Re: Separate NFS Domain Storage for each Domain Storage
For the initial installation of the operating system in a virtual machine, you need to mount an ISO image that is located in the storage domain of the NFS type (ISO function). If the NFS server is located within a high-speed LAN (one data center), then there are no problems, if you need to connect an image to a remote site (second data center) with slow channels, then difficulties arise.

oVirt 4.3 is quite old. Anyway since 4.2 you could put iso files on your ordinary data domains, where performance access should be acceptable for any host. In 4.2.x there were some problems when swapping CDs in a running VM with iso being on block based data domains, but I think this had been fixed in 4.3 You can also put your iso in different data domains and use then the one that is better for you when you need to install an OS in a VM from iso Gianluca

Thank you for your help. ISO images uploaded via oVirt Image I/O (Open Virtualization Manager -> Storage Domain -> Disks -> Uploads) can be used as a CD. The only significant disadvantage of Storage Domain with the Data function compared to ISO is that the images are downloaded over the network first to the host with the Engine, and then transferred to the final host with NFS. This loads the channels, the Engine itself. In the case of an ISO, the image can be manually uploaded directly to the destination NFS server.
Upload the iso to one of the data domains you use for your VMs. -----Original Message----- From: Mikhail Po <porsevm@gmail.com> Sent: Tuesday, August 29, 2023 12:22 AM To: users@ovirt.org Subject: [ovirt-users] Re: Separate NFS Domain Storage for each Domain Storage For the initial installation of the operating system in a virtual machine, you need to mount an ISO image that is located in the storage domain of the NFS type (ISO function).
