USB Redirection - Auto choose devices
by jamie.briscoe＠johnstonnc.com 28 Dec '22

28 Dec '22

Is there a way to auto choose which devices get redirected the the guest? I have a Windows 2022 VM and I can connect to is using the VM portal and Spice (virt-viewer) and it opens fullscreen perfectly. Perfect VDI solution... Except the fact that I have to click in the top menu and choose my usb devices every time I connect to the vm... I need it to save my selections... Any way to do this?

Network Address Change
by Paul.LKW 28 Dec '22

28 Dec '22

Hi All: I just has a case, I need to change the oVirt host and engine IP address due to data center decommission I checked in the hosted-engine host there are some files I could change ; in ovirt-hosted-engine/hosted-engine.conf ca_subject="O=simple.com, CN=1.2.3.4" gateway=1.2.3.254 and of course I need to change the ovirtmgmt interface IP too, I think just change the above line could do the tick, but where could I change the other host IP in the cluster ? I think I have to be lost all the host as once changed the hosted-engine host IP as it is in diff. sub net. Does there any command line tools could do that or someone has such experience could share? Best Regards, Paul.LKW

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?

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

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.

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!
