Hi, I want to live migrate the iSCSI storage of QEMU/KVM virtual machines to another portal when getting out of storage capacity. The VMs are running on a diskless Linux server (Open-iSCSI initiator). When migration starts on the storage servers there will be a further synchronous replication link established to the new location. When this becomes "up-to-date" the iSCSI session change is needed.
This is the sequence: 1. pause the VM 2. unlink replication to new location, new target becomes primary 3. logout from old iSCSI target 4. login to new iSCSI target, BUT with the same block device as it is held open 5. resume the VM QEMU doesn't support changing the storage device while running. And this sequence would even be independent from the virtualization framework. Is this already possible to bind the new target to the block device in use? I would otherwise modify the initiator source code. Or are there other options? Does iSCSI target redirection work without stopping VMs?
