Scheduled major outage for several centos services and impact on oVirt project
by Simone Tiraboschi 14 Mar '17

14 Mar '17

Hi, as announced and scheduled, several centos services are going to be out of service for about 48 hours since March 14th, 13:00 UTC: https://seven.centos.org/2017/03/infra-scheduled-major-outage-for-several-s… The list of involved services includes https://cbs.centos.org (Koji). Our stable release tracker rpm ( http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm ) requires packages from there and so oVirt from stable release is currently not installable as well on Centos based systems. [centos-ovirt41-candidate] name=CentOS-7 - oVirt 4.1 baseurl=http://cbs.centos.org/repos/virt7-ovirt-41-candidate/$basearch/os/ gpgcheck=0 enabled=1 [centos-ovirt-common-candidate] name=CentOS-7 - oVirt common baseurl= http://cbs.centos.org/repos/virt7-ovirt-common-candidate/$basearch/os/ gpgcheck=0 enabled=1 We are trying to find a recovery solution.

oVirt 4 and 10GbE NICs
by Davide Ferrari 14 Mar '17

14 Mar '17

Hello the oVirt hosts in my cluster have all 10GbE interfaces (bonded 2 by 2), and I was wondering if a single Linux VM with a virtio interface can reach for example 8Gbps. I'm asking because I'm seeing a 100% network usage in some VMs in ovirt VM dashboard but the real traffic in that VM is between 1-2Gbps. Thanks -- Davide Ferrari Senior Systems Engineer

Hello! Thanks - try to remember put cc More information: Our server has separated management Network interfaces (nic) - in HP server i use ILO web managem interface to access server remote console. (HP iLO Integrated Remote Console) I used this renote console to access this freezed node and i was no abel to ping or access ohter host in the same network. Then open this remote console i saw many "vcpu unhandled rdmsr" messages. My node had GbE nic interface with ip address that was not used by ovirtmagmt interface. I was no tabel ping or access this interfiace then node freezed.

After that i was no tabel to Access node over ssh Whole node freezed. Only after reboot i was abel to access thise host again over ssh. You said you saw something on the console. I thought you meant you managed to login. If you didn't, then indeed the problem wasn't (probably) only in networking, but something deeper, in the kernel probably.

iscsi data domain when engine is down
by Devin A. Bougie 14 Mar '17

14 Mar '17

We have an ovirt 4.1 cluster with an iSCSI data domain. If I shut down the entire cluster and just boot the hosts, none of the hosts login to their iSCSI sessions until the engine comes up. Without logging into the sessions, sanlock doesn't obtain any leases and obviously none of the VMs start. I'm sure there's something I'm missing, as it looks like it should be possible to run a hosted engine on a cluster using an iSCSI data domain. Any pointers or suggestions would be greatly appreciated. Many thanks, Devin

Serious Trouble - Lost Domains
by JC Clark 14 Mar '17

14 Mar '17

Dear Fellows and Fellettes, I am having serious disaster problems. After a power transformer outside the building literally exploded, surged and fried the motherboard to the main SPM domain computer in my Ovirt 4.0 system. After getting the computer working again with a new mother board. I managed to basically loose integrity of the old engine. I have rebuilt the engine. I have backups of the old engine and 4 data domains an ISO domain and an export domain which appear to not be damaged. They are all accessible from the CL. I had to create a new host and SPM. How do I get the floating domains into the new Engine? I have 1 storage container (85GB) I must get back. MUST GET BACK!! I really appreciate you reading my sob story. Hope you can help.. Thank You much

We have 4 idempiere-* VMs in an older cluster and we can search for VMs based on all sorts of strings, but if it contains idempiere it shows: 2017-03-13 11:27:33,268 INFO [org.ovirt.engine.core.bll.SearchQuery] (default task-19) [] ResourceManager::searchBusinessObjects - erroneous search text - ''Vms: idempiere'' Can anyone else duplicate this problem in their environment?
