Hello,

maybe a the contents of the db are better than the logs:

I have a machine with two virtio disks: The vm_device table lists:

device|                          address                           |   alias
------+------------------------------------------------------------+------------
cdrom |{unit=0, bus=1, target=0, controller=0, type=drive}         |ide0-1-0
 disk |{bus=0x00, domain=0x0000, type=pci, slot=0x06, function=0x0}|virtio-disk0
 disk |{bus=0x00, domain=0x0000, type=pci, slot=0x07, function=0x0}|virtio-disk1
 scsi |{bus=0x00, domain=0x0000, type=pci, slot=0x04, function=0x0}|scsi0

Now I reconfigure the second disk to virtio-scsi and try to start the vm. It fails and the table afterwards reads:

device|                           address                          |    alias
------+------------------------------------------------------------+------------
cdrom |{unit=0, bus=1, target=0, controller=0, type=drive}         |ide0-1-0
disk  |{bus=0x00, domain=0x0000, type=pci, slot=0x07, function=0x0}|virtio-disk1
disk  |{bus=0x00, domain=0x0000, type=pci, slot=0x06, function=0x0}|virtio-disk0
scsi  |{bus=0x00, domain=0x0000, type=pci, slot=0x04, function=0x0}|scsi0

Finally I detach and reattach the disk. VM is startable again. The table is now

disk' or device='scsi');"_id='1dec3a15-996b-44ca-9bbc-e86112e244af' and ( type='d
device|                         address                            |   alias
------+------------------------------------------------------------+-----------
cdrom |{unit=0, bus=1, target=0, controller=0, type=drive}         |ide0-1-0
disk  |{unit=0, bus=0, target=0, controller=0, type=drive}         |scsi0-0-0-0
scsi  |{bus=0x00, domain=0x0000, type=pci, slot=0x04, function=0x0}|scsi0
disk  |{bus=0x00, domain=0x0000, type=pci, slot=0x06, function=0x0}|virtio-disk0

I guess the disk change dialogue does not persist the changes correctly.
