Group Consumer on Quota not trickling down to Users in Group?
by Brian T 28 May '19

28 May '19

Good morning all, I have a problem with how Groups are handled with Quotas. Currently, when you assign a Group to a Quota, it does not make all the Users in that Group a Consumer in that Quota. As the documentation states, one would have to add each individual User in that Quota. Is this the intended design? I figure, much like how Groups are handled with other oVirt functions, that the Users in a Group assigned to a Quota should also inherit being a Consumer in that Quota. Thank you.

Can't run nested virtualization
by nicolas＠devels.es 28 May '19

28 May '19

Hi, We're running oVirt version 4.3.3, and trying to configure one of the hosts to support Nested Virtualization, but when installing the nested host it claims it doesn't support hardware virtualization. On the physical host, we've enabled nested virtualization: # cat /sys/module/kvm_intel/parameters/nested Y Content of /etc/modprobe.d/kvm.conf: options kvm_intel nested=1 options kvm_intel enable_shadow_vmcs=1 options kvm_intel enable_apicv=1 options kvm_intel ept=1 I created a VM to run on that host, which will be the nested host. I try to deploy it but the engine will show it failed because: 2019-05-10 09:11:32,006+01 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (VdsDeploy) [6381e662] EVENT_ID: VDS_INSTALL_IN_PROGRESS_ERROR(511), An error has occurred during installation of Host host1: Failed to execute stage 'Setup validation': Hardware does not support virtualization. Am I missing something here? Thanks.

oVirt 4.3.4 RC1 to RC2 - Dashboard error / VM/Host/Gluster Volumes OK
by Strahil Nikolov 28 May '19

28 May '19

Hello All, Just upgraded my engine from 4.3.4 RC1 to RC2 and my Dashboard is giving an error (see attached screenshot) despite everything seem to end well: Error! Could not fetch dashboard data. Please ensure that data warehouse is properly installed and configured. I have checked and the VMs and Hosts + Gluster Volumes arep roperly detected (yet all my VMs are powered off since before RC2 upgrade). Any clues that might help you solve that before I roll back (I have a gluster snapshot on 4.3.3-7) ? Best Regards,Strahil Nikolov

oVirt Node 4.3.2 Activation/Deactivation Loop
by zachary.winter＠witsconsult.com 28 May '19

28 May '19

I have a two-node cluster with one host (ovirt1) running the oVirt engine and the other running the most recent oVirt Node (4.3.2 from March 2019) software. The engine host has the following information: OS Version: RHEL - 7 - 6.1810.2.el7.centos OS Description: CentOS Linux 7 (Core) Kernel Version: 3.10.0 - 957.12.2.el7.x86_64 KVM Version: 2.12.0 - 18.el7_6.5.1 LIBVIRT Version: libvirt-4.5.0-10.el7_6.9 VDSM Version: vdsm-4.30.13-1.el7 SPICE Version: 0.14.0 - 6.el7_6.1 GlusterFS Version: [N/A] CEPH Version: librbd1-10.2.5-4.el7 Open vSwitch Version: openvswitch-2.10.1-3.el7 Kernel Features: PTI: 1, IBRS: 0, RETP: 1, SSBD: 3 VNC Encryption: Enabled Aside from the other issue I raised of seeing the "Uncaught exception occurred. Please try reloading the page. Details: (TypeError) : Cannot read property 'a' of null Please have your administrator check the UI logs" error on the main host, ovirt1 appears to functioning normally. The node (ovirt2) however is having consistent problems. The follow sequence of events is reproducible and is causing the host to enter a "NonOperational" state on the cluster: * Host ovirt2 installed * VDSM ovirt2 command ConnectStorageServerVDS failed: Message timeout which can be caused by communication issues * Host ovirt2 is not responding. Host cannot be fenced automatically because power management for the host is disabled. * Host ovirt2 cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter1. Setting Host state to Non-Operational. (5/27/1912:43:22 PM) * (Banner appears in GUI) Failed Activating Host ovirt2.witsconsult.com * Failed to connect Host ovirt2 to Storage Pool DataCenter1 (5/27/1912:47:07 PM) * Host ovirt2 cannot access the Storage Domain(s) <UNKNOWN> attached to the Data Center DataCenter1. Setting Host state to Non-Operational. (5/27/1912:47:07 PM) * Host ovirt2 is not responding. Host cannot be fenced automatically because power management for the host is disabled. (5/27/1912:47:07 PM) * VDSM ovirt2 command ConnectStorageServerVDS failed: Message timeout which can be caused by communication issues (5/27/1912:47:07 PM) I can then re-activate ovirt2, which appears as green for approximately 5 minutes and then repeats all of the above issues. What can I do to troubleshoot this?

Donating hardware to the oVirt project - a great opportunity to contribute
by Evgheni Dereveanchin 27 May '19

27 May '19

Hi everyone, My name is Evgheni and I'm in charge of the infrastructure used by oVirt to host the code, test it and serve packages to users. Currently we heavily rely on our PHX data center [1] for these tasks. It consists of several dozen bare metal servers that work as hypervisors, storage servers and bare metal CI hosts. We use them quite effectively yet the amount of workload is always growing so now is a good time to ask our community for help. If you happen to have physical servers or VMs that could be used as part of oVirt infra - please let us know. We created a page [2] describing hardware specs that would allow us make the infra more stable and grow its capacity. If you have any other ideas or input about the oVirt infra - feel free to reach out to me or start a discussion on the Infra list [3]. Regards, Evgheni [1] https://ovirt-infra-docs.readthedocs.io/en/latest/Phoenix_Lab/Overview/inde… [2] https://ovirt.org/community/get-involved/donate-hardware.html [3] https://lists.ovirt.org/

[Ovirt 4.3] Deploy engine with OVS bridge
by s.natoli＠siinfo.eu 27 May '19

27 May '19

Hi to all! I'm trying to deploy a new hosted-engine (via CLI, hosted-engine --deploy), in a fresh installation of ovirt 4.3, with OVS bridge but there are no option to make the OVS choice instead of the linux bridge. There are some documentation of how to do ovn installation? Thank you for the support

oVirt node loses gluster volume UUID after reboot, goes to emergency mode every time I reboot.
by michael＠wanderingmad.com 27 May '19

27 May '19

This only started to happen with oVirt node 4.3, 4.2 didn't have issue. Since I updated to 4.3, every reboot the host goes into emergency mode. First few times this happened I re-installed O/S from scratch, but after some digging I found out that the drives it mounts in /etc/fstab cause the problem, specifically these mounts. All three are single drives, one is an SSD and the other 2 are individual NVME drives. UUID=732f939c-f133-4e48-8dc8-c9d21dbc0853 /gluster_bricks/storage_nvme1 auto defaults 0 0 UUID=5bb67f61-9d14-4d0b-8aa4-ae3905276797 /gluster_bricks/storage_ssd auto defaults 0 0 UUID=f55082ca-1269-4477-9bf8-7190f1add9ef /gluster_bricks/storage_nvme2 auto defaults 0 0 In order to get the host to actually boot, I have to go to console, delete those mounts, reboot, and then re-add them, and they end up with new UUIDs. all of these hosts reliably rebooted in 4.2 and earlier, but all the versions of 4.3 have this same problem (I keep updating to hope issue is fixed).

SPICE and Windows 10
by Colin Coe 27 May '19

27 May '19

Hi all We've just updated our dev environment from 4.1 to RHV 4.3 and found that while a lot better, Windows 10 under SPICE still isn't great. We're running dual screen VMs at 2560x1440 resolution. The Windows login screen is particularly bad although once logged in it gets better but not great. The benchmark here is Windows 10 vs Windows 7 VMs. We've gone into settings / advanced and set "configure for best performance". Latest RHV tools (4.3-6) are installed. We've also created "/etc/ovirt-engine/osinfo.conf.d/20-overload.properties" containing: os.windows_10.devices.display.vramMultiplier.value = 4 os.windows_10x64.devices.display.vramMultiplier.value = 4 When we set the multiplier to 8, as recommended in another thread, ovirt-engine fails to restart. I know there have been a few threads on this but I'd like to ask what is the advice for RHV/oVirt 4.3 to make Windows 10 faster? VDI on RHV makes up an important part of what we do and RDP, VNC, etc are not an option. Thanks CC
