But the problem is that you are not checking any assignment. The code
is not executed at all. That's because you specify 'target dev=' from
which we're trying to guess the right address.

Because virDomainDeviceDefPostParseInternal() is ran for the device
definition and it calls virDomainDiskDefAssignAddress() which in turn
calls virDiskNameToIndex().

virDomainDiskDefAssignAddress() is called only when disk->info.type

is VIR_DOMAIN_DEVICE_ADDRESS_TYPE_NONE, and in my testcases,

disk->info.type is equal to VIR_DOMAIN_DEVICE_ADDRESS_TYPE_CCW,

so this function isn’t even executed. Besides even if it went inside that function,

this device’s bus is set to VIR_DOMAIN_DISK_BUS_VIRTIO, so this function

wouldn’t do anything, because it deals only with buses that are controller-based.

To make sure, I confirmed that it is virDomainCCWAddressAssign()

that assigns addresses in my testcases. I checked that the parameters

are correct (autoassign is false when the address is explicit etc), and this

is what I wanted to test.

Thanks for the heads up though!
