VM migration fails when hardware node fails
by Bill James 11 Dec '15

11 Dec '15

We are testing our new ovirt installation. We notice that if I shutdown a hardware node that the VM's do not migrate off and don't start up after the node is restarted. Its a 3 node cluster with the ovirt-engine on a 4th host. centos 7.1.1503 ovirt-engine-3.6.0.3-1.el7.centos.noarch glusterfs-3.7.5-1.el7.x86_64 High Availability box is checked, Priority = High. 2015-12-10 11:43:34,251 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-8-thread-42) [5f8883ec] Correlation ID: 5d94dbf7, Job ID: 83159d5a-0ab9-4f1b-afbc-e5c2fcbb6e04, Call Stack: null, Custom Event ID: -1, Message: Failed to migrate VM billjov2.test.j2noc.com to Host ovirt3.test.j2noc.com .

Hi list, It could be great if we can follow process like moving Disk storage, snapshots or VM import in the oVirt Interface, like in VMware or VMM. Regards, Kevin C

Strange permissions on Hosted Engine HA Agent log files
by Giuseppe Ragusa 10 Dec '15

10 Dec '15

Hi all, I'm installing oVirt (3.6) in self-hosted mode, hyperconverged with GlusterFS (3.7.6). I'm using the oVirt snapshot generated the night between the 18th and 19th of November, 2015. The (single, at the moment) host and the Engine are both CentOS 7.1 fully up-to-date. After ovirt-hosted-engine-setup successful completion, I found the following (about 3 days after setup completed) "anomalies": 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/agent.log.2015-11-23 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log 666 1 vdsm kvm - /var/log/ovirt-hosted-engine-ha/broker.log.2015-11-23 The listing above comes from a custom security checking script that gives: "octal permissions" "number of links" "owner" "group" - "absolute pathname" Is the ominous "666" mark actually intended/necessary? ;-) Do I need to open a bugzilla notification for this? Many thanks in advance for your attention. Regards, Giuseppe

hot plug memory in el7
by Nathanaël Blanchet 10 Dec '15

10 Dec '15

Hi all, I may miss something but according to http://www.ovirt.org/Features/Hot_Plug_Memory, ovirt 3.6 was supposed to support the hot plug memory feature. Nothing happens in reality when increasing memory on a running vm with centos7. I found this : http://lists.ovirt.orgpipermail/kimchi-devel/2015-June/010714.html, and it seems that el7.1 can't support the feature because of its libvirt version (1.2.8) while the required one is 1.2.14. I didn't test, but I guess F22 supports it. Is there any chance that el7.2 would support it with a backported libvirtd? Or will a dedicated libvirt rhev package be released so as the downstream to support it (like qemu-kvm for live snapshot some time ago)? Documentation and limitation of the libvirt version for hot plug memory are difficult to find in the ovirt wiki and more generally on the web. Maybe the feature has been postponed to a 3.6.z release? Thank you for your help

(Re-adding the list, adding Sandro) The plan for hyper-convergence is to require at least 3 hosts, so that you have a replica-3 cluster storage. Perhaps we should reconsider allowing local storage with hosted-engine. This will prevent HA, but will fit into the place of current allinone usage. The next stage will be that users will ask to migrate this local storage to shared one (or even gluster :-) ). For a 2-cluster HA setup we do not have, or plan to have AFAIK, any official support, but you can have a look at DRBD [1]. [1] http://www.ovirt.org/Features/DRBD Best, -- Didi
