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

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!

Issues importing VM from Export Domain
by Wesley Stewart 14 Aug '17

14 Aug '17

I was doing some testing and recently rebuilt my homelab using a Xeon-D based board. I did not have anything too important, so I thought this would be a good chance to test re-importing my backups and seeing how well it works. I created a new export domain and copied all of my old VM's into this new export domain. But the problem is, the images are in a "Locked" state. The console tells me: Aug 13, 2017 11:59:38 PM Failed to import Vm Clonezilla_Server_BACKUP_20170807_010018 to Data Center OVIRT-Datacenter, Cluster OVIRT-Cluster Aug 13, 2017 11:59:38 PM VDSM command DeleteImageGroupVDS failed: Image does not exist in domain: u'image=a5c8780e-3166-4801-b71a-1ef7d9b21783, domain=35cd8fab-4347-4201-bf4e-4dcbde19fb0f' Aug 13, 2017 11:59:37 PM VDSM OVIRT-Host command HSMGetAllTasksStatusesVDS failed: low level Image copy failed This happens for all the VMs shown in the Export-Domain. I also tried the unlock_entity.sh script, but I am having some postgres access issues: unlock_entity.sh -r -t vm -i Clonezilla_Server -s localhost psql: FATAL: no PostgreSQL user name specified in startup packet FATAL: Cannot execute sql command: --file=./unlock_entity.sql I thought I could just poke around the database by running: psql -d engine -U postgres But this also fails psql: FATAL: Peer authentication failed for user "postgres" Was just hoping someone had some suggestions. I can't event delete this VM! Thanks!

oVIRT Node / Network Manager / oVirt 4.1
by Devin Acosta 13 Aug '17

13 Aug '17

I noticed that for some reason when I am running oVirt node on my hosts and disabled NetworkManager it appears that it kept turning itself back on, and my understanding is that Network Manager should be disabled. I had to force remove Network Manager in order to get it to stay disabled. I have been seeing strangeness with my VM's where they disconnect, and where hosted-engine keeps trying to non-stop migrate to another host. Just wanted to first confirm about Network Manager and oVirt Node image. -- Devin Acosta Red Hat Certified Architect

Scheduling policy time interval and others
by wodel youchi 13 Aug '17

13 Aug '17

Hi, When reading about scheduling policy, I am faced with some variables, but I cannot find any explanation on how they are defined or where are they defined. For example : - HighUtilization: Expressed as a percentage. If the host runs with CPU usage at or above the high utilization value for the* defined time interval* . - CpuOverCommitDurationMinutes: Sets the time (in minutes) that a host can run a CPU load outside of the* defined utilization values* before the scheduling policy takes action. Time interval and utilization values, where are these values?

Need some help understanding memory allocation
by Wesley Stewart 11 Aug '17

11 Aug '17

I am a little confused on why my CentOS box is using so much RAM. I currently have a small test setup which only has *12GB* of ram total. When I log into the administrative interface it tells me: *Memory* 4.3 Available of 15.5 GiB Over commit: 39% (allocated 45%) 11.1 GB Used Currently I am only running 3 VMs with memory allocations as follows: Defined Memory: 1024 MB Physical Memory Guaranteed: 1024 MB Defined Memory: 3072 MB Physical Memory Guaranteed: 3072 MB Defined Memory: 2048 MB Physical Memory Guaranteed: 2048 MB *Or 6144MB used by VM* If I SSH into my ovirt host, and run TOP and sort by memory, the top usage items are: 31896 qemu *21.5%* 727:21.44 qemu-kvm 6008 qemu *14.6%* 190:33.70 qemu-kvm 3019 ovirt *13.6%* 35:47.64 java 5800 qemu *8.5%* 784:26.88 qemu-kvm 2565 ovirt *3.9%* 62:58.00 java Everything else is pretty small compared, but for the OVIRT/QEMU we roughly get *Total: 62% = 7.45GB* So I am a bit confused as to the Ram being reported to me by the system (15.5GGB, but the system only has 12GB), and assuming OVIRT is using around 7-8GB, does a bare minimal install of CentOS really need 4-5GB of Ram to run? This is a bare minimal install of CentOS7 running only Webmin and oVirt. I think there are several things I don't understand here, and I am quite new to oVirt and would like to learn, so please excuse my inexperience if this is a silly question! Thanks either way, I am really happy I ditched my ESXi box :D

Hi guys, good morning/night . first of all thanks to all the community and the whole team, you are doing a great effort . Today Im having an issue with ovirt 4.1.2 running as hosted engine over nfs. and data storage over iscsi. I found out of the problem when I tried to migrate one vm to another host and I got an error, so I powered off the vm's on that host and started them on the backup host with no problem, then I set the first host into mainteinance mode and after some minutes I restarted it(as usual). when it came back online, the whole dc turned RED as unavailable. can anyone please help me out? thanks, JP

q35 + virtio-scsi: contention for sda between cdrom and disk
by Richard Chan 10 Aug '17

10 Aug '17

q35 + virtio-scsi VM won't start because both cdrom and harddisk are mapped to sda I have created a q35 VM using virt-shell: add vm --template-id 00000000-0000-0000-0000-000000000000 --cluster-id 16dc2c02-7d14-40a9-b170-cfdfdf63565b --name TESTVM --virtio_scsi-enabled 1 --os-type rhel_7x64 --custom_emulated_machine pc-q35-rhel7.3.0 When I try to start the VM vdsm shows: <disk device="cdrom" snapshot="no" type="file"> <address bus="0" controller="0" target="0" type="drive" unit="0" /> <source file="" startupPolicy="optional" /> <target bus="sata" dev="sda" /> <readonly /> </disk> <disk device="disk" snapshot="no" type="file"> <address bus="0" controller="0" target="0" type="drive" unit="0" /> <source file="/rhev/data-center/5ac1ff95-d7ac-4b42-89d5-241eef81b9a6/f9aaa65a-0ac7-4c61-a27d-15af39016419/images/ea86a e1b-893a-47ac-bde8-8c54b4c30e80/ee90830a-7ce8-452b-ba14-2f79f5c7250a" /> <target bus="scsi" dev="sda" /> <serial>ea86ae1b-893a-47ac-bde8-8c54b4c30e80</serial> <driver cache="none" error_policy="stop" io="threads" name="qemu" type="qcow2" /> </disk> As a result the VM won't start. If the disk is virtio (vda) it works. Anyway to remove the cdrom device from the VM definition? -- Richard Chan
