Guest OS wrong cpu count
by Johan Kooijman 03 Mar '16

03 Mar '16

Hi all, I created a VM on our ovirt 3.5 cluster having 8 CPU's and 16 GB of RAM ( http://imgur.com/aaXfbfq) The guest however, only sees 4 CPU's: http://imgur.com/dEYVe0S. Any clues what may have caused this? -- Met vriendelijke groeten / With kind regards, Johan Kooijman

VMs Pause During Live Snapshot Creation
by Duckworth, Douglas C 02 Mar '16

02 Mar '16

It is my understanding that VMs must pause during Live Snapshot creation when "Save Memory" option is selected. If you're only seeking to mitigate against issues that might arise after doing package updates then what's the advantage of going with that route? Down the road does anyone know if it will be possible for oVirt and eventually RHEV to gather snapshots without Pausing VMs? Does Docker make this a feature we likely won't see developed? -- Thanks Douglas Duckworth, MSc, LFCS Unix Administrator Tulane University Technology Services 1555 Poydras Ave NOLA -- 70112 E: duckd(a)tulane.edu O: 504-988-9341 F: 504-988-8505

[ANN] oVirt 3.6.3 Final Release is now available
by Sandro Bonazzola 01 Mar '16

01 Mar '16

The oVirt Project is pleased to announce today the general availability of oVirt 3.6.3. This latest community release includes numerous bug fixes and several new features, such as: - The WebSocketProxy VDC option(and a few others) can now be updated without need to restart the engine. - OVIRT-CLI now use remote-viewer instead of spicec for spice based console - unassigned host status now reflects more the real status - cloud-init service after appliance deployment is now disabled oVirt is an open-source, openly-governed enterprise virtualization management application, developed by a global community. You can use the oVirt management interface (oVirt Engine) to manage hardware nodes, storage and network resources, and to deploy and monitor virtual machines running in your data center. If you are familiar with VMware products, oVirt is conceptually similar to vSphere. oVirt serves as the bedrock for Red Hat's Enterprise Virtualization product, and it is the "upstream" project where new features are developed prior to their inclusion in Red Hat's supported product offering.

Not seeing Gluster options on Cluster properties
by Will Dennis 01 Mar '16

01 Mar '16

Hi all, I am running a hyperconverged setup of oVirt 3.6, where I pre-made the Gluster volumes that are used for the hosted engine and the VM storage domains. I have seen in screenshots of 3.6 HC setups that there should be options to enable Gluster integration in oVirt by checking a box in Cluster properties > General tab (“Enable Gluster Service”) but I do not see that checkbox in my Cluster properties > General tab. What must I do to enable this integration? BTW, I see that there is a package "vdsm-gluster-4.17.18-0.el7.centos.noarch” installed on all of my oVirt nodes… Is there another package that I am missing? Thanks, Will

virt-v2v converting multi-disk
by Clint Boggio 01 Mar '16

01 Mar '16

I'm in the process of migrating a series of VM's from KVM environment, to an OVirt environment. I've used virt-v2v to convert quite a few M$ and Linux machines with great success. Coming up I've got to convert a Linux VM that has 3 virtual disks. Inside that VM, the three disks are part of an LVM volume. 1. How will virt-v2v handle these three virtual disks ? 2. On which disk image will I run virt-v2v ? 3. Will virt-v2v "follow" the three images and convert the machine or will I have to somehow tell it to include all three disks ? 4. Shall I have all three images together in the same directory when I run the tool ? 5. Is this the appropriate forum for this question ? As of the writing of this question I'll be using OVirt 3.6 updated on a 4 node cluster running CentOS 7 , and the most recent version of virt-v2v as is available on Fedora 23.

oVirt New Install
by Brett I. Holcomb 01 Mar '16

01 Mar '16

I am in the process of testing oVirt to replace ESXi 6 and have run into some issues that I haven't found answers to. I've used ESXi for quite a while and done some work with Microsoft's Hypervisor but am new to oVirt. It looks like it has potential to replace the others but there are some major issues I'm trying to work through. I'm using a hosted-engine deployment. The host is a guest on VMware Workstation 11 on Windows. Not the best but it lets me test oVirt. I've created the VM, the engine is installed, the webadmin works, and I can SSH to it but I'm seeing some things that I haven't been able to find answers to so any help is appreciated. I'm using DNS to resolve and both the engine and host can ping each other, reverse lookup on their names works. 1. I used an iSCSI LUN on a NAS for storage during the deploy install but this storage does not show up in the admin portal list of storages. Is it supposed to? It's being used as it now has 3+ our of 50 gig used. 2. I used a local directory on the VM for an initial ISO domain but it does not show up in the admin portal. I have more than 15 Gig of space available. Shouldn't it be showing up in the list of storages? I tested using this (http://www.ovirt.org/documentation/how-to/troublesho oting/troubleshooting-nfs-storage-issues/) and from the host I can mount the engine's exported directory and create a file in it as the vdsm user. 3. My host wants confirmation it's rebooted which it has been both with hosted-engine vm-shutdown/vm-start, and rebooting from within the engine. If I tell it to confirm I get the message below. Well, it's status is running. i can't connect when it's connecting or non- operational!! I've put the system into maintenance mode with hosted- engine commands, I used the context menu on the hosted-engine vm in the portal to put it into maintenance but it still refuses to confirm it's rebooted. Any ideas on how to get it confirmed. I've also rebooted the hosted-engine host with no change. "Error while executing action: Cannot confirm 'Host has been rebooted' Host. Valid Host statuses are "Non operational", "Maintenance" or "Connecting"." 4. My Default Data Center is uninitialized which is probably why nothing works. If I use guide me and attach the hosted_engine choice it tells me it cannot acquire a host id. I restarted the sanlock service and then when I attached the storage the dialog hung up spinning it's wheel and never returned. I restarted the VM from hosted-engine and still get the AcquireHostId failure. The iSCSI lun is being used and accessed by the engine as there is 3+ gig of space used. If I try and attach the hosted_engine storage the icon changes to a wrench, then back to the red down arrow and I get the error about not acquiring a host id. What host id? I only have one host! I've reinitialized the lockspace all with no effect. The /var/log/ovirt- engine/engine.log has this error. What invalid argument? I've seen some bug reports on this but they are back in version 3.3 or so and are supposed to be fixed. Command 'org.ovirt.engine.core.bll.storage.AddStoragePoolWithStoragesCommand' f ailed: EngineException: org.ovirt.engine.core.vdsbroker.vdsbroker.VDSErrorException: VDSGenericExcep tion: VDSErrorException: Failed to CreateStoragePoolVDS, error = Cannot acquire host id: ('1d26d977- 0a67-43ab-bfb8-462cea95029a', SanlockException(22, 'Sanlock lockspace add failure', 'Invalid argumen t')), code = 661 (Failed with error AcquireHostIdFailure and code 661) Any help is appreciated. Thanks.

macvlan + IPv6
by Jay Turner 29 Feb '16

29 Feb '16

Hoping someone can help with a problem my team is seeing under oVirt. We are making heavy use of macvlan interfaces (in VEPA mode) on-top of virtual functions, under VMs being managed by oVirt. In this scenario IPv6 is not playing nicely, with no traffic going through, and messages about neighbor solicitation. There are some pointers out there indicating the issue stems from the fact IPv6 utilizing multicast for neighbor solicitation, but nothing we have tried seems to work around this issue. The problem is made all the most bizarre by the fact that on the same hardware libvirt + virt-manager works perfectly fine. I have looked at the corresponding xml for the guests, and nothing seems to point to the underlying cause for oVirt to fail, but libvirt to succeed. * Intel XL710 40G NICs (i40e/i40evf drivers) * CentOS 7.1 (fully up-to-date) * oVirt 3.6 * libvirt-1.2.17 * virt-manager-1.2.1-8 Thanks for any pointers folks can provide. - jkt

Snapshot Locked for an extended period of time
by Simon Hallam 28 Feb '16

28 Feb '16

Hi All, I’ve recently written a script which: 1. Takes a snapshot with memory. 2. Creates a VM from that snapshot. 3. Exports the snapshot to the export domain. 4. Deletes the snapshot. 5. Deletes the cloned VM. Whilst running the script for the first time last night, the script timed out whilst deleting the snapshot on the VM at step 4. Now the logs are filled with: 2016-02-25 10:32:53,272 INFO [org.ovirt.engine.core.bll.RemoveSnapshotCommandCallback] (DefaultQuartzScheduler_Worker-25) [4559dd29] Waiting on Live Merge child commands to complete 2016-02-25 10:32:53,332 INFO [org.ovirt.engine.core.bll.RemoveSnapshotSingleDiskLiveCommand] (DefaultQuartzScheduler_Worker-25) [225b841f] Waiting on Live Merge command step MERGE to complete 2016-02-25 10:32:53,335 INFO [org.ovirt.engine.core.bll.MergeCommandCallback] (DefaultQuartzScheduler_Worker-25) [4559dd29] Waiting on merge command to complete 2016-02-25 10:32:55,331 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-19) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress (no change) 2016-02-25 10:32:58,405 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-37) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress, updating 2016-02-25 10:33:01,521 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-56) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress (no change) 2016-02-25 10:33:03,337 INFO [org.ovirt.engine.core.bll.RemoveSnapshotCommandCallback] (DefaultQuartzScheduler_Worker-12) [4559dd29] Waiting on Live Merge child commands to complete 2016-02-25 10:33:03,350 INFO [org.ovirt.engine.core.bll.RemoveSnapshotSingleDiskLiveCommand] (DefaultQuartzScheduler_Worker-12) [225b841f] Waiting on Live Merge command step MERGE to complete 2016-02-25 10:33:03,352 INFO [org.ovirt.engine.core.bll.MergeCommandCallback] (DefaultQuartzScheduler_Worker-12) [4559dd29] Waiting on merge command to complete 2016-02-25 10:33:04,678 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-22) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress (no change) 2016-02-25 10:33:07,852 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-11) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress (no change) 2016-02-25 10:33:10,993 INFO [org.ovirt.engine.core.vdsbroker.VdsUpdateRunTimeInfo] (DefaultQuartzScheduler_Worker-44) [4559dd29] VM job c1064551-022f-4549-a9d4-bb915e177e80: In progress, updating 2016-02-25 10:33:13,354 INFO [org.ovirt.engine.core.bll.RemoveSnapshotCommandCallback] (DefaultQuartzScheduler_Worker-14) [4559dd29] Waiting on Live Merge child commands to complete I have attached the log of when the snapshot started deleting (2016-02- 24 23:51:17,094).
