There's a simple method really. You need to create a preallocated disk of the similar size (maybe a little bit larger to be safe) and note it's UUID.

Then copy the qcow2 image to a host that has access to the storage domain

enable the LV for thie new disk using lvchange -ay /dev/mapper/vg-uuid (look it up in the output of lvs -o +tags)

run qemu-img convert from qcow2 to raw/qcow2 (whatever you set the disk up to be in ovirt) using the qcow2 file as source and the LV as destination.

Now you should be able to use the disk in a VM or a template.

PS Exxonmobil on oVirt, that's a major wow :)

I am trying to upload an image.qcow2 from a previous kvm installation to a block iscsi storage domain if possible, if I have to first stand up and NFS storage domain I could do that as well and move the disk once its uploaded, I just cannot get it uploaded.

I know there is a method for importing from a KVM provider via the following link https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/html/administration_guide/sect-adding_external_providers#Adding_KVM_as_an_External_Provider However all I have is the disk image, the KVM environment it was running in is no longer operational. So I am looking for a simple command line method to upload the image, similar to how one could use the ovirt-iso-uploader to upload an image to an iso domain.

Is that block or file storage?

Hello, I am in a precarious situation where I need to upload an image to the storage domain, I understand that normally you would achieve this via the upload button on the storage domain > Disks tab. However I currently do not have the ability to import the certificate. Is there a way from command line either on the RHV manager or otherwise to upload a qcow2 without using the image upload through the GUI?

Thank you.
