Hi everyone, There's a maintenance window planned for this Saturday, February 2 2019 to upgrade network equipment in the PHX datacenter. The change will be implemented during afternoon hours and several oVirt infra services may be unreachable for short periods of time, specifically: * package repositories * Jenkins CI * glance image repo If you have problems accessing project resources during this period or see CI failures please re-try in a couple of hours. The project website and Gerrit code review are not affected by this outage and will continue to function normally. -- Regards, Evgheni Dereveanchin

Clearing asynchronous task Unknown
by nicolas＠devels.es 29 Jan '19

29 Jan '19

Hi, We're running oVirt 4.1.9 (I know there's a new version, we can't upgrade until [1] is implemented). The thing is that since some days we're having an event that floods our event list: Clearing asynchronous task Unknown that started at Tue Jan 22 14:33:17 WET 2019 The event shows up every minute. We tried restarting the ovirt-engine, but after some time it starts flooding again. No pending tasks in the task list. How can I check what is happening and how to solve it? Thanks.

oVirt SHE 4.2.8 and CentOS 7.6
by Vrgotic, Marko 29 Jan '19

29 Jan '19

Hi all, Looking at 4.2.8 and How Support version is EL 7.5. Does that mean that is not recommended to upgrade already running SHE to higher than EL 7.5, or it means not to deploy it on EL version lower than 7.5? Thank you. Marko Vrgotic

Ovirt snapshot issues
by Alex K 28 Jan '19

28 Jan '19

Hi all, I have ovirt 4.2.7, self-hosted on top gluster, with two servers. I have a specific VM which has encountered some snapshot issues. The engine lists 4 snapshots and when trying to delete one of them I get "General command validation failure". The VM was being backed up periodically by a python script which was creating a snapshot -> clone -> export -> delete clone -> delete snapshot. There were times where the VM was complaining of some illegal snapshots following such backup procedures and I had to delete such illegal snapshots references from the engine DB (following some steps found online), otherwise I would not be able to start the VM if it was shut down. Seems though that this is not a clean process and leaves the underlying image of the VM in an inconsistent state in regards to its snapshots as when checking the backing chain of the image file I get: *b46d8efe-885b-4a68-94ca-e8f437566bee* (active VM)* ->* *b7673dca-6e10-4a0f-9885-1c91b86616af ->* *4f636d91-a66c-4d68-8720-d2736a3765df ->* 6826cb76-6930-4b53-a9f5-fdeb0e8012ac -> 61eea475-1135-42f4-b8d1-da6112946bac -> *604d84c3-8d5f-4bb6-a2b5-0aea79104e43 ->* 1e75898c-9790-4163-ad41-847cfe84db40 -> *cf8707f2-bf1f-4827-8dc2-d7e6ffcc3d43 ->* 3f54c98e-07ca-4810-82d8-cbf3964c7ce5 (raw image) The bold ones are the ones shown at engine GUI. The VM runs normally without issues. I was thinking if I could use qemu-img commit to consolidate and remove the snapshots that are not referenced from engine anymore. Any ideas from your side? Thanx, Alex

Hello, i have tried every documentation that i found to bring GPU Passtrough with a Nvidia Grid K2 to ovirt, but i failed. I am confident that it has to run with my hardware, but i have no ideas anymore. Maybe the community can help me. Actually my VM (Win7 and Win10) crashes or hangs on startup. I have done theese steps: 1. lspci -nnk ......... 07:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104GL [GRID K2] [10de:11bf] (rev a1) Subsystem: NVIDIA Corporation Device [10de:100a] Kernel driver in use: pci-stub Kernel modules: nouveau 08:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK104GL [GRID K2] [10de:11bf] (rev a1) Subsystem: NVIDIA Corporation Device [10de:100a] Kernel driver in use: pci-stub Kernel modules: nouveau ......... 2. /etc/default/grub ......... GRUB_CMDLINE_LINUX="crashkernel=auto rd.lvm.lv=cl/root rd.lvm.lv=cl/swap rhgb quiet pci-stub.ids=10de:11bf rdblacklist=nouveau amd_iommu=on" ........ 3.

Using oVirt for Desktop Virtualization
by jarheadx＠hotmail.de 28 Jan '19

28 Jan '19

Hey guys, i want to use ovirt as my desktop enviroement. Therefore i bought a GRID K2 for GPU Passtrough. But i have still lags on video streaming for example HD Videos. I used Spice, VNC and Remote Desktop but i guess they are not good on video compression over WAN or LAN. Is there any other Remote App which allows me to use ovirt as my Virtual Desktop with smooth and reliable video output? Many Thanks Volrath

Nvidia Grid K2 and Ovirt VGPU
by jarheadx＠hotmail.de 27 Jan '19

27 Jan '19

Hello, sry for my bad english. I have just bought the NVIDIA Grid K2 and want to passtrough the vGPU to several VMS. But i am not able to manage this. I need the driver for Guest and Host, but can not download it. On the official Site of Nvidia there are only drivers for XenServer and VMWare. This Nvidia-Site tells that there is support for Ovirt (RHEV) and K2 (https://docs.nvidia.com/grid/4.6/grid-vgpu-release-notes-red-hat-el-kvm/ind… ) Can someone please tell me what is going on? Is there any possibility to run Grid K2 in Ovirt with vGpu (or Host Device Passtrough?) Furthermore if I do "vdsm-client Host hostdevListByCaps" on the Host , i do not get any mdev markers like described here: https://www.ovirt.org/documentation/install-guide/appe-Preparing_a_Host_for… Many Thanks Volrath
