirt Version: libvirt-0.10.2-46.el6_6.1 - VDSM version: vdsm-4.16.7-1.gitdb83943.el6 - Live Snapsnot Support: Active VM has been restarted to make sure it's running on the latest qemu-kvm. Please advise, thank you in advance. Best regards, Martijn Grendelman

Error trying to add new hosted-engine host to upgraded oVirt cluster
by David King 13 Nov '14

13 Nov '14

Hi everyone, I have upgraded my oVirt 3.4 hosted engine cluster to oVirt 3.5 using the upgrade instructions on the Wiki. Everything appears to be working fine after the upgrade. However, I am now trying to add a new host to the hosted engine configuration but the hosted-engine --deploy fails after sshing the answers file from the upgraded primary configuration. The following errors can be found in the setup log: Answer file lacks lockspace UUIDs, please use an answer file generated from > the same version you are using on this additional host I confirmed that the answers file on the upgraded host does not have any lockspace UUIDs: OVEHOSTED_STORAGE/storageDatacenterName=str:hosted_datacenter > OVEHOSTED_STORAGE/storageDomainName=str:hosted_storage > OVEHOSTED_STORAGE/storageType=none:None > OVEHOSTED_STORAGE/volUUID=str:da160775-07fe-4569-b45f-03be0c5896a5 > OVEHOSTED_STORAGE/domainType=str:nfs3 > OVEHOSTED_STORAGE/imgSizeGB=str:25 > OVEHOSTED_STORAGE/storageDomainConnection=str:192.168.8.12: > /mnt/data2/vm/engine > OVEHOSTED_STORAGE/connectionUUID=str:880093ea-b0c1-448d-ac55-cde99feebc23 > OVEHOSTED_STORAGE/spUUID=str:5e7ff7c2-6e75-4ba8-a5cc-e8dc5d37e478 > OVEHOSTED_STORAGE/imgUUID=str:c9466bb6-a78c-4caa-bce3-22c87a5f3f1a > OVEHOSTED_STORAGE/sdUUID=str:b12fd59c-380a-40b3-b7f2-02d455de1d3b Is there something I can do to update the answers file on the updated 3.5 working host so this will work?

[VOTE NEEDED] oVirt meetings schedule change proposal
by Sandro Bonazzola 13 Nov '14

13 Nov '14

Hi, last oVirt sync meeting was skipped and the previous one was at risk due to a bit of confusion on DST changes. oVirt sync meeting is the only meeting we have bound to UTC without DST changes. Current scheduled meeting list is available here: http://www.ovirt.org/Meetings#Meeting_Time_and_Place We don't have a reference timezone, we use: UTC, EDT, Asia/Jerusalem. The UTC time zone has been deemed obsolete. It has been replaced by Etc/UTC and it doesn't use DST. EDT is currently not observed in North America since DST isn't active. Locations are currently observing EST instead. Asia/Jerusalem is following DST changes. I suggest to unify the reference timezone. Since it seems that using UTC causes issues in re-scheduling other local timezone tasks, I guess best solution is to follow the DST changes. As nearest to UTC following DST I suggest Europe/London as timezone. Comments are welcome. -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration.

Re: [ovirt-users] hosted engine on iSCSI deep dive
by jplorier＠gmail.com 13 Nov '14

Hi, First thanks for the video. Though I have a question about the setup. I don't see any options regarding multipath. You are connecting directly to the iscsi lun, but most of the times the connection is redundant and multipathd needs to be configured in order to have redundancy. Is it a future enhancement or multipath is done behind scene? If it's taking care of it, what about special configs for the device in the multipath.conf? Regards
