Hi all, in the past we have used customized ipxe (to allow boot over network with 10G cards), now we have finally updated our hypervisors to the latest ipxe-roms-qemu Of course the sum now differs and during live-migration the libvirtd throws this error: Mar 4 11:37:14 hypevisor-01 libvirtd: 2019-03-04 10:37:14.084+0000: 15862: error : qemuMigrationJobCheckStatus:1313 : operation failed: migration out job: unexpectedly failed Mar 4 11:37:15 hypevisor-01 libvirtd: 2019-03-04T10:37:13.941040Z qemu-kvm: Length mismatch: 0000:00:03.0/virtio-net-pci.rom: 0x20000 in != 0x40000: Invalid argument Mar 4 11:37:15 hypevisor-0 libvirtd: 2019-03-04T10:37:13.941090Z qemu-kvm: error while loading state for instance 0x0 of device 'ram' Mar 4 11:37:15 hypevisor-0 libvirtd: 2019-03-04T10:37:13.941530Z qemu-kvm: load of migration failed: Invalid argument is there an easy command we can use to identify what guests are still using the old .rom and must be powercycled ?

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.

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

Re: low power, low cost glusterfs storage

The problem is that anything on the budged doesn't have decent network + enough storage slots.

Cannot assign Network to Mellanox Interface
by cbop.mail＠gmail.com 02 Mar '19

02 Mar '19

Hello, I want to use my Infiniband Network for Storage Access, so I created a new network and tried to assign it to a host. When I do this, I get a success message but it's actually not assigned to my Infiniband NIC. I'm running the latest CentOS with the latest Mellanox OFED drivers and multiple Subnet Managers are running on the network. The NIC is a Mellanox ConnectX-2 VPI, set to Infiniband mode. I didnt't knew which logs to send, so when you need to look into a log, just tell me which one you need. I hope you can help me out. Roman Meusch

oVirt 4.3 and dual socket hosts : numad?

Is it recommended to enable numad service for automatic NUMA memory optimization? I could not find any recommendation on that front for oVirt ; all benchmarks and documentation I could find are from around ~2015 I see that kernel autonuma balancing is on : cat /proc/sys/kernel/numa_balancing 1 Not sure which is better as of now.

impact of --emulate512 setting for VDO volumes
by Guillaume Pavese 02 Mar '19

02 Mar '19

Hello, We are planning to deploy VDO with oVirt 4.3 on centos 7.6 (on SSD devices). As oVirt does not support 4K devices yet, VDO volumes are created with the parameter "--emulate512 enabled" What are the implications of this setting? Does it impact performance? If so, is it IOPS or throughput that is impacted? What about reliability (is that mode equally tested as standard mode)? As I saw on RH Bugzilla, support for 4K devices in oVirt will need to wait at least for Centos 7.7 Once that is supported, would it be possible to transition/upgrade an emulate512 vdo volume to a standard one? Thanks, Guillaume Pavese Ingénieur Système et Réseau Interactiv-Group
