VM With Snapshots Marked As Illegal
by Clint Boggio 05 Mar '19

05 Mar '19

Greetings oVirt Users; Environment: oVirt 4.2.0.2-1 1 Dedicated Engine 6 Hypervisor Nodes iSCSI Storage All running CentOS 7.5 I have a VM with the illegal snapshot error. After doing some research on the condition i have found some methods for fixing the problem by connecting to the database and repairing the fault. I am unable to connect to the engine database from the engine command line with the password in 10-setup-database.conf for whatever reason. (likely user error) I don't really need the disk that is attached to this VM that is at fault as it is a disk that is being utilized by the VM to perform local backups and that function has been moved to an offsite backup solution. If I shut down the afflicted VM, then delete the un-needed disk, will the snapshots be deleteed and thus the problem alleviated ? Or will the system not delete the un-needed disk because of the fault and then not reboot because if the illegal statu of the snapshot ? I have tried to delete the snapshots, and the system refuses to do so. I may need some guidance regarding connecting to my engine database if i cannot delete the un-needed disk. Thank you all for any help in this matter, and if more information is needed please let me know. ~Clint Boggio

problems getting vGPU working
by cmc 05 Mar '19

05 Mar '19

Hi, I'm having trouble getting my Nvidia vGPU to work on a VM. Setup: RHEV 4.2 on RHEL 7.5, Tesla M60 (switched to graphics mode). I'm using the NVIDIA-GRID-RHEL-7.5-410.92-410.91-412.16.zip package from Nvidia. On the hypervisor, I've installed the NVIDIA-vGPU-rhel-7.5-410.91.x86_64 rpm. vfio kernel modules are loaded, nvidia-smi shows the card, and I can see all the vGPUs via vdsm-client I've created a CentOS 7.4 VM and added a 'B' type vGPU instance in 'custom properties'. I've configured gridd.conf to point to the license server and it reports picking up a license in /var/log/messages. I installed the driver via the .run file (NVIDIA-Linux-x86_64-410.92-grid.run). The nvidia kernel module is loaded, but so also is the 'qxl' paravirtual driver. lspci reports: 00:02.0 VGA compatible controller: Red Hat, Inc.

by shanep＠lifestylepanel.com 05 Mar '19

Trying to install oVirt hosted engine on a dedicated host in Data Centre. But it keeps failing at what looks to be the point where it is trying to get an IP if virbr0, which has been created successfully during setup, but does not appear to have an ip address. Any idea what could be going worng? System is running Centos 7.6.1810 Interface: em1 (public ip) Interface: em2 management network. This is the error in the log [ INFO ] TASK [ovirt.hosted_engine_setup : Fetch IPv4 CIDR for virbr0] [ ERROR ] fatal: [localhost]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'ipv4'\n\nThe error appears to have been in '/usr/share/ansible/roles/ovirt.hosted_engine_setup/tasks/bootstrap_local_vm/01_prepare_routing_rules.yml': line 57, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n tags: ['skip_ansible_lint']\n - name: Fetch IPv4 CIDR for {{ virbr_default }}\n ^ here\nWe could be wrong, but this one looks like it might be an issue with\nmissing quotes.

low power, low cost glusterfs storage
by Jonathan Baecker 04 Mar '19

04 Mar '19

Hello everybody! Does anyone here have experience with a cheap, energy-saving glusterfs storage solution? I'm thinking of something that has more power than a rasbian Pi, 3 x 2 TB (SSD) storage, but doesn't cost much more and doesn't consume much more power. Would that be possible? I know the "Red Hat Gluster Storage" requirements, but are they generally so high? Only a few VM images would have to be on it... Greetings Jonathan
