Subject: [PATCH] conf: Check for user aliases duplicates only

When validating a device XML config we check if user provided
|
|
|
952426 |
alias is unique. We do this by maintaining a hash table of device
|
|
|
952426 |
aliases as we iterated over all devices defined for the domain.
|
|
|
952426 |
However, it may happen that what appears as two devices in domain
|
|
|
952426 |
XML is in fact just one interface in hypervisor. We can assume
|
|
|
952426 |
libvirt generated aliases to be unique and thus really check user
|
|
|
952426 |
provided ones only.
