VM stuck reading and writing to disk
by Murilo Morais 28 Dec '22

28 Dec '22

Good morning people. I'm experiencing a weird problem. I have a specific VM that the IO simply crashes. This VM, during the backup period, executes mysqldump and tries to compress, after a long period of compacting the JBD2 process appears using 100% of the CPU and also of WA (Wait in the TOP command). Numerous other VMs perform the same process but only this one remains in this state. When JBD2 appears, it is necessary to perform a forced reboot, because it stops practically everything. I'm using CephFS as Storage Backend. In the VM I can get rates of at least 600 Megs, I can generate gigs and more gigs of data without any problem. The VMs are using Virtio instead of Virtio-blk. Hosts are interconnected on 10G SFP+ interfaces, Storages on 40G interfaces. I believe that the problem is not the Storage, as this behavior does not exist in other VMs. What I find strange is that JBD2 goes up and spikes at 100%. What could be happening? Could it be something in the Guest itself?

Ovirt-node don't communicate with qemu-agent
by Fernando Hallberg 28 Dec '22

Hi all, I reinstalled one of the ovirt-nodes, with ovirt-4.5.4, and after the reinstallation the agents of the vms connected to this node cannot communicate with the ovirt-engine. ovirt-engine 4.5.4 any idea? VMs work perfectly, but the agent doesn't communicate. Best regards, Fernando Hallberg

Certificate expiration w/o warning on all clients. Cluster in zombie state
by Gilboa Davara 28 Dec '22

28 Dec '22

Hello all, Even though I do my best to keep track of the certificate issue date across my different clusters, I somehow missed the vdsm certificate expiration in one of my clusters. Now I have an active cluster with multiple nodes (self-hosted / gluster storage), vdsm service is down on all nodes (due to certificate expiration) - hence, I cannot get the cluster into global maintenance mode (vdsms are down), and I cannot access my engine (to renew the engine certificates / re-enroll hosts). How can manual renew the host certificate? Thanks, Gilboa

Import FC LUN copy/snapshot as storage domain
by KSNull Zero 27 Dec '22

Hello! Is it possible to import a FC LUN copy/snapshot as additional storage domain to oVirt to copy large disk from it ? I believe that this LUN will have the same serial as existing one storage domain. How can we accomplish this ? Thank you.

RBD support
by Murilo Morais 27 Dec '22

Good night people! How is CEPH (RBD) supported through Cinderlib? How about latency? Is it more performant to use CephFS or RBD through Cinderlib? Thanks a lot in advance!

Unable to sync network settings on new Ovirt installation
by Patrick Lomakin 24 Dec '22

24 Dec '22

Hi guys! I encountered a network error that I had not encountered before in a previous installation. I need to set up another network in addition to the ovirtmgmt network to migrate virtual machines, because when migrating a large number of machines, the ovirtmgmt network is loaded to its maximum. And as you know and documentation - all or none of the networks must or must not have a QoS rule. After creating the migration network, I added this network QoS rule and also added QoS to the ovirtmgmt network. But I get this kind of error - Error while executing action HostSetupNetworks: Unknown exception. In the logs I noticed the following: {'reason': "(2, 'Error: TC classifier not found.\nWe have an error talking to the kernel\\n', ['/sbin/tc', 'filter', 'replace', 'dev', 'bond0', 'protocol', 'all', 'parent', '1389:', 'pref', '200', 'basic', 'match', 'meta(vlan eq 200)', 'flowid', '1389:c8')"} Who can tell me where to put my energy to find a solution?) Good luck everyone!
