USB3 redirection
by Rik Theys 19 Apr '22

19 Apr '22

Hi, I'm trying to assign a USB3 controller to a CentOS 7.4 VM in oVirt 4.1 with USB redirection enabled. I've created the following file in /etc/ovirt-engine/osinfo.conf.d: 01-usb.properties with content os.other.devices.usb.controller.value = nec-xhci and have restarted ovirt-engine. If I disable USB-support in the web interface for the VM, the xhci controller is added to the VM (I can see it in the qemu-kvm commandline), but usb redirection is not available. If I enable USB-support in the UI, no xhci controller is added (only 4 uhci controllers). Is there a way to make the controllers for usb redirection xhci controllers?

OVN routing and firewalling in oVirt
by Gianluca Cecchi 19 Apr '22

19 Apr '22

Hello, how do we manage routing between different OVN networks in oVirt? And between OVN networks and physical ones? Based on architecture read here: http://openvswitch.org/support/dist-docs/ovn-architecture.7.html I see terms for logical routers and gateway routers respectively but how to apply to oVirt configuration? Do I have to choose between setting up a specialized VM or a physical one: is it applicable/advisable to put on oVirt host itself the gateway functionality? Is there any security policy (like security groups in Openstack) to implement? Thanks, Gianluca

Install hosted-engine - Task Get local VM IP failed
by florentl 10 Mar '22

Hi all, I try to install hosted-engine on node : ovirt-node-ng-4.2.3-0.20180518. Every times I get stuck on : [ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed": true, "cmd": "virsh -r net-dhcp-leases default | grep -i 00:16:3e:6c:5a:91 | awk '{ print $5 }' | cut -f1 -d'/'", "delta": "0:00:00.108872", "end": "2018-06-01 11:17:34.421769", "rc": 0, "start": "2018-06-01 11:17:34.312897", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []} I tried with static IP Address and with DHCP but both failed. To be more specific, I installed three nodes, deployed glusterfs with the wizard. I'm in a nested virtualization environment for this lab (Vmware Esxi Hypervisor). My node IP is : 192.168.176.40 / and I want the hosted-engine vm has 192.168.176.43. Thanks, Florent

VM hanging at sustained high throughput
by David Johnson 08 Mar '22

08 Mar '22

Hi ovirt gurus, This is an interesting issue, one I never expected to have. When I push high volumes of writes to my NAS, I will cause VM's to go into a paused state. I'm looking at this from a number of angles, including upgrades on the NAS appliance. I can reproduce this problem at will running a centos 7.9 VM on Ovirt 4.5. *Questions:* 1. Is my analysis of the failure (below) reasonable/correct? 2. What am I looking for to validate this? 3. Is there a configuration that I can set to make it a little more robust while I acquire the hardware to improve the NAS? *Reproduction:* Standard test of file write speed: [root@cen-79-pgsql-01 ~]# dd if=/dev/zero of=./test bs=512k count=4096 oflag=direct 4096+0 records in 4096+0 records out 2147483648 bytes (2.1 GB) copied, 1.68431 s, 1.3 GB/s Give it more data [root@cen-79-pgsql-01 ~]# dd if=/dev/zero of=./test bs=512k count=12228 oflag=direct 12228+0 records in 12228+0 records out 6410993664 bytes (6.4 GB) copied, 7.22078 s, 888 MB/s The odds are about 50/50 that 6 GB will kill the VM, but 100% when I hit 8 GB. *Analysis:* What I think appears to be happening is that the intent cache on the NAS is on an SSD, and my VM's are pushing data about three times as fast as the SSD can handle. When the SSD gets queued up beyond a certain point, the NAS (which places reliability over speed) says "Whoah Nellie!", and the VM chokes. *David Johnson*

Host needs to be reinstalled after configuring power management
by Andrew DeMaria 03 Feb '22

03 Feb '22

Hi, I am running ovirt 4.3 and have found the following action item immediately after configuring power management for a host: Host needs to be reinstalled as important configuration changes were applied on it. The thing is - I've just freshly installed this host and it seems strange that I need to reinstall it. Is there a better way to install a host and configure power management without having to reinstall it after? Thanks, Andrew

Import an exported VM using Ansible
by paolo＠airaldi.it 26 Jan '22

26 Jan '22

Hello everybody! I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook. I'm able to: - Create a snapshot of the source VM - create a clone from the snapshot - remove the snapshot - attach an Export Domain - export the clone to the Export Domain - remove the clone - detach the Export domain from the source Datacenter and attach to the destination. Unfortunately I cannot find a module to: - import the VM from the Export Domain - delete the VM image from the Export Domain. Any hint on how to do that? Thanks in advance. Cheers. Paolo PS: if someone is interested I can share the playbook.

I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log {2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information. Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431 or is it because the vm fails or dies or ???
