Re: [External] : cpu pinning validation failed - virtual cpu does not exist in vm
by parallax
thanks for your reply
it looks like I stepped in and in fact the total number of cores for the VM
was less than I was trying to pin

Re: [External] : Fallback Method to Start a VM if oVirt Engine is Offline
by Tommi Finance
Hi Marcos,
thank you so much for your feedback and clarification.
I've recognized you are a big player in the Oracle Universe; we are
currently migrating from Oracle VM Server to Oracle Linux Virtualization
Manager.
the target was to include also some other Servers from VMware Hypervisor.
Potentially this is a showstopper in our strategy but we will see.
thank you again
Thomas

Storage Domain Not synchronized, To synchronize them, please move them to maintenance and then activate.
by Arup Jyoti Thakuria
Dear All,
In our Ovirt Engine Infrastructure, recently we have received an alert for one of our "Storage Domain"
The alert is as mentioned below----
===================================
Storage domains with IDs [fb34e5b7-e850-4d66-ab47-3011d2000338] could not be synchronized. To synchronize them, please move them to maintenance and then activate.
==========================================================
What is the consequence of this alert, if we ignore this what can happen to the infra, are we going to face any issue with the VMs, currently this infra is under production

Hosted Engine Boot Failure Recovery Guidance
by Clint Boggio
Good Day oVirt Community
I've experienced a condition whereby the HE on my three-node cluster will not boot. Connecting to the hosted-engine console reveals that the hosted engine is in the "grub rescue" prompt. I don't really know how to rescue the engine from that level of failure but if anybody can give me a quick set of steps to maybe cover that engine I'd appreciate it and certainly give it my best try.
If it's easier to re-deploy the engine and leverage a backup file in the process I have such a backup file created yesterday readily available. I would need a link to a process for decommissioning the dead machine, and re-deploying the replacement HE from the backup file.
Any help would be greatly appreciated.

Hi,
I just install last ovirt version ( Version 4.5.6-1.el9) using CentOS Stream 9.

Re: [External] : Import disk and ISO failed status "Paused by System"

Thank you Sungaila!
I installed ovirt-engine on another server in a virtual machine running on
KVM and it solved the problem.
