New install
by info＠worldhostess.com 21 Sep '20

21 Sep '20

I have an issue with new installation. The server name is changing all the time and it keep disconnecting me. Plus it is impossible to log in as admin. The install went through without any issues, but it seems something is wrong. Server: engine01.xxxx.com Log in with your server user account. Server: node01.xxxx.com Log in with your server user account.

routing policy problem in ovirt 4.4
by g.vasilopoulos＠uoc.gr 19 Sep '20

19 Sep '20

Hello I created a cluster of ovirt 4.4 with 5 servers, I have a diferent gateway, ovirtmgmt and display network. In 4.4 routing is managed from network manager. Network manager seems to "forget" and recreate the route each time. So I cannot connect to the virtual machines console unless I run a ping for about a minute on the display network ip of the hypervisor, so network manager "wakes up" and "recreates" the route. I use this work around but it is not something that a user can do. What is the proper way to do this ? Thank you

New oVirt Install - Host Engine Deployment Fails
by mblanton＠vnet.net 18 Sep '20

18 Sep '20

I am attempting a new oVirt install. I have two nodes installed (with oVirt Node 4.4). I have NFS shared storage for the hosted engine. Both nodes are Dell quad core Xeon CPUs with 32GB of RAM. Both have been hypervisors before, XCP-NG and Proxmox. However I'm very interested to learn oVirt now. The hosted engine deployment (through cockpit) fails during the "Finish" stage. I do see the initial files created on the NFS storage. [ INFO ] TASK [ovirt.hosted_engine_setup : Convert CPU model name] [ ERROR ] fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute ''\n\nThe error appears to be in '/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/create_target_vm/01_create_target_hosted_engine_vm.yml': line 105, column 16, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n# - debug: var=server_cpu_dict\n ^ here\n\nThere appears to be both 'k=v' shorthand syntax and YAML in this task.

I can event SSH into the HostedEngineLocal instance. [root@ovirt-node01]# virsh --readonly list Id Name State ----------------------------------- 1 HostedEngineLocal running Looking at the "Convert CPU model name" task: https://github.com/oVirt/ovirt-ansible-hosted-engine-setup/blob/master/task… set_fact: cluster_cpu_model: "{{ server_cpu_dict[cluster_cpu.type] }}" server_cpu_dict is good, I can find that in the logs, cluster_cpu is undefined. But this is normal correct? The Cluster CPU type is "undefined" until the first host is added to the cluster. The error makes it seems that server_cpu_dict and not cluster_cpu.type is the problem. I'm not sure this is really the problem, but that is the only undefined variable I can find. Any advice or recommendation is appreciated -Thanks in advance

Re: Random hosts disconnects
by Artur Socha 18 Sep '20

Hi Anton, I am not sure if changing this value would fix the issue. Defaults are pretty high. For example vdsHeartbeatInSeconds=30seconds, vdsTimeout=180seconds, vdsConnectionTimeout=20seconds. Do you still have relevant logs from the affected hosts: * /var/logs/vdsm/vdsm.log* * /var/logs/vdsm/supervdsm.log* Please look for any jsonrpc errors ie. write/read errors or (connection) timeouts. Storage related warnings/errors might also be relevant. Plus system logs if possible: *journalctl -f /usr/share/vdsm/vdsmd* *journalctl -f /usr/sbin/libvirtd* In order to get system logs from particular time period please combine it with the following example using -S -U options: *journalctl -S "2020-01-12 07:00:00" -U "2020-01-12 07:15:00" * I haven't a clue what to look there for besides any warnings/errors or anything else that seems .... unusual.

Hi all, I'm having some issues with one VM. The VM won't start and it's showing problems with the virtual disks so I started the VM without any disks and trying to hot adding the disk and that's fail too. The servers are connected thru FC, all the other VMs are working fine. Any ideas?. Thanks!!

Low Performance (KVM Vs VMware Hypervisor) When running multi-process application
by Rav Ya 17 Sep '20

17 Sep '20

Hello Everyone, Please advice. Any help will be highly appreciated. Thank you in advance. Test Setup: 1. oVirt Centos 7.8 Virtulization Host 2. Guest VM Centos 7.8 (Mutiqueue enabled 6 vCPUs with 6 Rx Tx Queues) 3. The vCPUs are configured for host pass through (Pinned CPU). The Guest VM runs the application in userspace. The Application consists of the parent process that reads packets in raw socket mode from the interface and forwards then to child processes (~vCPUs) via IPC (shared memory – pipes). *The performance (throughput / CPU utilization) that I get with KVM is half of what I get with VMware.* Any thoughts on the below observations? Any suggestions? - KVM Guest VMs degraded performance when running multi-process applications. - High FUTEX time (Seen on the Guest VM when passing traffic). - *High SY: *System CPU time spent in kernel space (Seen on both Hypervisor and the Guest VMs only when running my application.) -Rav Ya
