Description of problem:
As reported in https://github.com/kubevirt/kubevirt/issues/6564 hot plugging a second block device makes the first one disappear. The block device is no longer visible in the VM nor the host the VM is running on. This can cause the VM to pause on an io error.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Start a VM
2. Create 2 or more block volumes
3. Hotplug 1 volume into the VM. Note the disk is visible inside the VM
4. Hotplug another volume into the VM. Note the first disk is detached from the VM before the second one becomes visible. The first one never re-appears.

Actual results:
First volume disappears for no reason.

Expected results:
All hotplugged volumes should remain visible and accessible.
