Fixed In Version: ovirt-engine-4.5.0
Doc Type: Bug Fix
Doc Text:
Previously, when hot plugging multiple disks with VIRTIO SCSI interface to virtual machine that are defined with more than one IO thread, this would have failed due to allocation of a duplicate PCI address. Now, each disk is assigned with a unique PCI address in this process, which enabled to plug multiple disks with VIRTIO SCSI to virtual machines also when they are set with more than one IO thread.

Description of problem:

Trying to hotplug a disk in RHV but failing with the error "Requested operation is not valid: Domain already contains a disk with that address, code = 45".
Selecting VIrtIO disk get Hotplug successfully.

There are various bugs for the same issue in RHV 4.3 which got Fixed in RHV 4.4.7 but still failing in RHV 4.4.9

Verified with:
ovirt-engine-4.5.0.2-0.7.el8ev.noarch

Steps:
1. Create and run a VM with IO threads>1(created VM from template latest-rhel-guest-image-8.6-infra, set IO threads to 4)
2. Create 5 new disks
3. Hot plug the 5 disks to the VM with VIRTIO SCSI interface

Result:
All the 5 disks are hot plugged to the VM successfully.
