This is a multi-part message in MIME format. --------------7A7A94A488D7D26C7D1B2EB5 Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: 7bit Hello. Yesterday I had a pretty strange problem in one of our architectures. My oVirt which runs in one Datacenter and controls Nodes locally and also remotelly lost communication with the remote Nodes in another Datacenter. To this point nothing wrong as the Nodes can continue working as expected and running their Virtual Machines each without dependency of the oVirt Engine. What happened at some point is that when the communication between Engine and Hosts came back Hosts got confused and initiated a Live Migration of ALL VMs from one of the other. I had also to restart vdsmd agent on all Hosts in order to get sanity my environment. What adds up even more strangeness to this scenario is that one of the Hosts affected doesn't belong to the same Cluster as the others and had to have the vdsmd restarted. I understand the Hosts can survive without the Engine online with reduced possibilities but can communicated between them, but without affecting the VMs or even needing to do what happened in this scenario. Am I wrong on any of the assumptions ?

Here is a way to filtering a group of ldap user by one of custom attribute and not by groups ? By example, I tryed (without success) to put this entry in /etc/ovirt-engine/extensions.d/my-ldap-authz.properties : search.simple-resolve-groups-memberOf.search-request.filter = &(myCustomAttribute=nameOfAttributeToFilter) And if it's possible, can I have filtering with more than one attribute (i.e.: each attribute will be discriminate like a group) ?

VM with attached host USB device failed to run
by Дровалев Роман 16 Aug '17

16 Aug '17

Hello, I connected a USB to the VM, writes this error: VM Win2012 is down with error. Exit message: local variable 'device' referenced before assignment. I found this bug - https://bugzilla.redhat.com/show_bug.cgi?id=1261075 Does anyone have a working USB forwarding in a virtual machine? If "YES", how did you solve this problem? If this problem is not solved, unfortunately, the ovirt will have to completely abandon. ((

Hosted-engine is not migrate to other hosts
by Spickiy Nikita 15 Aug '17

Hi, in advance sorry, i beginner. I try setting HA on oVirt. I install hosted-engine on host and after adding two hosts in web portal. When i install hosts then select DEPLOY in hosted-engine. But when i shutdown node, on which run hosted-engine, and hosted-engine is not start on other hosts automaticlly. I guess that trouble in state host(he is state=EngineDown), but not found information how to fix it. Maybe it do because i don't setting power management? My configuration: --== Host 1 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : vnode10 Host ID : 1 Engine status : {"health": "good", "vm": "up", "detail": "up"} Score : 3400 stopped : False Local maintenance : False crc32 : 68e523f8 local_conf_timestamp : 178768 Host timestamp : 178753 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=178753 (Mon Aug 14 15:22:49 2017) host-id=1 score=3400 vm_conf_refresh_time=178768 (Mon Aug 14 15:23:04 2017) conf_on_shared_storage=True maintenance=False state=EngineUp stopped=False --== Host 2 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : vnode11 Host ID : 2 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 1204d5c0 local_conf_timestamp : 9290 Host timestamp : 9274 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=9274 (Mon Aug 14 15:22:53 2017) host-id=2 score=3400 vm_conf_refresh_time=9290 (Mon Aug 14 15:23:10 2017) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False --== Host 3 status ==-- conf_on_shared_storage : True Status up-to-date : True Hostname : vnode13 Host ID : 3 Engine status : {"reason": "vm not running on this host", "health": "bad", "vm": "down", "detail": "unknown"} Score : 3400 stopped : False Local maintenance : False crc32 : 14e97435 local_conf_timestamp : 188749 Host timestamp : 188732 Extra metadata (valid at timestamp): metadata_parse_version=1 metadata_feature_version=1 timestamp=188732 (Mon Aug 14 15:22:55 2017) host-id=3 score=3400 vm_conf_refresh_time=188749 (Mon Aug 14 15:23:11 2017) conf_on_shared_storage=True maintenance=False state=EngineDown stopped=False Thank you in advance!
