[ovirt-users] oVirt 3.5.0 Second Alpha postponed due to jenkins issues

In order to allow basic sanity testing before releasing second alpha, its release has been postponed to tomorrow. Thanks, -- Sandro Bonazzola Better technology. Faster innovation.

The security group is configured per VM, the rules are configured by the system on the node the VM is running on. From the user perspective you need to configure a security group policy and then associate the VM with the relevant policy, there is also a default policy to which all VMs are associated by default. To use this feature you need to use the oVirt-Neutron integration - http://www.ovirt.org/Features/Detailed_OSN_Integration#Security_groups One caveat in this integration is that we did not handle VM migration yet.

Re: [ovirt-users] experience with AMD Kabini (Jaguar) CPUs
Hi Doron, I haven't purchased the Kabini-based system. I hoping that I would be able to learn in advance whether an all-in-one installation of oVirt would work on it. Unfortunately, returning it would be a hassle and I would not get a full refund for it. If there is no way to discover in advance whether oVirt will work on the system, I can take a risk.

I am not sure if they are related or not. 1. The NFS timeout during shutdown (Joop do you see this also? Or just #2?) 2. The system reboot instead of poweroff (which messes up remote machine management) For 1. I was wondering if perhaps, we could have an option to specify the mount options. If I understand correctly, applying a soft mount instead of a hard mount would prevent this from happening. I'm however not sure of the implications this would have on the data integrity.. I would really like to see it happen in the ha-agent, as it's the one which connects/mounts the storage it should also unmount it on boot. However the stability on it, is flaky at best. I've noticed if `df` hangs because of another NFS mount having timed-out the agent will die. That's not a good sign.. this was what actually caused my hosted-engine to run twice in one case. Thanks, Bob I think wdmd or sanlock are causing the reboot instead of poweroff Joop Great to have your feedback guys! So just to clarify some of the issues you mentioned; Hosted engine wasn't designed for a 'single node' use case, as we do want it to be highly available. This is why it's being restarted elsewhere or even on the same server if no better alternative. Having said that, it is possible to set global maintenance mode as a first step (in the UI: right click engine vm and choose ha-maintenance). Then you can ssh into the engine vm and init 0. After a short while, the qemu process should gracefully end and release its sanlock lease as well as any other resource, which means you can reboot your hypervisor peacefully. Sadly no, I've only been able to reboot my hypervisors if one of the two conditions are met: - Lazy unmount of /rhev/mnt/hosted-engine etc. - killall -9 sanlock wdmd I notice sanlock and wdmd are not able to be stopped with service wdmd stop; service sanlock stop These seem to fail during the shutdown/reboot process which prevents the unmount and the graceful reboot. Are there any logs I can look into on how to debug those failed shutdowns? Doron ___ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users

Re: [ovirt-users] VM HostedEngie is down. Exist message: internal error Failed to acquire lock error -243
Hi Andrew, this is something that I saw in my logs too, first on one node and then on the other three. When that happend on all four of them, engine was corrupted beyond repair. First of all, I think that message is saying that sanlock can't get a lock on the shared storage that you defined for the hostedengine during installation. I got this error when I've tried to manually migrate the hosted engine. There is an unresolved bug there and I think it's related to this one: [*Bug 1093366* https://bugzilla.redhat.com/show_bug.cgi?id=1093366 -Migration of hosted-engine vm put target host score to zero] https://bugzilla.redhat.com/show_bug.cgi?id=1093366 This is a blocker bug (or should be) for the selfhostedengine and, from my own experience with it, shouldn't be used in the production enviroment (not untill it's fixed). Nothing that I've done couldn't fix the fact that the score for the target node was Zero, tried to reinstall the node, reboot the node, restarted several services, tailed a tons of logs etc but to no avail. When only one node was left (that was actually running the hosted engine), I brought the engine's vm down gracefully (hosted-engine --vm-shutdown I belive) and after that, when I've tried to start the vm - it wouldn't load. Running VNC showed that the filesystem inside the vm was corrupted and when I ran fsck and finally started up - it was too badly damaged. I succeded to start the engine itself (after repairing postgresql service that wouldn't want to start) but the database was damaged enough and acted pretty weird (showed that storage domains were down but the vm's were running fine etc). Lucky me, I had already exported all of the VM's on the first sign of trouble and then installed ovirt-engine on the dedicated server and attached the export domain. So while really a usefull feature, and it's working (for the most part ie, automatic migration works), manually migrating VM with the hosted-engine will lead to troubles. I hope that my experience with it, will be of use to you. It happened to me two weeks ago, ovirt-engine was current (3.4.1) and there was no fix available.

Exit message: internal error Failed to acquire lock: error -243. It also appears to occur on the other hosts in the cluster, except the host which is running the hosted-engine. So right now 3 servers, it shows up twice in the engine UI. The engine VM continues to run peacefully, without any issues on the host which doesn't have that error.

Perhaps someone made a youtube video of the install. I saw some prior posts where other were having issues but when they asked for helped they got the old RTFM answer. The problem is the FM seems to be missing some steps. Any help would be appreciated. Thanks You mean this[1] FM?
