When trying to update an interface's rom settings with an device XML that is missing the PCI addr element, all new rom settings where not applied. https://bugzilla.redhat.com/show_bug.cgi?id=1599513 Signed-off-by: Katerina Koukiou <kkoukiou@xxxxxxxxxx> --- Not sure why we chose to overwrite the whole info before though, I hope that this doesn't cause side problems.
It allows the user to omit parts of the XML that do not need changing. By dropping the virDomainDeviceInfoCopy call, we start validating the attributes that weren't provided in the XML. If we want to keep this convenience functionality, we should also autofill other fields of virDomainDeviceInfo which weren't provided in the XML.
