Re: [ovirt-users] How to import a qcow2 disk into ovirt

by Martín Follonier

Hi, I've done all the recommendations in this thread, and I'm still getting the "Paused by System" message just after the transfer starts. Honestly I don't know were else to look at, cause I don't find any log entry or packet capture that give me a hint about what is happening. I'll appreciate any help! Thank you in advance!

I tried a qcow2 disck configured as 40Gb but containing about 1.6Gb of data. I'm going to connect it to a VM and see if all is ok also from a contents point of view.

Lowering the bar for wiki contribution?

by Roy Golan

I'm getting the feeling I'm not alone in this, authoring and publishing a wiki page isn't as used to be for long time. I want to suggest a bit lighter workflow: 1. Everyone can merge their page - (it's a wiki) Same as with (public and open) code, no one has the motivation to publish a badly written wiki page under their name. True, it can have an impact, but not as with broken code 2. Use Page-Status marker The author first merges the draft. Its now out there and should be updated as time goes and its status is DRAFT. Maintainers will come later and after review would change the status to PUBLISH. That could be a header in on the page: --- page status: DRAFT/PUBLISH --- Simple I think, and should work.

ovirt-ha-agent cpu usage

by Gianluca Cecchi

Hello, I have a test machine that is a nuc6 with an i5 and 32G of ram and SSD disks. It is configured as a single host environment with Self Hosted Engine VM. Both host and SHE are CentOS 7.2 and oVirt version is 3.6.6.2-1.el7 I notice that having 3 VMs powered on and making nothing special (engine VM, a CentOS 7 VM and a Fedora 24 VM) the ovirt-ha-agent process on host often spikes its cpu usage. See for example this quick video with top command running on host that reflects what happens continuously. https://drive.google.com/file/d/0BwoPbcrMv8mvYUVRMFlLVmxRdXM/view?usp=sha... Is it normal that ovirt-ha-agent consumes all this amount of cpu? Going into /var/log/ovirt-hosted-engine-ha/agent.log I see nothing special, only messages of type "INFO". The same for broker.log Thanks, Gianluca

Hosted engine Single Sign-On to VM with freeIPA not working

by Paul

This is a multipart message in MIME format. ------=_NextPart_000_0050_01D18069.35C995E0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Hi, I am having an issue with getting SSO to work when a standard user(UserRole) logs in to the UserPortal. The user has permission to use only this VM, so after login the console is automatically opened for that VM. Problem is that it doesn't login on the VM system with the provided credentials. Manual login at the console works without any issues. HBAC-rule check on IPA shows access is granted. Client has SELINUX in permissive mode and a disabled firewalld. On the client side I do see some PAM related errors in the logs (see details below). Extensive Google search on error 17 "Failure setting user credentials" didn't show helpful information :-( AFAIK this is did a pretty standard set-up, all working with RH-family products. I would expect others to encounter this issue as well. If someone knows any solution or has some directions to fix this it would be greatly appreciated. Thanks, Paul ------------------------------------------------------ System setup: I have 3 systems The connection between the Engine and IPA is working fine.

VM has been paused due to storage I/O problem

by Gianluca Cecchi

Hello, my test environment is composed by 2 old HP blades BL685c G1 (ovmsrv05 and ovmsrv06) and they are connected in a SAN with FC-switches to an old IBM DS4700 storage array. Apart from being old, they seem all ok from an hw point of view. I have configured oVirt 4.0.6 and an FCP storage domain. The hosts are plain CentOS 7.3 servers fully updated. It is not an hosted engine environment: the manager is a vm outside of the cluster. I have configured power mgmt on both and it works good. I have at the moment only one VM for test and it is doing quite nothing. Starting point: ovmsrv05 is in maintenance (since about 2 days) and the VM is running on ovmsrv06. I update qemu-kvm package on ovmsrv05 and then I restart it from web admin gui: Power Mgmt --> Restart Sequence of events in pane and the problem in subject: Jan 31, 2017 10:29:43 AM Host ovmsrv05 power management was verified successfully.

Watching the timestamps, the culprit seems the reboot time of ovmsrv05 that detects some LUNs in owned state and other ones in unowned Full messages of both hosts here: https://drive.google.com/file/d/0BwoPbcrMv8mvekZQT1pjc0NMRlU/view?usp=sha... and https://drive.google.com/file/d/0BwoPbcrMv8mvcjBCYVdFZWdXTms/view?usp=sha... At this time there are 4 LUNs globally seen by the two hosts but only 1 of them is currently configured as the only storage domain in oVirt cluster.

Changing gateway ping address

by Matteo

Hi all, I need to change the gateway ping address, the one used by hosted engine setup. Is ok to edit /etc/ovirt-hosted-engine/hosted-engine.conf on each node, update the gateway param with the new ip address and restart the agent&broker on each node? With a blind test seems ok, but need to understand if is the right procedure. Thanks, Matteo

ovirt 4 reboot behaviour

by Giulio Casella

Hi, I noticed a different behaviour after upgrading my entire setup from rhev 3.6.9 to rhev 4.0.5. A virtual machine reboot changes the host where the VM is running, also if the VM was started in "run once" mode with a payload specifying a placement policy. In version 3 the VM didn't change host across a reboot; and continued running in run once mode, keeping the same payload given at start time. Is there a way to keep the VM running on the same host across a reboot, excluding the obvious (but time consuming) way of migration after reboot? If not (but this is a request for enhancement), is it possible to introduce a payload for reboot (just like for "start") to specify the placement policy? Thank you in advance, gc
