[libvirt PATCH 04/10] virDomainFeaturesHyperVDefParse: Read attribute "mode" of element "hyperv"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Currently, this attribute may either have a value of "custom", or be absent
(which defaults to "custom"), for backwards compatibility.
