OVA import does not upload disks
by Paolo Airaldi 21 Jul '20

21 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

VDSM HOST ISSUE - Message timeout which can be caused by communication issues
by lu.alfonsi＠almaviva.it 20 Jul '20

20 Jul '20

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

oVirt install questions
by David White 20 Jul '20

20 Jul '20

I'm reading through all of the documentation at https://ovirt.org/documentation/, and am a bit overwhelmed with all of the different options for installing oVirt. My particular use case is that I'm looking for a way to manage VMs on multiple physical servers from 1 interface, and be able to deploy new VMs (or delete VMs) as necessary. Ideally, it would be great if I could move a VM from 1 host to a different host as well, particularly in the event that 1 host becomes degraded (bad HDD, bad processor, etc...) I'm trying to figure out what the difference is between an oVirt Node and the oVirt Engine, and how the engine differs from the Manager. I get the feeling that `Engine` = `Manager`. Same thing. I further think I understand the Engine to be essentially synonymous with a vCenter VM for ESXi hosts. Is this correct? If so, then what's the difference between the `self-hosted` vs the `stand-alone` engines? oVirt Engine requirements look to be a minimum of 4GB RAM and 2CPUs. oVirt Nodes, on the other hand, require only 2GB RAM. Is this a requirement just for the physical host, or is that how much RAM that each oVirt node process requires? In other words, if I have a physical host with 12GB of physical RAM, will I only be able to allocate 10GB of that to guest VMs? How much of that should I dedicated to the oVirt node processes? Can you install the oVirt Engine as a VM onto an existing oVirt Node? And then connect that same node to the Engine, once the Engine is installed? Reading through the documentation, it also sounds like oVirt Engine and oVirt Node require different versions of RHEL or CentOS. I read that the Engine for oVirt 4.4.0 requires RHEL (or CentOS) 8.2, whereas each Node requires 7.x (although I'll plan to just use the oVirt Node ISO). I'm also wondering about storage. I don't really like the idea of using local storage, but a single NFS server would also be a single point of failure, and Gluster would be too expensive to deploy, so at this point, I'm leaning towards using local storage. Any advice or clarity would be greatly appreciated. Thanks, David Sent with ProtonMail Secure Email.

If I configure fence for ovirt hosts, is the fence system used to fence host or to fence the vm running on the host ?

Info on transporting a gluster storage domain
by Gianluca Cecchi 19 Jul '20

19 Jul '20

Hello, I have env1 and env2, both in 4.3 and both configured as single host HCI environments. On both I have the predefined hosted_storage, data and vmstore gluster storage domains. On env1 I have hosted_storage and data on a disk, and vmstore on a whole different disk. I also have a "big2" gluster storage domain created in another disk in a second time. I want to scratch env1 but preserve and then import vmstore and big2 storage domains in env2 This "big2" is configured as a PV on the whole 4Tb disk on env1. - nvme1n1 4Tb gluster_vg_4t2 serial: BTLF72840DVK4P0DGN eui.01000000010000005cd2e45c02de4d51 dm-3 NVME,INTEL SSDPEDKX040T7 size=3.6T features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 1:0:1:0 nvme1n1 259:3 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e45c02de4d51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e45c02de4d51 gluster_vg_4t2 lvm2 a-- <3.64t 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_4t2 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_big2 gluster_vg_4t2 Vwi-aot--- <4.35t my_pool 1.36 my_pool gluster_vg_4t2 twi-aot--- <3.61t 1.64 0.18 [root@ovirt ~]# In similar way the vmstore storage domain has: - nvme2n1 1Tb gluster_vg_nvme1n1 serial: PHLF8125037R1P0GGN eui.01000000010000005cd2e4e359284f51 dm-1 NVME,INTEL SSDPE2KX010T7 size=932G features='1 queue_if_no_path' hwhandler='0' wp=rw `-+- policy='service-time 0' prio=0 status=active `- 2:0:1:0 nvme2n1 259:2 active undef running [root@ovirt ~]# pvs /dev/mapper/eui.01000000010000005cd2e4e359284f51 PV VG Fmt Attr PSize PFree /dev/mapper/eui.01000000010000005cd2e4e359284f51 gluster_vg_nvme1n1 lvm2 a-- 931.51g 0 [root@ovirt ~]# [root@ovirt ~]# lvs gluster_vg_nvme1n1 LV VG Attr LSize Pool Origin Data% Meta% Move Log Cpy%Sync Convert gluster_lv_vmstore gluster_vg_nvme1n1 Vwi-aot--- 930.00g gluster_thinpool_gluster_vg_nvme1n1 63.99 gluster_thinpool_gluster_vg_nvme1n1 gluster_vg_nvme1n1 twi-aot--- 921.51g 64.58 1.80 [root@ovirt ~]# I presume the correct way is: - env1 delete and detach vmstore and big2 (without formatting/zeroing) - env2 attach the two disks to the system and then? What should I do at gluster commands level to "import" the already setup gluster bricks/volumes and then at oVirt side to import the corresponding storage domain? BTW: can I import the previous storage domain named "vmstore" giving anothe r name such as vmstore2, not to create conflict with already existing "vmstore" storage domain or the name is hard coded when importing and creating possible conflict? Thanks, Gianluca
