Re: ovirt api vm snapshot cloning error

Hi Peter, Would you mind reporting a bug on this issue you saw? To me, it looks like sync/timing issue between snapshot state('OK) and disk state('Locked'). Can you also please check if the disk that is reported as locked is indeed locked at the time the error is reported? Please add this info to the bug and all relevant scripts. As a workaround, please consider adding an additional wait for all the VM disks to also reach 'OK' state.

Can't start the VM ... There are no hosts to use. Check that the cluster contains at least one host in Up state.
by daniel＠djj-consultants.com 22 Aug '18

22 Aug '18

Hello I'm stuck since 3 days trying to find out why I can't start a VM. I tried to start with the GUI (ovirt-manager) and ovirt-shell action vm 5a61762e-ff97-47b6-891b-2a05d38ebc45 start ================================================================================== status: 400 reason: Bad Request detail: There are no hosts to use. Check that the cluster contains at least one host in Up state. ================================================================================= list hosts; id : f76a3135-8a3b-4c5b-b7bd-4c539e93d944 name : ovirt01.xxx.yy id : 1f545c5a-06a7-497c-914a-29e81b1b80d7 name : ovirt02.xxx.yy Theses 2 hosts are running other VMs without any problem. I tried to export the VM and re-import it but the problem still present. I'm thinking of something like a lease for HA that went bad somewhere and that's maybe why the VM don't want to start but I can't find out. I went to postgresql (engine DB) to find out some clues but nothing yet. Is there someone that can send me some clues or better a solution for this issue Hosted engine is Version 4.2.4.5-1.el7 Hosts are running :ovirt-host-4.2.3-1.el7.x86_64 Storage use ISCSI with a Storinator from 45Drives (Freenas 11) Thanks

Hosted Engine on single server
by Peter Hudec 22 Aug '18

22 Aug '18

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Hi guys, I need to deal with following scenario. I have 2 servers with local storage, no shared storage. The question is how to install the oVirt with Hosted Engine. 1) is there a way how to install the HE on local storage. There will be no redundancy, but it's DEV system. 2) Am I able to use host with local storage and remote at once? If the server uses local store the oVirt will create a separate DC for the hosts. Am I able to attach also remote storage there? 3) could be HE still installed on bare metal? I guess yes. regards Peter - -- *Peter Hudec* Infraštruktúrny architekt phudec(a)cnc.sk <mailto:phudec@cnc.sk> *CNC, a.s.* Borská 6, 841 04 Bratislava Recepcia: +421 2 35 000 100 Mobil:+421 905 997 203 *www.cnc.sk* <http:///www.cnc.sk> -----BEGIN PGP SIGNATURE----- iQIzBAEBCgAdFiEEqSUbhuEwhryifNeVQnvVWOJ35BAFAlt8laYACgkQQnvVWOJ3 5BASPA/9GDTT9YKHQHM2nDH0HGyunFmYZOTAuwnkzvTCrRF4O/oBiGmu1ovYMDpi R9uq+5vhPHDMJc9WGS37xL13hM1FCCmFDtETI2Q3pAliWq4R4n/tKriObMgOFCmA Vdqg5Yz+vrkLhdtZKDxMOPnJyBD+ET2ewaISEKgmS9cUQYnBU4ADqfDmHfnpPH8P 4EoAeZEYpO/7GICuW6SzLpbv19bhXnpnRBcRrYRqzU7cYEhyPCv0c/M4In/gOoAn ZX9h0LQoZhxK0xkFvUAqaUoO4BRwA/PjxDzz58upGtstO2JZehvpxWeVMD3aNbhb IBn6EnmZtSV9tNyifxegTluTcZAYhrIw8vpgpNHVFzRV7Q8/o0nfGIuWeNrCRDsG spzm9BNahk7IlEhquJu8XoGT8GgPAoeIFEzSfj55MH792lmfn05n3HaVtVv94WK/ FdBcVu4CxYMWPHWRycQc7OYc2S/aHhIzWl3C+/d4Y6yzb0u374ffLdkqO6c6u3Dm khIf0b+xhy0g0EhzvcaQ6T/yPjsB+wTcQbCnlCARbhYMuB4zvzfIAj3fzFOTgSm2 0rhG6KZ1G2hKrzBJGW2reOh9hUzba9QrwxVcHqewxPrf8/uddldZyzgLu5S/B7gl LVBY3wJHyph6hrRYsJdfOaEIQdoUUhJ3nh0VhjAplHLa2JJbC9A= =pEM/ -----END PGP SIGNATURE-----

live migration of hosted engine between two hosts
by Douglas Duckworth 22 Aug '18

22 Aug '18

Hi I am trying to live migrate my hosted engine between two hosts. Both hosts are now up. The hosted engine exists on shared NFS storage mounted on both hypervisors. Though when I tried to migrate the VM I am told that's not possible. Could this be since I never defined migration network? If so I tried doing that in the oVirt UI as described https://ovirt.org/documentation/admin-guide/chap-Logical_Networks/ though many of these options have changed.

vdsm hook
by 董青龙 21 Aug '18

21 Aug '18

Hi all, I want to write a hook in which name or id of the vm can be acquired and the hook should be executed before the vm shutdown. I could acquire name or id of the vm in a before_vm_start hook using "hooking.read_domxml()". However, it did not work in a before_vm_destroy hook. So what should I do? Can Anyone give me some advice? Thanks a lot!

how to reset engine-config parameter?
by Gianluca Cecchi 21 Aug '18

21 Aug '18

Hello, I tried to setup UserDefinedVMProperties to disable macspoofing for a vm that has to work as hypervisor. Then I remembered suggestion of Simone about creating vnic profile as an alternate method and set there the filter. I think I have done something wrong because if I create now a new vm and try to power on it I get VM test is down with error. Exit message: Hook Error: ('',). Perhaps I failed the syntax to reset the value of UserDefinedVMProperties ?

Hosted Engine setup issues
by Jeremy Tourville 21 Aug '18

21 Aug '18

If I try to setup hosted engine with the option to use Ansible it eventually fails on me. See https://lists.ovirt.org/archives/list/users@ovirt.org/thread/LPK7OGFALSQFAN… However if I run hosted-engine --deploy --noansible the setup does complete. There is further trouble though, it seems the networks are not being configured properly. If I browse to Compute>Hosts>Hostname and click on the Setup Host Networks button I am presented with a new window that contains an unassigned logical network of "oivrtmgmt" On the left side pane there are two columns for Interfaces and Assigned Logical Networks. Both of those columns are completely empty. I think if I understand correctly the interfaces column should at least have some info in it. [cid:bb1f29b4-888c-410a-9b47-7589f866539a] So my best guess is that for some unknown reason (at least to me) the Engine doesn't '"know how to get setup properly" either with or without Ansible. That's about as well as I can describe it. I hope it makes sense.... Anyone have ideas on what is going wrong here? Thanksfor any troubleshooting advice you can provide!

Hello, I get the following messages. "Cluster Default uses IPTables firewall, which has been deprecated in 4.2 of the engine, and will no longer be supported starting with version 4.3. Make sure to switch to Firewalld before upgrading to 4.3." If the correct way to change to firewalld edit cluster, and run reinstall? Thanks, Paul S.

after upgrade from 4.2.3 to 4.2.5, problems with consoles + cockpit
by Jason Keltz 20 Aug '18

20 Aug '18

Hi.. After an upgrade from 4.2.3 to 4.2.5 last week, I notice that I have a console + cockpit problem. Immediately following the upgrade, everything seemed to be working fine. However, today, a couple of days after the upgrade, when I try to view any CentOS VM console, virt-viewer starts, and I see "Connected to graphic server", but there's no console output. This happens on all Linux VMs, though on my two windows VMs, the console still works. If I restart a Linux VM, I get the console back again, but what made me lose access to all the consoles? In addition, if I right click on one of my 4 hosts, and choose "Host Console", it connects to cockpit which reports: "No VM is running or defined on this host" even though there are plenty. I brought one host into maintenance mode, and rebooted it. I then started a few VMs there, and cockpit still doesn't show anything running. All of the hosts have all available ovirt updates, and are running the latest CentOS 7 kernel + O/S updates. Any ideas? There is no issue with firewall. Jason.

info about changing engine ip mode from dhcp to static
by Gianluca Cecchi 17 Aug '18

17 Aug '18

Hello, a colleague of mine installed oVirt engine 4.2.5 on a test CentOS 7.5 system and in its initial configuration he configured its ip via dhcp (using static ip assignment configured at dhcp server side). Now he would like to maintain the same ip/hostname for the engine but with a static configuration on the server. Any hint about how to achieve this? Thanks in advance, Gianluca

Poor performance of oVirt Export Domain
by Aleksey.I.Maksimov＠yandex.ru 17 Aug '18

17 Aug '18

Hello I deployed a dedicated server (fs05.holding.com) on CentOS 7.5 and created a VDO volume on it. The local write test in the VDO volume on this server gives us an acceptable result # dd if=/dev/zero of=/mnt/vdo-vd1/nfs/testfile count=1000000 1000000+0 records in 1000000+0 records out 512000000 bytes (512 MB) copied, 6.26545 s, 81.7 MB/s The disk capacity of the VDO volume is connected to the oVirt 4.2.5 cluster as the Export Domain via NFS. I'm seeing a problem with the low performance of Export Domain. Snapshots of virtual machines are copied very slowly to the Export Domain, approximately 6-8 MB/s. At the same time, if I try to run a write test in an mounted NFS-directory on any of the oVit cluster hosts, I get about 50-70 MB/s. # dd if=/dev/zero of=/rhev/data-center/mnt/fs05.holding.com:_mnt_vdo-vd1_nfs_ovirt-vm-backup/testfile count=10000000 10000000+0 records in 10000000+0 records out 5120000000 bytes (5.1 GB) copied, 69.5506 s, 73.6 MB/s Help me understand the reason for the slow copying to Export Domain on oVirt.

oVirt 4.2.5 : VM snapshot creation does not work : command HSMGetAllTasksStatusesVDS failed: Could not acquire resource
by Aleksey Maksimov 17 Aug '18

Hello We use oVirt 4.2.5.2-1.el7 (Hosted engine / 4 hosts in cluster / about twenty virtual machines) Virtual machine disks are located on the Data Domain from FC SAN. Snapshots of all virtual machines are created normally. But for one virtual machine, we can not create a snapshot. When we try to create a snapshot in the oVirt web console, we see such errors: Aug 13, 2018, 1:05:06 PM Failed to complete snapshot 'KOM-APP14_BACKUP01' creation for VM 'KOM-APP14'. Aug 13, 2018, 1:05:01 PM VDSM KOM-VM14 command HSMGetAllTasksStatusesVDS failed: Could not acquire resource. Probably resource factory threw an exception.: () Aug 13, 2018, 1:05:00 PM Snapshot 'KOM-APP14_BACKUP01' creation for VM 'KOM-APP14' was initiated by petya@sub.holding.com@sub.holding.com-authz. At this time on the server with the role of "SPM" in the vdsm.log we see this: ... 2018-08-13 05:05:06,471-0500 INFO (jsonrpc/0) [jsonrpc.JsonRpcServer] RPC call VM.getStats succeeded in 0.00 seconds (__init__:573) 2018-08-13 05:05:06,478-0500 INFO (jsonrpc/5) [jsonrpc.JsonRpcServer] RPC call Image.deleteVolumes succeeded in 0.05 seconds (__init__:573) 2018-08-13 05:05:06,478-0500 INFO (tasks/3) [storage.ThreadPool.WorkerThread] START task bb45ae7e-77e9-4fec-9ee2-8e1f0ad3d589 (cmd=<bound method Task.commit of <vdsm.storage.task.Task instance at 0x7f06b85a2128>>, args=None) (threadPool:208) 2018-08-13 05:05:07,009-0500 WARN (tasks/3) [storage.ResourceManager] Resource factory failed to create resource '01_img_6db73566-0f7f-4438-a9ef-6815075f45ea.cdf1751b-64d3-42bc-b9ef-b0174c7ea068'.
