When introducing this check back in 4ad54a417a1 my mindset was
|
|
that if an element is missing in update XML then user is
|
|
requesting for removal of the corresponding setting. For
|
|
instance, if <bandwidth/> is not present in update XML any QoS
|
|
previously set on <interface/> is cleared out. Well this
|
|
assumption is correct but only to some extent.
|
|
|
|
Turns out, we have some users who when updating path to ISO
|
|
image construct very minimalistic disk XML and pass it to device
|
|
update API. Such XML is lacking a lot of information, and alias
|
|
is one of them. This triggers error in
|
|
virDomainDefCompatibleDevice() because we think that user is
|
|
requesting to remove the alias. Well, they are not.
