Reinstall failed on 4.4.1.1 with custom kernel settings
by mmarino＠extraordy.com 22 Jul '20

22 Jul '20

Hi, after the upgrade from 4.4.1 to 4.4.1.1, it seems that I cannot reinstall adding custom kernel settings. In my case, I'm trying to add "ixgbe.allow_unsupported_sfp=1" to cmdline but reinstall process fails without showing any relevant error in /var/log/vdsm/vdsm.log. I did the same test on version 4.4.1 and it works without problems. On version 4.4.1 I tried to (1) add a parameter with reinstall, (2) add a second parameter and reinstall, (3) remove all params and reinstall and (4) finally add only one custom param with reinstall. All tests are ok on version 4.4.1 and the problem happens only on version 4.4.1.1. Please, have you some idea on how to solve the issue? Is this a bug? Thank you, Marco

OVA import does not upload disks
by Paolo Airaldi 22 Jul '20

22 Jul '20

Hello, I'm running 4.3.5.4-1.el7. I've exported a VM as OVA and now I'm trying to import it in another Data Center (it's like a DR Data Center) Import runs successfully both from GUI and from Ansible, but imported VM disks are empty and the VM fails to boot. How can I import disks content too? Thanks in advance for any help. Paolo

Hello Gianluca, thanks for opening the bug. I have also reported my test scenario below. (One thing more in my case, the standalone Manager needs to be installed on EL8 and not like documents says on EL7. With EL7 load is gives an error that Engine for EL7 is not avaiable. Document needs to be updated.) --- The same error occurs when trying to add a node to a standalone Engine Manager. Steps to Reproduce: 1. install a standalone Engine Manager on EL8 step by step with this documentation https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manage… 2. install a node using ovirt-node-ng-installer-4.4.1-2020071311.el8.iso 3. try to add the node inside the Engine Manager Log output: 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/vdsmid.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/pki.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - included: /usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/restart_services.yml for ovirtnode1.example.net 2020-07-21 10:14:17 CEST - TASK [ovirt-host-deploy-vdsm : Install ovirt-host package] ********************* 2020-07-21 10:14:17 CEST - 2020-07-21 10:14:17 CEST - fatal: [ovirtnode1.example.net] FAILED! => {"changed": false, "module_stderr": "/bin/sh: /usr/bin/python2: No such file or directory\n", "module_stdout": "", "msg": "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc": 127} 2020-07-21 10:14:17 CEST - { "status" : "OK", "msg" : "", "data" : { "uuid" : "bfb59a41-6672-4115-ba93-1755556b3d11", "counter" : 61, "stdout" : "fatal: [ovirtnode1.example.net] FAILED! => {\"changed\": false, \"module_stderr\": \"/bin/sh: /usr/bin/python2: No such file or directory\\n\", \"module_stdout\": \"\", \"msg\": \"The module failed to execute correctly, you probably need to set the interpreter.\\nSee stdout/stderr for the exact error\", \"rc\": 127}", "start_line" : 54, "end_line" : 55, "runner_ident" : "230c108e-cb2a-11ea-97da-00155d120809", "event" : "runner_on_failed", "pid" : 28965, "created" : "2020-07-21T08:14:16.528490", "parent_uuid" : "00155d12-0809-c845-9450-0000000001a1", "event_data" : { "playbook" : "ovirt-host-deploy.yml", "playbook_uuid" : "3a66c11c-02f9-492a-937d-21f1386e492d", "play" : "all", "play_uuid" : "00155d12-0809-c845-9450-000000000006", "play_pattern" : "all", "task" : "Install ovirt-host package", "task_uuid" : "00155d12-0809-c845-9450-0000000001a1", "task_action" : "yum", "task_args" : "", "task_path" : "/usr/share/ovirt-engine/ansible-runner-service-project/project/roles/ovirt-host-deploy-vdsm/tasks/packages.yml:2", "role" : "ovirt-host-deploy-vdsm", "host" : "ovirtnode1.example.net", "remote_addr" : "ovirtnode1.example.net", "res" : { "module_stdout" : "", "module_stderr" : "/bin/sh: /usr/bin/python2: No such file or directory\n", "msg" : "The module failed to execute correctly, you probably need to set the interpreter.\nSee stdout/stderr for the exact error", "rc" : 127, "_ansible_no_log" : false, "changed" : false }, "start" : "2020-07-21T08:14:15.365609", "end" : "2020-07-21T08:14:16.528185", "duration" : 1.162576, "ignore_errors" : null, "event_loop" : null,a "uuid" : "bfb59a41-6672-4115-ba93-1755556b3d11" } }

ovirt 4.4 installation issues
by Markus Schaufler 21 Jul '20

21 Jul '20

Hi all, in our environment, CentOS7 and RHEL7 for the most part (Ovirt 4.3 and RHV 4.3), we are able to set a proxy directly in /etc/yum.conf (or on the single repo) to momentarily bypass some network restrictions. The proxy settings looks like this: proxy=http://our-proxy.domain:8080 proxy_username=user proxy_password=password But is also works properly when it is set directly from CLI, and this is the one we use more often: export http_proxy=http://user:password@our-proxy.domain:8080 export https_proxy=https://user:password@our-proxy.domain:8080 We are having difficulties to set the same proxy on CentOS8 / Ovirt 4.4.x. There is no way the proxy settings allows us to run "yum update". Extra Packages for Enterprise Linux 8 - x86_64 0.0 B/s | 0 B 00:00 Errors during downloading metadata for repository 'ovirt-4.4-epel': - Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Error: Failed to download metadata for repo 'ovirt-4.4-epel': Cannot prepare internal mirrorlist: Curl error (56): Failure when receiving data from the peer for https://mirrors.fedoraproject.org/metalink?repo=epel-8&arch=x86_64&infra=st… [Received HTTP code 407 from proxy after CONNECT] Can somebody maybe point us to a solution? The above command is extracted by 'yum update' after a clean installation of Ovirt 4.4.1-2020070811 (but the same issue happened on previous versions and Nightly versions too). Thank you, Markus

Slow ova export performance
by francesco＠shellrent.com 20 Jul '20

20 Jul '20

Hi All, I'm facing a really slow export ov vms hosted on a single node cluster, in a local storage. The Vm disk is 600 GB and the effective usage is around 300 GB. I estimated that the following process would take up about 15 hours to end: vdsm 25338 25332 99 04:14 pts/0 07:40:09 qemu-img measure -O qcow2 /rhev/data-center/mnt/_data/6775c41c-7d67-451b-8beb-4fd086eade2e/images/a084fa36-0f93-45c2-a323-ea9ca2d16677/55b3eac5-05b2-4bae-be50-37cde7050697 A strace -p of the pid shows a slow progression to reach the effective size. lseek(11, 3056795648, SEEK_DATA) = 3056795648 lseek(11, 3056795648, SEEK_HOLE) = 13407092736 lseek(14, 128637468672, SEEK_DATA) = 128637468672 lseek(14, 128637468672, SEEK_HOLE) = 317708828672 lseek(14, 128646250496, SEEK_DATA) = 128646250496 lseek(14, 128646250496, SEEK_HOLE) = 317708828672 lseek(14, 128637730816, SEEK_DATA) = 128637730816 lseek(14, 128637730816, SEEK_HOLE) = 317708828672 lseek(14, 128646774784, SEEK_DATA) = 128646774784 lseek(14, 128646774784, SEEK_HOLE) = 317708828672 lseek(14, 128646709248, SEEK_DATA) = 128646709248 The process take a single full core, but i don't think this is the problem. The I/O is almost nothing. Any idea/suggestion? Thank you for your time Regards

Good morning, i have installed a new ovirt 4.3.10 enviroment but sometimes on the events of some hosts i read this error message: VDSM node-1-ra command Get Host Capabilities failed: Message timeout which can be caused by communication issues Due to this issue hosts are in unresponsive state and the only way to resolve this is and activate host in the cluster, is to restart the ovirt engine service. Can anyone help me? Thanks in advance Luigi
