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 17 Nov '14

17 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!

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

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

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

error to run VM
by Halimaton Saadiah 13 Nov '14

13 Nov '14

Hello I am using ovirt-engine version 3.4 , currently having problems to run VM, and get error VM Debian is down. Exit message: child quit during startup handshake: Input/output error. Before this, I manage to run VM Debian then after installation complete , I shut it down and when run it back I unable to run it back as it mentioned the error "cannot run VM low disk space on target storage domain local_storage." I do check my server df -h , yes I have too much space on the root partition where all the ovirt-engine setup was there, but we have more unused space at /home partition, then what I do after that we copy the images(iso file) for that particular vm into the /home partition then rename it according to path stated at the ISO_DOMAIN. By doing all the process I can't manage to run the VM yet and get the error message stated that "VM Debian is down. Exit message: child quit during startup handshake: Input/output error." Is there anyone can help us to solve this problems, or give us the solution that we can figure out on how can we run the VM. Thank you in advance.

oVirt 3.5: Issue with FC Storage on EL7 host
by The Austrian 12 Nov '14

12 Nov '14

Just a heads up I ran into an issue with adding a Fibre Channel storage domain on a CentOS 7 host. vdsm-4.16.7-1.gitdb83943.el7.x86_64 from oVirt 3.5 Release repo This version of vdsm still has the code in /usr/share/vdsm/storage/hba.py that performs issue_lip to rescan fibre channel HBAs. In my setup, the HBA paths are still recovering when 'dmsetup status' is run resulting in paths being offline and the LUNs being made unavailable to oVirt (UI shows exclamation mark). Issue discussed here: https://bugzilla.redhat.com/show_bug.cgi?id=1159839 Quick workaround that worked for me: (1) Comment line 107 in /usr/share/vdsm/storage/multipath.py i.e.: #supervdsm.getProxy().hbaRescan() (2) Restart supervdsmd systemctl restart supervdsmd.service Regards Paul

replace ovirt engine host
by ml ml 12 Nov '14

12 Nov '14

Hello List, currently i am testing backup and restore of my ovirt engine host. So far the backup and recovery works. Since i have a nfs ISO_DOMAIN i need to remount the nfs mounts on my vdsm hosts/nodes. This is kinda ugly but okay :) However, my storage information seems to go weird. It looks like the ovirt engine gets confused about the current status. Do i have to restart vdsm after replacing the ovirt engine? When i put connect my original ovirt engine again the cluster status is okay... I test this by unplugging the original ovirt engine host network cable and doing a restore on a connrected 2nd machine. So i guess my question is: How do i replace my ovirt engine smoothly in a production enviorment? Thanks, Mario

Multiple ISO Storage Domains
by Phil Daws 12 Nov '14

12 Nov '14

Hello: How does one create multiple ISO domains ? if I try it just throws a general error "Error while executing action New NFS Storage Domain: Error creating a storage domain". And if the question is asked why would one require multiple ISO domains its when one has clusters in multiple data centers. Thanks, Phil

USB redirect
by Juan Jose 12 Nov '14

12 Nov '14

Hello everybody, I have an oVirt 3.4 deployment and I have some Windows 7 Enterprise 32 bits guests. I can't redirect USB from a Windows 7 client. I'm using remote - viewer as console. Also I have observed something wrong in my administration portal. The oVirt documentation says that I have to select Native USB mode in console properties in VM configuration but after select this mode, it doesn't remain. If I check this value in console configuration again I can see disabled, native mode value have been changed. Is there someone have had this problem?, and how I can solve it?, is it necessary to install in Windows clients us clerk software? Many thanks in advanced. Juanjo.

Hi, today I've decided to upgrade my 3.4 Ovirt cluster to 3.5/ The engine migration was OK. Everything was good .. after I want upgraded the node .. I've installed the rpm on the node and follow : http://www.ovirt.org/OVirt_3.5_Release_Notes#Install_.2F_Upgrade_from_Previ… . Now my vms cannot be started.

phantom snapshot blocking other operations
by Toby Chappell 11 Nov '14

11 Nov '14

I attempted to make a live snapshot of a Windows VM last night, and got the message "Failed to create live snapshot <name> for VM <vm>. VM restart is recommended". So, I then shut the VM down normally, and attempted to remove the snapshot. I got an error that the snapshot could not be removed because it was still in progress. Looking underneath the covers at the 'images' directory for this VM on the storage filesystem, I don't see any evidence of a snapshot in progress (the *_MERGE* files). The Snapshots tab for the VM does not show any snapshots (other than the 'Active VM' entry). I can't boot the VM however. When attempting to detach the disk and mount it on another Windows VM for inspection, I receive the message "Cannot detach virtual disk. The disk is already configured in a snapshot. In order to detach it, remove the disk's snapshots". How can I convince oVirt there is no snapshot so I can move forward with the rest of resurrecting this important VM? oVirt Engine Version: 3.4.0-1.fc19 (running on Fedora Core 19 server) hosts: running vdsm-4.13.0-11.el6.x86_64 on CentOS 6.5 storage: NFS from an in-house NAS based on ZFS on OpenIndiana Many thanks in advance, Toby -- Toby Chappell, RHCE Director, Enterprise Services Educational Technology Georgia Gwinnett College toby(a)ggc.edu / 678-407-5305

Mask CPU model and mixed clusters
by Mario Giammarco 10 Nov '14

10 Nov '14

Hello, I would like to know if there are improvements regarding ovirt support of mixed clusters (with amd and intel cpus). I see that is a feature supported by kvm because at least pve/proxmox and cloudstack support mixed cluster with migration and ha. Thanks in advance for any reply! Mario
