Re: ovirtmgmt VLAN and IP Change

Your method worked ! I additionally had to run the engine rename service script to change the hostname of the engine as well. My only issue now is after readding all the nodes with new hostnames my main host node 1 will not allow me to remove and re-add as a new hostname as there is a gluster volume on it. It will not let me remove to readd because theres a gluster on the volume, have you run into this?

How did you do this if the host had a gluster volume on it though? Mine does not let me remove due to that.

ovirtmgmt VLAN and IP Change
by Abe E 19 Feb '22

19 Feb '22

Hello All, So due to some issues with provisioning new networks in our lab, I have to use a different VLAN in for my ovirt cluster. Cluster -> 3 Hosts (Hyperconverged) What I want to do is essentially change the Ovirtmgmt interface to another vlan but also change the IP Schemes, I wont be needing to change the storage network vlans. I am just wondering how this is done safely. Can I through the engine, put the host 1 by 1 into maint mode and manually adjust the IPs and apply and reconfigure the switch port? What about the IP that the engine has set or would I change that manually through console once I change the ovirtmgmt vlan on all the nodes?

Random reboots
by Pablo Olivera 17 Feb '22

Hi community, We're dealing with an issue as we occasionally have random reboots on any of our hosts. We're using ovirt 4.4.3 in production with about 60 VM distributed over 5 hosts. We've a virtualized engine and a DRBD storage mounted by NFS. The infrastructure is interconnected by a Cisco 9000 switch. The last random reboot was yesterday February 14th at 03:03 PM (in the log it appears as: 15:03 due to our time configuration) of the host: 'nodo1'. At the moment of the reboot we detected in the log of the switch a link-down in the port where the host is connected. I attach log of the engine and host 'nodo1' in case you can help us to find the cause of these random reboots. Thanks in advance. Pablo.

Thanks for reply Angus, IPMI/DCMI over LAN is enable On ILO4 I created account for Ovirt with full credential and now it's works with ILO4 The ports and protocol are enable, but Ovirt works only ip_ssh and ILO4, no ipmilan. Do you know which keys I have to set in the option section of the agent fence on Ovirt? Thanks

Cannot add Virtual Disk. Disk configuration (RAW Sparse backup-None) is incompatible with the storage domain type.

Hi, We're using oVirt 4.4.8.6. We make an intensive use of the VM portal because we've hundreds of students creating their own VMs. Recently, one of the professors reported that they are encountering an error when adding a disk to a newly created VM. They are creating ISO based VMs (CentOS-8-Stream in this case), everything goes smoothly but when adding a thin-provisioned disk, this error shows up: 2022-02-17 09:56:28,073Z INFO [org.ovirt.engine.core.bll.storage.disk.AddDiskCommand] (default task-39078) [0332e7b6-80b1-48e9-b849-80698f2ce7ab] Lock Acquired to object 'EngineLock:{exclusiveLocks='[e4a02ab9-31e4-4e8c-8999-91700263ff08=VM_DISK_BOOT]', sharedLocks='[e4a02ab9-31e4-4e8c-8999-91700263ff08=VM]'}' 2022-02-17 09:56:28,446Z WARN [org.ovirt.engine.core.bll.storage.disk.AddDiskCommand] (default task-39078) [0332e7b6-80b1-48e9-b849-80698f2ce7ab] Validation of action 'AddDisk' failed for user aluX@domain-authz.

Disk configuration (RAW Sparse backup-None) is incompatible with the storage domain type.] However, changing the provisioning to thick does work and the disk can be added. I found [1] which talks about this but I'm not sure if it's the same issue, nor it has a solution yet. Is this a known bug? Does it have any workaround beyond creating thick-provisioned disks? Thanks. Nicolás [1]: https://access.redhat.com/solutions/6022811

Enable Power Management Ovirt 4.3
by emiliano.pozzessere＠satservizi.eu 17 Feb '22

Hi guys, I would like enable Power Management on Ovirt 4.3. My Hosts are HP with ILO4, I configured on ILO4 account for Ovirt. On the host enable Power Management, flag on Kdump Integration and I added the fence agent, I put the user and password and set up ILO4 but the test fails, if I put ilo_ssh it works. But I don't know which keys I have to enter and with which values (if necessary) Can anyone explain to me? Thanks
